What the Bible Says About the Definition of Priesthood

In the Bible, the priesthood refers to the divinely appointed role of individuals who conduct religious ceremonies, offer sacrifices, and intercede on behalf of the people before God. Specifically, the Levitical priesthood in the Old Testament is established to serve in the Tabernacle and later the Temple, while the New Testament presents Jesus as the ultimate High Priest who fulfills and transcends the Levitical system.

Scripture

1 “Then bring near to you Aaron your brother, and his sons with him, from among the people of Israel, to serve me as priests—Aaron and Aaron’s sons, Nadab and Abihu, Eleazar and Ithamar.”
2 And you shall make holy garments for Aaron your brother, for glory and for beauty.
3 You shall speak to all the skillful, whom I have filled with a spirit of skill, that they make Aaron’s garments to consecrate him for my priesthood.
4 These are the garments that they shall make: a breastpiece, an ephod, a robe, a coat of checker work, a turban, and a sash. They shall make holy garments for Aaron your brother and his sons to serve me as priests.
5 They shall take the gold, blue and purple and scarlet yarns, and fine twined linen.
6 “And they shall make the ephod of gold, of blue and purple and scarlet yarns, and of fine twined linen, skillfully worked.
7 It shall have two shoulder pieces attached to its two edges, so that it may be joined together.
8 And the skillfully woven band on it shall be made like it and be of one piece with it, of gold, blue and purple and scarlet yarns, and fine twined linen.
9 You shall take two onyx stones, and engrave on them the names of the sons of Israel,
10 six of their names on the one stone, and the remaining six on the other stone, in the order of their birth.
11 With the work of an engraver in stone, like the engravings of a signet, you shall engrave the two stones with the names of the sons of Israel. You shall enclose them in settings of gold filigree.
12 And you shall set the two stones on the shoulder pieces of the ephod, as stones of remembrance for the sons of Israel. And Aaron shall bear their names before the Lord on his two shoulders for remembrance.
13 You shall make settings of gold filigree,
14 two chains of pure gold, twisted like cords; and you shall attach the corded chains to the settings.
15 “You shall make a breastpiece of judgment, in skilled work. In the style of the ephod you shall make it—of gold, blue and purple and scarlet yarns, and fine twined linen shall you make it.
16 It shall be square and doubled, a span its length and a span its breadth.
17 You shall set in it four rows of stones. A row of sardius, topaz, and carbuncle shall be the first row;
18 and the second row a turquoise, a sapphire, and an emerald;
19 and the third row a jacinth, an agate, and an amethyst;
20 and the fourth row a beryl, an onyx, and a jasper. They shall be set in gold filigree.
21 There shall be twelve stones with their names according to the names of the sons of Israel. They shall be like signets, each engraved with its name, for the twelve tribes.
22 You shall make on the breastpiece twisted chains like cords, of pure gold.
23 You shall make on the breastpiece two rings of gold, and shall put the two rings on the two edges of the breastpiece.
24 and you shall put the two cords of gold in the two rings at the edges of the breastpiece.
25 And the other two ends of the two cords you shall attach to the two settings of filigree, and so attach it in front to the shoulder pieces of the ephod.
26 And you shall make two rings of gold, and attach them to the two shoulder pieces of the ephod, at its front, above the skillfully woven band of the ephod.
27 And you shall make two rings of gold, and attach them in front to the lower part of the two shoulder pieces of the ephod, at its seam above the skillfully woven band of the ephod.
28 And they shall bind the breastpiece by its rings to the rings of the ephod with a lace of blue, so that it may lie on the skillfully woven band of the ephod, so that the breastpiece shall not come loose from the ephod.
29 So Aaron shall bear the names of the sons of Israel in the breastpiece of judgment on his heart, when he goes into the Holy Place, to bring them to regular remembrance before the Lord.
30 And in the breastpiece of judgment you shall put the Urim and the Thummim, and they shall be on Aaron’s heart, when he goes in before the Lord. Thus Aaron shall bear the judgment of the people of Israel on his heart before the Lord regularly.
31 “You shall make the robe of the ephod all of blue.”
32 It shall have an opening for the head in the middle of it, with a woven binding around the opening, like the opening in a garment, so that it may not tear.
33 On its hem you shall make pomegranates of blue and purple and scarlet yarns, around its hem, with bells of gold between them,
34 A golden bell and a pomegranate, a golden bell and a pomegranate, around the hem of the robe.
35 It shall be on Aaron when he ministers, and its sound shall be heard when he goes into the Holy Place before the Lord, and when he comes out, so that he does not die.
36 “You shall make a plate of pure gold and engrave on it, like the engraving of a signet, ‘Holy to the Lord.’
37 You shall fasten it on a cord of blue and it shall be on the turban; it shall be at the front of the turban.
38 It shall be on Aaron’s forehead, and Aaron shall bear any guilt from the holy things that the people of Israel consecrate as their holy gifts. It shall regularly be on his forehead, that they may be accepted before the Lord.
39 “You shall weave the coat in checker work of fine linen, and you shall make a turban of fine linen, and you shall make a sash embroidered with needlework.
40 “For Aaron’s sons you shall make coats and sashes and caps. You shall make them for glory and beauty.
41 And you shall put them on Aaron your brother, and on his sons with him, and shall anoint them and ordain them and consecrate them, that they may serve me as priests.
42 You shall make for them linen undergarments to cover their naked flesh. They shall reach from the hips to the thighs;
43 They shall be on Aaron and on his sons when they go into the tent of meeting or when they come near the altar to minister in the Holy Place, lest they bear guilt and die. This shall be a statute forever for him and for his offspring after him.

Exodus 28:1-43

Biblical Definition of Priesthood

The concept of priesthood in the Bible extends beyond the mere function of conducting rituals and offering sacrifices. It embodies a deeper spiritual significance related to mediation between God and humanity. In the Old Testament, the Levitical priesthood, chosen from the tribe of Levi, was consecrated to serve in the Sanctuary (Exodus 28:1). The priests were responsible for safeguarding the holiness of God’s presence, performing sacrifices for atonement, and teaching the law (Leviticus 10:11; Malachi 2:7). This priestly role highlights the importance of holiness, purity, and the need for an intermediary between a holy God and a sinful people, emphasizing God’s desire for fellowship with humanity, despite the barriers sin creates.

In the New Testament, this notion of priesthood evolves significantly with the revelation of Jesus Christ as the ultimate High Priest (Hebrews 4:14-16). Unlike the Levitical priests, who had to make sacrifices repeatedly, Jesus offered Himself as a single, perfect sacrifice once and for all (Hebrews 9:12). This act not only fulfilled the requirements of the Old Testament sacrificial system but also established a new covenant, granting all believers direct access to God (Hebrews 10:19-22). Furthermore, in 1 Peter 2:9, believers are collectively described as a “royal priesthood,” suggesting that the function of priesthood is now extended to all followers of Christ. This reflects a shift from a specialized group tasked with mediation to a community of believers called to represent God in the world, highlighting the inclusive nature of God’s redemptive plan and the priestly ministry of all Christians to proclaim His praises.

Beyond the roles of the Levitical priests, the Old Testament also introduces the concept of the priestly function in relation to the community’s relationship with God. For instance, the priesthood is seen in the context of intercession, where priests would stand before God on behalf of the people, likely rooted in the understanding of God’s mercy and grace. In books like Numbers, priests are entrusted with the responsibility of blessing the people, indicating that their role was also one of encouragement and spiritual guidance, helping the community maintain a right relationship with God through ritual and instruction. This connection illustrates that priesthood was not limited to sacrificial rites, but involved a holistic engagement with the spiritual welfare of the community, establishing a deeper bond with God through ceremonial acts and teaching.

As the narrative of the Bible unfolds, the concept of priesthood is reinterpreted in various prophetic and wisdom literature writings. For example, the prophetic books bring forth critiques of the priests who neglect their duties or lead the people astray, emphasizing that true priesthood is not merely about conducting rituals but living faithfully in accordance with God’s commands. This highlights that genuine priestly work requires integrity, moral character, and a commitment to justice and mercy. Furthermore, wisdom literature, particularly in Psalms, reinforces the idea of priesthood as a life aligned with divine wisdom and righteousness, suggesting that the essence of priesthood encompasses a way of life that reflects God’s character, ultimately preparing the way for the fulfilled priestly role in Christ, who embodies perfect obedience and divine intercession.

The Role of Mediator Between God and Humanity

In the biblical context, the priesthood serves as a vital link between God and the people. Priests are appointed to mediate, offering sacrifices and prayers on behalf of the community. This role emphasizes the importance of intercession and the need for a representative who can approach the divine on behalf of others, highlighting the relational aspect of faith and worship.

The Call to Holiness and Service

Priests are not only mediators but also exemplars of holiness and moral integrity. Their lives are meant to reflect the character of God, serving as models for the community. This aspect of the priesthood underscores the call to live a life set apart for divine service, emphasizing the importance of personal holiness and ethical conduct in fulfilling one’s duties to God and others.

The Universal Priesthood of Believers

In the New Testament, the concept of priesthood expands beyond a specific lineage or class to include all believers. This universal priesthood signifies that every follower of Christ has direct access to God and is called to serve in various capacities within the community of faith. This democratization of the priesthood emphasizes the idea that all believers are empowered to minister, worship, and represent God in their daily lives, fostering a sense of shared responsibility in the spiritual life of the church.

How to Embrace Spiritual Leadership for a Stronger Faith

Embracing spiritual leadership is a transformative journey that can significantly strengthen your faith and deepen your relationship with God. Start by recognizing that spiritual leadership is not about authority or position, but about serving others with love and humility, just as Jesus did. Engage in prayer and seek guidance from the Holy Spirit to help you discern your unique gifts and how you can use them to uplift your community. Surround yourself with fellow believers who inspire you and challenge you to grow, and don’t hesitate to step out of your comfort zone—whether that means leading a small group, volunteering in your church, or simply being a listening ear for someone in need. Remember, spiritual leadership is about being a reflection of Christ’s love, and as you lead by example, you’ll find that your own faith flourishes in the process. Embrace this calling with an open heart, and watch how God works through you to impact the lives of those around you.

36 Thus Aaron and his sons did all the things that the Lord commanded by Moses.

Numbers 3:1-13: 1 These are the generations of Aaron and Moses at the time when the Lord spoke with Moses on Mount Sinai.
2 These are the names of the sons of Aaron: Nadab the firstborn, and Abihu, Eleazar, and Ithamar.
3 These are the names of the sons of Aaron, the anointed priests, whom he ordained to serve as priests.
4 But Nadab and Abihu died before the Lord when they offered unauthorized fire before the Lord in the wilderness of Sinai, and they had no children. So Eleazar and Ithamar served as priests in the lifetime of Aaron their father.
5 And the Lord spoke to Moses, saying:
6 “Bring the tribe of Levi near, and set them before Aaron the priest, that they may minister to him.
7 They shall keep guard over him and over the whole congregation before the tent of meeting, as they minister at the tabernacle.
8 They shall guard all the furnishings of the tent of meeting, and keep guard over the people of Israel as they minister at the tabernacle.
9 And you shall give the Levites to Aaron and his sons; they are wholly given to him from among the people of Israel.
10 And you shall appoint Aaron and his sons, and they shall guard their priesthood. But if any outsider comes near, he shall be put to death.”
11 And the Lord spoke to Moses, saying,
12 “Now behold, I have taken the Levites from among the people of Israel instead of every firstborn who opens the womb among the people of Israel. The Levites shall be mine,”
13 for all the firstborn are mine. On the day that I struck down all the firstborn in the land of Egypt, I consecrated for my own all the firstborn in Israel, both of man and of beast. They shall be mine: I am the Lord.”

Deuteronomy 18:1-8: 1 “The Levitical priests, all the tribe of Levi, shall have no portion or inheritance with Israel. They shall eat the Lord’s food offerings as their inheritance.”

6 “And if a Levite comes from any of your towns out of all Israel, where he lives—and he may come when he desires—to the place that the Lord will choose,
7 then he may minister in the name of the Lord his God, like all his fellow Levites who stand to minister there before the Lord.
8 They shall have equal portions to eat, besides what comes from the sale of his patrimony.

1 Samuel 2:27-36: 27 And there came a man of God to Eli and said to him, “Thus says the Lord, ‘Did I indeed reveal myself to the house of your father when they were in Egypt subject to the house of Pharaoh?
28 Did I choose him out of all the tribes of Israel to be my priest, to go up to my altar, to burn incense, to wear an ephod before me? I gave to the house of your father all my offerings by fire from the people of Israel.
29 Why then do you scorn my sacrifices and my offerings that I commanded for my dwelling, and honor your sons above me by fattening yourselves on the choicest parts of every offering of my people Israel?’
30 Therefore the Lord, the God of Israel, declares: ‘I promised that your house and the house of your father should go in and out before me forever,’ but now the Lord declares: ‘Far be it from me, for those who honor me I will honor, and those who despise me shall be lightly esteemed.’
31 Behold, the days are coming when I will cut off your strength and the strength of your father’s house, so that there will not be an old man in your house.
32 Then you will see distress in the tent that is to befall Israel, and there shall not be an old man in your house forever.
33 The only one of you whom I shall not cut off from my altar shall be spared to weep his eyes out to grieve his heart, and all the descendants of your house shall die by the sword of men.
34 And this that shall come upon your two sons, Hophni and Phinehas, shall be the sign to you: both of them shall die on the same day.
35 And I will raise up for myself a faithful priest, who shall do according to what is in my heart and in my mind. And I will build him a sure house, and he shall go in and out before my anointed forever.
36 And everyone who is left in your house shall come to implore him for a piece of silver or a loaf of bread and shall say, “Please put me in one of the priests’ places, that I may eat a morsel of bread.”

1 Chronicles 23:13-32: 13 The sons of Amram: Aaron and Moses. Aaron was set apart to dedicate the most holy things, that he and his sons forever should make offerings before the Lord and minister to him and pronounce blessings in his name forever.
14 But as for Moses the man of God, his sons were named among the tribe of Levi.
15 The sons of Moses: Gershom and Eliezer.
16 The sons of Gershom: Shebuel the chief.
17 The sons of Eliezer: Rehabiah the chief. Eliezer had no other sons, but the sons of Rehabiah were very many.
18 But the sons of Amram: Aaron and Moses. Aaron was set apart to dedicate the most holy things, that he and his sons forever should make offerings before the Lord and minister to him and pronounce blessings in his name forever.

22 Eleazar died having no sons, but only daughters; their kinsmen, the sons of Kish, married them.
23 The sons of Mushi: Mahli, Eder, and Jeremoth, three.
24 These were the sons of Levi by their fathers’ houses, the heads of fathers’ houses as they were listed according to the number of the names of the individuals from twenty years old and upward who were to do the work for the service of the house of the Lord.
25 For David said, “The Lord, the God of Israel, has given rest to his people, and he dwells in Jerusalem forever.
26 So the Levites no longer need to carry the tabernacle or any of the things for its service.”
27 For by the last words of David the sons of Levi were numbered from twenty years old and upward.
28 For their duty was to assist the sons of Aaron for the service of the house of the Lord, having the care of the courts and the chambers, the cleansing of all that is holy, and any work for the service of the house of God.
29 For both the sons of Aaron, the priests, and the Levites shall have a portion before the Lord in all the towns, the pasturelands of the cities.
30 And they were to stand every morning, thanking and praising the Lord, and likewise at evening,
31 and whenever burnt offerings were offered to the Lord on Sabbaths, new moons, and feast days, according to the number required of them, regularly before the Lord.
32 Thus they were to keep charge of the tent of meeting and the sanctuary, and to attend the sons of Aaron, their brothers, for the service of the house of the Lord.

2 Chronicles 26:16-21: 16 But when he was strong, he grew proud, to his destruction. For he was unfaithful to the Lord his God and entered the temple of the Lord to burn incense on the altar of incense.
17 But Azariah the priest went in after him, with eighty priests of the Lord who were men of valor,
18 And they withstood King Uzziah and said to him, “It is not for you, Uzziah, to burn incense to the Lord, but for the priests, the sons of Aaron, who are consecrated to burn incense. Go out of the sanctuary, for you have done wrong, and it will bring you no honor from the Lord God.”
19 Then Uzziah was angry. Now he had a censer in his hand to burn incense, and when he became angry with the priests, leprosy broke out on his forehead in the presence of the priests in the house of the Lord, by the altar of incense.
20 Then Azariah the chief priest and all the priests looked at him, and behold, he was leprous in his forehead! And they rushed him out quickly, and he himself hurried to go out, because the Lord had struck him.
21 And Uzziah the king was a leper to the day of his death, and being a leper lived in a separate house, for he was excluded from the house of the Lord. And Jotham his son was over the king’s household, governing the people of the land.

Ezra 2:61-63: 61 Also, of the people of the priests: the sons of Habaiah, the sons of Hakkoz, the sons of Barzillai (who had taken a wife of the daughters of Barzillai the Gileadite and was called by their name).
62 These sought their registration among those enrolled in the genealogies, but they were not found there, and so they were excluded from the priesthood as unclean.

4 The Lord has sworn and will not change his mind, “You are a priest forever after the order of Melchizedek.”

19 The word of the Lord came to Jeremiah:
20 “Thus says the Lord: If you can break my covenant with the day and my covenant with the night, so that day and night will not come at their appointed time,
21 then also my covenant with David my servant may be broken, so that he shall not have a son to reign on his throne, and my covenant with the Levitical priests my ministers.
22 As the host of heaven cannot be numbered and the sands of the sea cannot be measured, so I will multiply the offspring of David my servant, and the Levitical priests who minister to me.”

Ezekiel 44:15-31: 15 But the Levitical priests, the sons of Zadok, who kept the charge of my sanctuary when the people of Israel went astray from me, shall come near to me to minister to me. And they shall stand before me to offer me the fat and the blood, declares the Lord God.
16 They shall enter my sanctuary, and they shall approach my table, to minister to me, and they shall keep my charge.
17 And when they enter the gates of the inner court, they shall wear linen garments. They shall have nothing of wool on them, while they minister at the gates of the inner court, and within.
18 They shall have linen turbans on their heads, and linen undergarments around their waists. They shall not bind themselves with anything that causes sweat.
19 And when they go out into the outer court to the people, they shall put off the garments in which they have been ministering and lay them in the holy chambers.
20 They shall not shave their heads or let their locks grow long; they shall surely trim the hair of their heads.

24 In a dispute, they shall act as judges, and they shall judge it according to my judgments. They shall keep my laws and my statutes in all my appointed feasts, and they shall keep my Sabbaths holy.

29 They shall eat the grain offering, the sin offering, and the guilt offering, and every devoted thing in Israel shall be theirs.
30 And the first of all the firstfruits of all kinds, and every offering of all kinds from all your offerings, shall belong to the priests. You shall also give to the priests the first of your dough, that a blessing may rest on your house.
31 The priests shall not eat of anything, whether bird or beast, that has died of itself or is torn by wild animals.

Malachi 2:1-9: 2 “And now, O priests, this command is for you.”
2 If you will not listen, if you will not take it to heart to give honor to my name, says the Lord of hosts, then I will send the curse upon you and I will curse your blessings. Indeed, I have already cursed them, because you do not lay it to heart.
3 Behold, I will rebuke your offspring, and spread dung on your faces, the dung of your offerings, and you shall be taken away with it.
4 So shall you know that I have sent this command to you, that my covenant with Levi may stand, says the Lord of hosts.
5 “My covenant with him was one of life and peace, and I gave them to him. It was a covenant of fear, and he feared me. He stood in awe of my name.”
6 True instruction was in his mouth, and no wrong was found on his lips. He walked with me in peace and uprightness, and he turned many from iniquity.
7 For the lips of a priest should guard knowledge, and people should seek instruction from his mouth, for he is the messenger of the Lord of hosts.
8 But you have turned aside from the way. You have caused many to stumble by your instruction. You have corrupted the covenant of Levi, says the Lord of hosts,
9 “Therefore I make you despised and abased before all the people, inasmuch as you do not keep my ways but show partiality in your instruction.”

Hebrews 5:1-10: 1 For every high priest chosen from among men is appointed to act on behalf of men in relation to God, to offer gifts and sacrifices for sins.
2 He can deal gently with the ignorant and wayward, since he himself is beset with weakness.
3 Because of this he is obligated to offer sacrifice for his own sins just as he does for those of the people.
4 And no one takes this honor for himself, but only when called by God, just as Aaron was.
5 So also Christ did not exalt himself to be made a high priest, but was appointed by him who said to him, “You are my Son, today I have begotten you”;
6 as he says also in another place, “You are a priest forever, after the order of Melchizedek.”
7 In the days of his flesh, Jesus offered up prayers and supplications, with loud cries and tears, to him who was able to save him from death, and he was heard because of his reverence.
8 Although he was a son, he learned obedience through what he suffered.
9 And being made perfect, he became the source of eternal salvation to all who obey him,
10 being designated by God a high priest after the order of Melchizedek.

Hebrews 7:1-28: 1 For this Melchizedek, king of Salem, priest of the Most High God, met Abraham returning from the slaughter of the kings and blessed him,
2 and to him Abraham apportioned a tenth part of everything. He is first, by translation of his name, king of righteousness, and then he is also king of Salem, that is, king of peace.
3 He is without father or mother or genealogy, having neither beginning of days nor end of life, but resembling the Son of God he continues a priest forever.
4 See how great this man was to whom Abraham the patriarch gave a tenth of the spoils!
5 And those descendants of Levi who receive the priestly office have a commandment in the law to take tithes from the people, that is, from their brothers, though these also are descended from Abraham.
6 But this man who does not have his descent from them received tithes from Abraham and blessed him who had the promises.
7 It is beyond dispute that the inferior is blessed by the superior.
8 In the one case tithes are received by mortal men, but in the other case, by one of whom it is testified that he lives.
9 One might even say that Levi himself, who receives tithes, paid tithes through Abraham,
10 for he was still in the loins of his ancestor when Melchizedek met him.
11 Now if perfection had been attainable through the Levitical priesthood (for under it the people received the law), what further need would there have been for another priest to arise after the order of Melchizedek, rather than one named after the order of Aaron?
12 For when there is a change in the priesthood, there is necessarily a change in the law as well.
13 For the one of whom these things are spoken belonged to another tribe, from which no one has ever served at the altar.
14 For it is evident that our Lord was descended from Judah, and in connection with that tribe Moses said nothing about priests.
15 This becomes even more evident when another priest arises in the likeness of Melchizedek,
16 who has become a priest, not on the basis of a legal requirement concerning bodily descent, but by the power of an indestructible life.
17 For it is witnessed of him, “You are a priest forever, after the order of Melchizedek.”
18 For on the one hand, a former commandment is set aside because of its weakness and uselessness,
19 (for the law made nothing perfect); but on the other hand, a better hope is introduced, through which we draw near to God.
20 And it was not without an oath. For those who formerly became priests were made such without an oath,
21 but this one was made a priest with an oath by the one who said to him: “The Lord has sworn and will not change his mind, ‘You are a priest forever.’”
22 This makes Jesus the guarantor of a better covenant.
23 The former priests were many in number, because they were prevented by death from continuing in office,
24 but he holds his priesthood permanently, because he continues forever.
25 Consequently, he is able to save to the uttermost those who draw near to God through him, since he always lives to make intercession for them.
26 For it was indeed fitting that we should have such a high priest, holy, innocent, unstained, separated from sinners, and exalted above the heavens.
27 He has no need, like those high priests, to offer sacrifices daily, first for his own sins and then for those of the people, since he did this once for all when he offered up himself.
28 For the law appoints men in their weakness as high priests, but the word of the oath, which came later than the law, appoints a Son who has been made perfect forever.

1 Peter 2:4-10: 4 As you come to him, a living stone rejected by men but in the sight of God chosen and precious,
5 you yourselves like living stones are being built up as a spiritual house, to be a holy priesthood, to offer spiritual sacrifices acceptable to God through Jesus Christ.
6 For it stands in Scripture: “Behold, I am laying in Zion a stone, a cornerstone chosen and precious, and whoever believes in him will not be put to shame.”
7 So the honor is for you who believe, but for those who do not believe, “The stone that the builders rejected has become the cornerstone,”
8 and “A stone of stumbling, and a rock of offense.” They stumble because they disobey the word, as they were destined to do.
9 But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light.
10 Once you were not a people, but now you are God’s people; once you had not received mercy, but now you have received mercy.

Revelation 1:5-6: 5 and from Jesus Christ the faithful witness, the firstborn of the dead, and the ruler of kings on earth. To him who loves us and has freed us from our sins by his blood.
6 and made us a kingdom, priests to his God and Father, to him be glory and dominion forever and ever. Amen.

Revelation 5:9-10: 9 And they sang a new song, saying, “Worthy are you to take the scroll and to open its seals, for you were slain, and by your blood you ransomed people for God from every tribe and language and people and nation,
10 and you have made them a kingdom and priests to our God, and they shall reign on the earth.”
