Deuteronomy 20 Explained – Verse by Verse Commentary

1 When you go out to war against your enemies, and see horses and chariots and an army larger than your own, you shall not be afraid of them, for the Lord your God is with you, who brought you up out of the land of Egypt.
2 and shall say to them, ‘Hear, O Israel, today you are drawing near for battle against your enemies: let not your heart faint. Do not fear or panic or be in dread of them,
3 and shall say to them, ‘Hear, O Israel, today you are drawing near for battle against your enemies: let not your heart faint. Do not fear or panic or be in dread of them,
4 for the Lord your God is he who goes with you to fight for you against your enemies, to give you the victory.
5 Then the officers shall speak to the people, saying, ‘Is there any man who has built a new house and has not dedicated it? Let him go back to his house, lest he die in the battle and another man dedicate it.
6 And what man is there who has planted a vineyard and has not enjoyed its fruit? Let him go back to his house, lest he die in the battle and another man enjoy its fruit.
7 And is there any man who has betrothed a wife and has not taken her? Let him go back to his house, lest he die in the battle and another man take her.’
8 And the officers shall speak further to the people, and say, ‘Is there any man who is fearful and fainthearted? Let him go back to his house, lest he make the heart of his fellows melt like his own.’
9 And when the officers have finished speaking to the people, then commanders shall be appointed at the head of the people.
10 “When you draw near to a city to fight against it, offer terms of peace to it.”
11 And if it responds to you peaceably and it opens to you, then all the people who are found in it shall do forced labor for you and shall serve you.
12 And if it will make no peace with you, but makes war against you, then you shall besiege it.
13 And when the Lord your God gives it into your hand, you shall put all its males to the sword,
14 but the women and the little ones, the livestock, and everything else in the city, all its spoil, you shall take as plunder for yourselves. And you shall enjoy the spoil of your enemies, which the Lord your God has given you.
15 Thus you shall do to all the cities that are very far from you, which are not cities of the nations here.
16 But in the cities of these peoples that the Lord your God is giving you for an inheritance, you shall save alive nothing that breathes,
17 but you shall devote them to complete destruction, the Hittites and the Amorites, the Canaanites and the Perizzites, the Hivites and the Jebusites, as the Lord your God has commanded,
18 that they may not teach you to do according to all their abominable practices that they have done for their gods, and so you sin against the Lord your God.
19 “When you besiege a city for a long time, making war against it in order to take it, you shall not destroy its trees by wielding an axe against them. You may eat from them, but you shall not cut them down. Are the trees in the field human, that they should be besieged by you?
20 Only the trees that you know are not trees for food you may destroy and cut down, that you may build siegeworks against the city that makes war with you, until it falls.

The True Meaning of Deuteronomy 20

The book of Deuteronomy was written by Moses, the great prophet and leader of the Israelites. Moses provided the people with a series of laws and instructions to guide them in their new home as they prepared to enter the Promised Land. Moses addresses the Israelites regarding the conduct of war in this chapter. He reminds them that their battles are not merely physical, but spiritual, as they fight to claim the land that God has promised them. The chapter outlines the protocols for warfare, including exemptions from military service and the treatment of conquered cities.

We see echoes of earlier biblical accounts, such as the Israelites’ exodus from Egypt and their victories over the Amalekites. Moses emphasizes that the Lord will be with them in their battles, and that their success depends on their obedience to His commands. This foreshadows the challenges the Israelites will face as they seek to conquer the land and establish their kingdom. This passage reminds the Israelites that their true strength lies not in their own might, but in their unwavering faith in the God who has brought them this far as they stand on the cusp of a new chapter in their history. The lessons of Deuteronomy 20 will be crucial as they navigate the trials and tribulations that lie ahead.

Deuteronomy 20:1-4

The passage in Deuteronomy 20:1-4 addresses the Israelites regarding the attitude they should have going into battle. Let’s break down these verses into important sections for a more thorough understanding.

Verse 1 opens with the command not to be afraid when going out to battle against their enemies. This instruction is not just about physical courage but also about placing their trust in the Lord. It is a reminder that with God on their side, no enemy is too formidable for them to face. The message here is clear: trust in the Lord’s strength rather than giving in to fear.

Verse 2 introduces the priest who is to address the soldiers, reminding them of the reassurance and encouragement that come from having a spiritual leader in their midst. The presence of the priest serves to remind the troops of their faith and the importance of God’s guidance even in the heat of battle. Through the priest, the soldiers are being reminded of their spiritual duty and that their actions in battle should be in accordance with God’s will.

Verse 3 sets out the conditions for exemption from battle, including various scenarios such as building a new house, planting a vineyard, or being afraid. These exemptions convey a message of compassion and understanding, illustrating that God values the well-being of His people. It also emphasizes the need for discernment and practical considerations in matters of conflict.

Verse 4 brings attention to the importance of having a heart that is undivided in battle. This unity of purpose and focus on the task at hand is crucial for success in warfare. The passage highlights the significance of commitment and determination in the face of challenges by emphasizing the need for undivided dedication. These verses reflect a recurring theme in the Bible regarding the importance of faith, trust, and obedience to God’s commands when examined within the broader context of Deuteronomy 20. The passage underscores the idea that victory in battles, whether physical or spiritual, comes from relying on God’s strength rather than human capabilities alone. It also stresses the need for unity, discernment, and unwavering dedication in times of conflict.

Looking at other verses in the Bible, we can draw parallels to similar messages of trust in the Lord during times of struggle. Psalm 27:1 says, “The Lord is my light and my salvation—whom shall I fear?”. The Lord is the stronghold of my life—of whom shall I be afraid?” This verse echoes the sentiment in Deuteronomy 20, emphasizing the need for faith and trust in God’s protection. Deuteronomy 20:1-4 serves as a reminder to trust in God’s strength, seek spiritual guidance, show compassion, and maintain unwavering dedication in all endeavors, including battles both physical and spiritual.

Deuteronomy 20:5-9

The verses in Deuteronomy 20:5-9 outline instructions for the Israelites when preparing for battle. Let’s break these verses down step by step to understand their significance in the broader context of the Bible. The instruction in verse 5 gives the officers who are in charge of leading the soldiers into battle. They are told to address the troops and encourage them by reminding them of their faith and purpose, emphasizing the importance of not being fearful or fainthearted. This message is meant to remind the soldiers that they have the strength and courage given by God to face their enemies, and that they should trust in Him rather than give in to their fears. This theme of trusting in God’s strength and guidance is a recurring message throughout the Bible. Psalm 27:1 says, “The Lord is my light and my salvation—whom shall I fear?”. The Lord is the stronghold of my life—of whom shall I be afraid?”

Verse 6 mentions certain exemptions from military service. Those who have recently built a new house, planted a vineyard, or become engaged to be married are excused from going to war. This provision shows an understanding of human needs and responsibilities outside of the battlefield. It also reflects the importance of family and home life in the Israelite community. Allowing these exemptions not only acknowledges the significance of these life events but also ensures that those who are engaged in them can fully focus on their new responsibilities. This is a demonstration of God’s care for His people’s well-being and serves as a reminder that there are times when personal duties and obligations take precedence over other tasks.

Verses 7 and 8 instruct that those exempt from going to war should return home, so as not to discourage their fellow Israelites who are preparing for battle. This shows a sense of solidarity and support within the community. It highlights the importance of maintaining morale and unity among the soldiers, as these factors are crucial in times of conflict. It reminds us of the value of teamwork and cooperation, as mentioned in Ecclesiastes 4:9-10, which says, “Two are better than one, because they have a good return for their labor: If either of them falls down, one can help the other up. But pity anyone who falls and has no one to help them up.”

Lastly, in verse 9, the officers are instructed to appoint leaders to continue with the encouragement and validation before the troops. This delegation of authority reveals the wise leadership structure implemented within the Israelite army. It ensures that there is a chain of command and that communication of important messages is effectively passed down to all levels of the army. This organized approach to leadership reflects the importance of order and discipline in achieving success, not only in battle but also in various aspects of life. This concept of leadership and delegation can be seen in the New Testament as well, in passages like 1 Timothy 5:17, which says, “The elders who direct the affairs of the church well are worthy of double honor, especially those whose work is preaching and teaching. These verses in Deuteronomy 20:5-9 provide practical guidance for the Israelites in times of war, emphasizing the importance of faith, unity, and leadership. The principles outlined here are timeless and can be applied to various situations where courage, support, and effective leadership are needed. They serve as a reminder of God’s provision, the strength found in community, and the wisdom of organized leadership structures.

Deuteronomy 20:10-15

God gives the Israelites a set of instructions concerning warfare in Deuteronomy 20:10-15 through Moses. The section begins by stating that when the Israelites approach a city to fight against it, they are to first offer terms of peace to that city. If the city accepts the terms and opens its gates, then all the people in it shall serve the Israelites in forced labor. However, if the city does not accept the terms of peace and instead chooses to fight, the Israelites are to besiege the city. Once the city falls into their hands, the Israelites are to put all the men to the sword but take the women, children, livestock, and everything else in the city as plunder.

This passage is challenging for many contemporary readers due to the apparent harshness of the commands regarding warfare. It is crucial to understand this passage in its historical and cultural context. Warfare in the ancient Near East was a brutal reality, and the rules of engagement were often merciless. God’s instructions to the Israelites were not endorsing senseless violence but establishing order, boundaries, and justice within the framework of the society at that time. God demonstrates His mercy and desire for reconciliation even in the context of conflict by offering terms of peace before attacking. The opportunity for peace reflects God’s desire for His people to seek peaceful resolutions before resorting to violence. However, if the enemy refuses peace and forces the Israelites to defend themselves, God ensures that justice is carried out by giving the Israelites victory over their enemies.

This passage also reveals God’s sovereignty and power over all nations. The cities and people that the Israelites face in battle are ultimately under God’s control, and He uses the Israelites as His instrument of judgment upon those who rebel against Him. The plunder taken from the defeated city serves as a reminder of God’s provision for His people and His fulfillment of His promises to them.

Throughout the Bible, there are instances where God commands the Israelites to engage in warfare as a means of judgment or establishing His authority. Joshua led the Israelites in conquering the Promised Land by following God’s instructions to defeat the Canaanite nations. These conquests were not driven by a desire for power or conquest but by God’s plan to fulfill His covenant with Abraham and establish His people in the land He had promised them. The commands regarding warfare in Deuteronomy 20 may be difficult to reconcile with our modern sensibilities, but they serve as a reminder of God’s justice, sovereignty, and mercy. It calls us to trust in God’s ultimate plan and purpose, even in situations of conflict and struggle.

Deuteronomy 20:16-18

God commanded the Israelites to devote the nations in the Promised Land to complete destruction, including the Hittites, Amorites, Canaanites, Perizzites, Hivites, and Jebusites, so that they may not teach the Israelites their abominable practices.”

This command may seem harsh and difficult to grasp from a modern perspective, but it needs to be understood in the historical and theological context of the time. The nations mentioned – the Hittites, Amorites, Canaanites, Perizzites, Hivites, and Jebusites – were known for their immoral and idolatrous practices. God was concerned that if the Israelites allowed these nations to remain, they would be led astray into worshiping false gods and participating in wicked practices. Therefore, the command to utterly destroy these nations was not about ethnic cleansing but about preserving the spiritual integrity of the Israelites.

This passage highlights the importance of remaining faithful to God and avoiding idolatry. Throughout the Bible, idolatry is consistently condemned as a grave sin that leads to destruction. The Israelites were repeatedly warned against worshiping other gods and mixing their worship practices with those of the pagan nations around them. The consequences of idolatry are seen in the stories of the Israelites when they strayed from God, faced God’s discipline, and often fell into the hands of their enemies. This passage in the broader context of the Bible foreshadows the ongoing spiritual battle between the people of God and the forces of evil. It serves as a reminder that believers need to be vigilant against anything that might lead them away from God. The New Testament also emphasizes the importance of spiritual warfare and the need to put on the full armor of God to stand against the schemes of the devil (Ephesians 6:10-18).

While the command to utterly destroy these nations may be difficult to reconcile with a loving and merciful God, it ultimately underscores the seriousness of sin and the importance of staying true to God’s commands. God’s desire was not to harm these nations for the sake of it but to protect His people from the corrupting influence of idolatry and ensure their faithfulness to Him.

Deuteronomy 20:19-20

The Lord instructs the Israelites, through Moses, in Deuteronomy 20:19-20, not to destroy the trees of a city they lay siege to by wielding an ax against them. Armies in ancient times commonly cut down the surrounding trees in warfare to deprive the city of resources, use the wood for siege equipment, or simply retaliate. However, the Lord emphasizes the importance of preserving the trees, even in times of conflict, by commanding the people to eat from them and not to cut them down.

This commandment reflects God’s concern for creation and sustainable practices, showing the Israelites that even in the midst of war, they are to demonstrate respect and stewardship for the environment. It also serves as a reminder that the earth and its resources ultimately belong to God, and humans are called to be good stewards of His creation. This directive teaches a valuable lesson about responsible and ethical behavior, even in times of struggle or conflict.

The significance of preserving the trees holds broader implications for humanity’s relationship with the environment. Throughout the Bible, we can see God’s overarching care for His creation in a larger context. God commands Adam to care for the Garden of Eden in Genesis 2:15, establishing the principle of stewardship over the earth. Psalm 24:1 also declares, “The earth is the Lord’s, and everything in it, the world, and all who live in it.” This reaffirms the idea that humans are entrusted with the care of God’s creation and are called to act responsibly towards it.

Furthermore, the idea of not destroying the trees during war can also be seen as a symbol of hope and restoration. Trees have often represented life, growth, and the presence of God throughout the Bible. Trees planted by streams of water yield fruit in season, comparing the righteous in Psalm 1:3. This imagery reinforces the idea that preserving the trees even in times of conflict can symbolize the hope for peace, renewal, and the potential for new life to emerge after times of struggle. The command to spare the trees in war not only has practical implications for sustainability but also carries deeper spiritual and symbolic meanings within the biblical narrative.

After Deuteronomy 20

The Israelites had been given clear instructions on how to wage war against their enemies. They were to show no mercy to the inhabitants of the Promised Land, for the Lord had commanded their destruction. However, the Israelites were also to offer terms of peace to distant cities before attacking them. If the city surrendered, the people were to be spared and made to serve as forced laborers. Only if the city refused to surrender could the Israelites lay siege to it and destroy it completely. The Israelites knew that difficult battles lay ahead as they prepared to cross the Jordan River and enter the land of Canaan. But the Lord had promised to go before them and give them victory, if they remained faithful to His commands. With this assurance, the Israelites set out, ready to claim the land that God had sworn to their ancestors.
