What does Genesis 29-30 really mean?

²⁹ Then Jacob went on his journey and came to the land of the people of the east.
² He looked, and behold, there was a well in the field, and behold, there were three flocks of sheep lying beside it, for out of that well the flocks were watered. The stone on the well’s mouth was large,
³ And when all the flocks were gathered there, the shepherds would roll the stone from the mouth of the well and water the sheep, and put the stone back in its place over the mouth of the well.
⁴ Jacob said to them, “My brothers, where do you come from?” They said, “We are from Haran.”
⁵ He said to them, “Do you know Laban the son of Nahor?” They said, “We know him.”
⁶ He said to them, “Is it well with him?” They said, “It is well; and see, Rachel his daughter is coming with the sheep!”
⁷ He said, “Behold, it is still high day; it is not time for the livestock to be gathered together. Water the sheep and go, pasture them.”
⁸ But they said, “We cannot, until all the flocks are gathered together and the stone is rolled from the mouth of the well; then we water the sheep.”
⁹ While he was still speaking with them, Rachel came with her father’s sheep, for she was a shepherdess.
¹⁰ Now as soon as Jacob saw Rachel the daughter of Laban his mother’s brother, and the sheep of Laban his mother’s brother, Jacob came near and rolled the stone from the well’s mouth and watered the flock of Laban his mother’s brother.
¹¹ Then Jacob kissed Rachel and wept aloud.
¹² And Jacob told Rachel that he was her father’s kinsman, and that he was Rebekah’s son, and she ran and told her father.
¹³ As soon as Laban heard the news about Jacob, his sister’s son, he ran to meet him and embraced him and kissed him and brought him to his house.
¹⁴ and Laban said to him, “Surely you are my bone and my flesh!” And he stayed with him a month.
²⁹ Then Laban said to Jacob, “Because you are my kinsman, should you therefore serve me for nothing? Tell me, what shall your wages be?”
¹⁶ Now Laban had two daughters. The name of the older was Leah, and the name of the younger was Rachel.
¹⁷ Leah’s eyes were weak, but Rachel was beautiful in form and appearance.
¹⁸ Jacob loved Rachel.
¹⁹ Laban said, “It is better that I give her to you than that I should give her to any other man; stay with me.”
²⁰ So Jacob served seven years for Rachel, and they seemed to him but a few days because of the love he had for her.
²¹ Then Jacob said to Laban, “Give me my wife that I may go in to her, for my time is completed.”
²² So Laban gathered together all the people of the place and made a feast.
²³ But in the evening he took his daughter Leah and brought her to Jacob, and he went in to her.
²⁴ Laban gave his female servant Bilhah to his daughter Rachel to be her servant.
²⁵ And in the morning, behold, it was Leah! And Jacob said to Laban, “What is this you have done to me? Did I not serve with you for Rachel? Why then have you deceived me?”
²⁶ Laban said, “It is not so done in our country, to give the younger before the firstborn.
²⁷ Complete the week of this one, and we will give you the other also in return for the service which you shall serve with me for another seven years.”
²⁸ Jacob did so, and completed her week. Then Laban gave him his daughter Rachel to be his wife.
²⁹ Laban gave his female servant Bilhah to his daughter Rachel to be her servant.
³⁰ So Jacob went in to Rachel also, and he loved Rachel more than Leah, and served Laban for another seven years.
³¹ When the Lord saw that Leah was hated, he opened her womb, but Rachel was barren.
³² And Leah conceived and bore a son, and she called his name Reuben, for she said, “Because the Lord has looked upon my affliction; for now my husband will love me.”
³³ She conceived again and bore a son, and said, “Because the Lord has heard that I am hated, he has given me this son also.” And she called his name Simeon.
³⁴ Again she conceived and bore a son, and said, “Now this time my husband will be attached to me, because I have borne him three sons.” Therefore his name was called Levi.
³⁵ And she conceived again and bore a son, and said, “This time I will praise the Lord.” Therefore she called his name Judah. Then she ceased bearing.
¹ When Rachel saw that she bore Jacob no children, she envied her sister.
² Jacob’s anger was kindled against Rachel, and he said, “Am I in the place of God, who has withheld from you the fruit of the womb?”
³ Then she said, “Here is my servant Bilhah; go in to her, so that she may give birth on my behalf, that even I may have children through her.”
⁴ So she gave him her servant Bilhah as a wife, and Jacob went in to her.
⁵ And Bilhah conceived and bore Jacob a son.
⁶ Then Rachel said, “God has judged me, and has also heard my voice and given me a son.” Therefore she called his name Dan.
⁷ And Rachel’s servant Bilhah conceived again and bore Jacob a second son.
⁸ Then Rachel said, “With mighty wrestlings I have wrestled with my sister and have prevailed.” So she called his name Naphtali.
⁹ When Leah saw that she had ceased bearing children, she took her servant Zilpah and gave her to Jacob as a wife.
¹⁰ Leah’s servant Zilpah bore Jacob a son.
¹¹ Then Leah said, “Good fortune has come!” So she called his name Gad.
¹² Leah’s servant Zilpah bore Jacob a second son.
¹³ And Leah said, “Happy am I! For women have called me happy.” So she called his name Asher.
¹⁴ In the days of wheat harvest Reuben went and found mandrakes in the field and brought them to his mother Leah. Then Rachel said to Leah, “Please give me some of your son’s mandrakes.”
¹⁵ But she said to her, “Is it a small matter that you have taken away my husband? Would you take away my son’s mandrakes also?” So Rachel said, “Then he may lie with you tonight in exchange for your son’s mandrakes.”
¹⁶ When Jacob came from the field in the evening, Leah went out to meet him and said, “You must come in to me, for I have hired you with my son’s mandrakes.” So he lay with her that night.
¹⁷ And God listened to Leah, and she conceived and bore Jacob a fifth son.
¹⁸ So Leah said, “God has given me my wages because I gave my servant to my husband.” So she called his name Issachar.
¹⁹ Leah conceived again, and she bore Jacob a sixth son.
²⁰ Then Leah said, “God has endowed me with a good endowment; now my husband will honor me, because I have borne him six sons.” So she called his name Zebulun.
²¹ Afterward she bore a daughter and called her name Dinah.
²² Then God remembered Rachel, and God listened to her and opened her womb.
²³ She conceived and bore a son and said, “God has taken away my reproach.”
²⁴ And she called his name Joseph, saying, “May the Lord add to me another son!”
²⁵ As soon as Rachel had borne Joseph, Jacob said to Laban, “Send me away, that I may go to my own home and country.
²⁶ Give me my wives and my children for whom I have served you, that I may go, for you know the service that I have given you.
²⁷ But Laban said to him, “If I have found favor in your sight, I have learned by divination that the Lord has blessed me because of you.”
²⁸ And he said, “Name your wages, and I will give it.”
²⁹ He said to him, “You yourself know how I have served you, and how your livestock has fared with me.
³⁰ For you had little before I came, and it has increased abundantly, and the Lord has blessed you wherever I turned. But now when shall I provide for my own household also?”
³¹ He said, “What shall I give you?” Jacob said, “You shall not give me anything. If you will do this for me, I will again pasture your flock and keep it.
³² Let me pass through all your flock today, removing from it every speckled and spotted sheep and every black lamb, and the spotted and speckled among the goats, and they shall be my wages.
³³ So my honesty will answer for me later, when you come to look into my wages with you. Every one that is not speckled and spotted among the goats and black among the lambs, if found with me, shall be counted stolen.”
³⁴ But Laban said, “Behold, let it be according to your word.”
³⁵ But that day Laban removed the male goats that were striped and spotted, and all the female goats that were speckled and spotted, every one that had white on it, and every lamb that was black, and put them in the charge of his sons.
³⁶ Then he put a distance of three days’ journey between himself and Jacob, and Jacob pastured the rest of Laban’s flock.
³⁷ Then Jacob took fresh sticks of poplar and almond and plane trees, and peeled white streaks in them, exposing the white of the sticks.
³⁸ And he set the sticks that he had peeled in front of the flocks in the troughs, that is, the watering places, where the flocks came to drink. And since they bred when they came to drink,
³⁹ The flocks bred in front of the sticks and thus brought forth striped, speckled, and spotted.
⁴⁰ Jacob separated the lambs and set the faces of the flocks toward the striped and all the black in the flock of Laban. He put his own droves apart and did not put them with Laban’s flock.
⁴¹ Whenever the stronger of the flock were breeding, Jacob would lay the sticks in the troughs before the eyes of the flock, that they might breed among the sticks,
⁴² But when the flock were feeble, he did not put them in. So the feebler would be Laban’s, and the stronger Jacob’s.
⁴³ Thus the man increased greatly and had large flocks, female servants and male servants, and camels and donkeys.
