But we see an even deeper work with Leah, Rachel, Jacob and Joseph
Leah was unloved
31 When the Lord saw that Leah was unloved, He opened her womb; but Rachel was barren. 32 So Leah conceived and bore a son, and she called his name Reuben; for she said, “The Lord has surely looked on my affliction. Now therefore, my husband will love me.”
If you read this story it seems there is no hint of sin from Leah. She had nothing to do with deceiving Jacob, this was her father's doing, and she desperately wanted to be loved by Jacob. So then how do you explain this, what is the sin that she needs to forgive so that God could forgive her? Read on!
God opened Leah's womb to have kids while at the same time making it so that Rachel did not bear any children. So this struggle begins, Rachel gives her maid to Jacob who bears two children, and Leah gives her maid to Jacob who also bears two children. And Leah had four children at this point. There are 8 babies running around, Reuben is the oldest, maybe six years old at this point, and Rachel has no children.
14 Now Reuben went in the days of wheat harvest 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?” And Rachel said, “Therefore he will lie with you tonight for your son’s mandrakes.”
Reuben goes out and picks some wildflowers for his mom. Rachel sees this, the aunt without any kids, and she asks Leah if she could have those flowers. Rachel has changed her attitude. Instead of competing with her sister, she decides she wants to be part of the family, to enjoy all the kids. She isn't the mother but she is the aunt. Instead of being jealous about what she doesn't have she wants to celebrate what she does have. This is when we discover Leah's unforgiveness in her heart. She married Jacob with "deceit" that made things hard enough, but then her sister comes and marries her husband a week later. Imagine how hard that would be in a normal marriage, but to be unloved because Jacob had been cheated and then Rachel comes and takes him away from her. So Rachel for the first time sees what happened through her sister's eyes. Leah had nothing to do with this, it was Laban, she is the victim. So she makes a deal with her sister, you let me be the loving aunt for your children and in exchange you get Jacob for the night. It sounds crass, but remember what happened, Jacob worked for 7 years to get Rachel and then was cheated. Now Leah can replay the wedding night without any deceit, she has bought him. The sin that Leah needed to be forgiven of is her unforgiveness to Rachel. As a result Rachel was "unloved", an aunt shunned from the family. As a result of Rachel having her heart enlarged to see that she could enjoy all the children and the whole family. Her heart embraced all the children as her own.
After this the situation in the family was restored. Leah was loved, Jacob chose to be buried alongside Leah and Rachel became the mother of all Israel. Rachel is considered the Mother of Israel.
Jacob had his wages changed ten times
38 These twenty years I have been with you; your ewes and your female goats have not miscarried their young, and I have not eaten the rams of your flock. 39 That which was torn by beasts I did not bring to you; I bore the loss of it. You required it from my hand, whether stolen by day or stolen by night. 40 There I was! In the day the drought consumed me, and the frost by night, and my sleep departed from my eyes. 41 Thus I have been in your house twenty years; I served you fourteen years for your two daughters, and six years for your flock, and you have changed my wages ten times. 42 Unless the God of my father, the God of Abraham and the Fear of Isaac, had been with me, surely now you would have sent me away empty-handed. God has seen my affliction and the labor of my hands, and rebuked you last night.”
If you read the story there is no sin from Jacob and yet Laban changed his wages ten times and it was a real affliction that God was aware of. Or was there?
Let's forgive Laban, what do we see? We learn that Jacob has discovered how to breed various traits into animals. If Laban changes the contract so that he gets all the sheep that are this or that coat then Jacob adjusts the breeding so that is what he gets. Changing this ten times was like running a science experiment over and over again to prove you have control of this and can determine what traits you want bred into the animals.
OK, so what sin of Jacob does God now forgive? Jacob had been given a dream of angels ascending and descending on a ladder to heaven to get treasures from heaven. Understanding genetics and how to breed various traits is one of the great treasures of all human history and certainly a great treasure to pass down to your children who are also shepherds. Where is Jacob's worship and praise? We see a grudging acknowledgement that God had "seen" his affliction. With Hagar God heard her complaints, but here God "sees" his affliction. This is like those who fast and make sure they "appear to be fasting". Jesus called them hypocrites. We are all cut from the same block of cheese and unless we see our sin and forgive others we will not be healed from this.
Joseph was hated and betrayed
52 And the name of the second he called Ephraim: “For God has caused me to be fruitful in the land of my affliction.”
We should all know the story, sold into slavery by his brothers and then framed by his boss's wife and sent to prison. You would think that he would be a very angry, bitter old man. But instead he tells his brothers that these things were "God's doing".
Genesis 45:5 But now, do not therefore be grieved or angry with yourselves because you sold me here; for God sent me before you to preserve life.
He was mistreated worse than Hagar was. He was unloved worse than Leah was. And he was mistreated by his boss worse than Jacob was. But he had a vision, he saw that God was working all things to good for those who love God and are called according to purpose. He made sure no one heard him complaining which is why the guards appreciated him so much and he made sure no one saw him "fasting" which is why he cleaned up before going to Pharaoh. He also saw that he had received a double blessing.
Clearly he forgave his brothers and his former boss. He saw they were merely tools used by God to accomplish His purpose which was the salvation of mankind.
