When the Lord saw that Leah was hated, he opened her womb, but Rachel was barren. 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.”
The first child brought Leah vindication: God saw her pain and would perhaps legitimize her to her husband.
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.
The second child brought Leah comfort: God heard her cry and acknowledged that she was hated.
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.
The third child brought Leah a bargaining chip: God seemed to be vacant, so she fought for his attention.
And she conceived again and bore a son, and said, “This time I will praise the Lord.” Therefore she called his name Judah. (Genesis 29:31-35)
The fourth child was Leah's praise: All the vindication, comfort, and bargaining in the world can't bring the gospel to earth. She named him Judah, of the lineage of Jesus.
Rachel was loved, Leah was hated, but God brought the Lion of Judah through the loins of Leah. God doesn't waste your suffering.
