Genesis 29:30-34

30Jacob slept with Rachel too. He loved Rachel more than Leah. So he worked for Laban another seven years.

31When the Lord saw Leah was unloved, he made it possible for her to have children, but Rachel had none.

32Leah became pregnant and gave birth to a son. She named him Reuben [Here’s My Son], because she said, “Certainly, the Lord has seen my misery; now my husband will love me!”

33She became pregnant again and gave birth to another son. She said, “Certainly, the Lord has heard that I’m unloved, and he also has given me this son.” So she named him Simeon [Hearing].

34She became pregnant again and gave birth to another son. She said, “Now at last my husband will become attached to me because I’ve given him three sons.” So she named him Levi [Attached].
