Genesis 29:31-33

31When the Lord saw that Leah was unloved, he enabled her to have children, but Rachel could not conceive.

32So Leah became pregnant and gave birth to a son. She named him Reuben, for she said, “The Lord has noticed my misery, and now my husband will love me.”

33She soon became pregnant again and gave birth to another son. She named him Simeon, for she said, “The Lord heard that I was unloved and has given me another son.”
