Genesis 29:30-32

29:30 Jacob had marital relations with Rachel as well. He loved Rachel more than Leah, so he worked for Laban for seven more years.

The Family of Jacob

29:31 When the Lord saw that Leah was unloved, he enabled her to become pregnant while Rachel remained childless. 29:32 So Leah became pregnant and gave birth to a son. She named him Reuben, for she said, “The Lord has looked with pity on my oppressed condition. Surely my husband will love me now.”
