Genesis 29:30-35

So Jacob consummated his marriage and lived with Rachel [as his wife], and he loved Rachel more than Leah, and he served with Laban for another seven years. Now when the LORD saw that Leah was unloved, He made her able to bear children, but Rachel was barren. Leah conceived and gave birth to a son and named him Reuben (See, a son!), for she said, “Because the LORD has seen my humiliation and suffering; now my husband will love me [since I have given him a son].” Then she conceived again and gave birth to a son and said, “Because the LORD heard that I am unloved, He has given me this son also.” So she named him Simeon (God hears). She conceived again and gave birth to a son and said, “Now this time my husband will become attached to me [as a companion], for I have given him three sons.” Therefore he was named Levi. Again she conceived and gave birth to a [fourth] son, and she said, “Now I will praise the LORD.” So she named him Judah; then [for a time] she stopped bearing [children].
