Genesis 29:29-31 New Life Version (NLV)
29 Laban also took Bilhah, a woman who served him, and gave her to his daughter Rachel, to serve her. 30 So Jacob went in to Rachel also. He loved Rachel more than Leah. And he worked for Laban seven years more.
31 When the Lord saw that Leah was not loved, He made her able to give birth. But Rachel could not give birth.
