31 When the Lord saw that Leah was unloved, he opened her womb; but Rachel was barren.

Genesis 29:31 In-Context

29 (Laban gave his maid Bilhah to his daughter Rachel to be her maid.)
30 So Jacob went in to Rachel also, and he loved Rachel more than Leah. He served Laban for another seven years.
31 When the Lord saw that Leah was unloved, he opened her womb; but Rachel was barren.
32 Leah conceived and bore a son, and she named him Reuben; for she said, "Because the Lord has looked on my affliction; surely now my husband will love me."
33 She conceived again and bore a son, and said, "Because the Lord has heard that I am hated, he has given me this son also"; and she named him Simeon.
