Genesis 30:1-3

1When Rachel saw that she was not bearing Jacob any children, she became jealous of her sister. So she said to Jacob, “Give me children, or I’ll die!”

2Jacob became angry with her and said, “Am I in the place of God, who has kept you from having children?”

3Then she said, “Here is Bilhah, my servant. Sleep with her so that she can bear children for me and I too can build a family through her.”
