Genesis 30:1-4 (New King James Version)

Genesis 30

 ¹ Now when Rachel saw that she bore Jacob no children, Rachel envied her sister, and said to Jacob, “Give me children, or else I die!”
² And Jacob’s anger was aroused against Rachel, and he said, “Am I in the place of God, who has withheld from you the fruit of the womb?”
³ So she said, “Here is my maid Bilhah; go in to her, and she will bear a child on my knees, that I also may have children by her.” ⁴ Then she gave him Bilhah her maid as wife, and Jacob went in to her.
