Gen 30:1-6

1When Rachel saw that she bore Jacob no children, she envied her sister; and she said to Jacob, “Give me children, or I shall die!”2Jacob became very angry with Rachel and said, “Am I in the place of God, who has withheld from you the fruit of the womb?”3Then she said, “Here is my maid Bilhah; go in to her, that she may bear upon my knees and that I too may have children through her.”4So she gave him her maid Bilhah as a wife; and Jacob went in to her.5And Bilhah conceived and bore Jacob a son.6Then Rachel said, “God has judged me, and has also heard my voice and given me a son”; therefore she named him Dan.
