Genesis 30:4

²  And Jacob's anger was kindled against Rachel: and he said, Am I in God's stead, who hath withheld from thee the fruit of the womb?

³  And she said, Behold my maid Bilhah, go in unto her; and she shall bear upon my knees, that I may also have children by her.

⁴  And she gave him Bilhah her handmaid to wife: and Jacob went in unto her.

⁵  And Bilhah conceived, and bare Jacob a son.

⁶  And Rachel said, God hath judged me, and hath also heard my voice, and hath given me a son: therefore called she his name Dan.
