Genesis 30:1-4 King James Version (KJV)
30 And when Rachel saw that she bare Jacob no children, Rachel envied her sister; and said unto Jacob, Give me children, or else I die.
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.
