Genesis 30:1-13

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. 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? 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. And she gave him Bilhah her handmaid to wife: and Jacob went in unto her. And Bilhah conceived, and bare Jacob a son. 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. And Bilhah Rachel's maid conceived again, and bare Jacob a second son. And Rachel said, With great wrestlings have I wrestled with my sister, and I have prevailed: and she called his name Naphtali. When Leah saw that she had left bearing, she took Zilpah her maid, and gave her Jacob to wife. And Zilpah Leah's maid bare Jacob a son. And Leah said, A troop cometh: and she called his name Gad. And Zilpah Leah's maid bare Jacob a second son. And Leah said, Happy am I, for the daughters will call me blessed: and she called his name Asher.
