Genesis 30:7-9

Young's Literal Translation

⁷ And Bilhah, Rachel's maid-servant, conceiveth again, and beareth a second son to Jacob,

⁸ and Rachel saith, `With wrestlings of God I have wrestled with my sister, yea, I have prevailed;' and she calleth his name Napthali.

⁹ And Leah seeth that she hath ceased from bearing, and she taketh Zilpah her maid-servant, and giveth her to Jacob for a wife;
