Genesis 30:7-9

King James Version

⁷ And Bilhah Rachel's maid conceived again, and bare Jacob a second son.

⁸ And Rachel said, With great wrestlings have I wrestled with my sister, and I have prevailed: and she called his name Naphtali.

⁹ When Leah saw that she had left bearing, she took Zilpah her maid, and gave her Jacob to wife.
