Genesis 30:7-9

Darby Translation

⁷ And Bilhah Rachel's maidservant again conceived, and bore Jacob a second son.

⁸ And Rachel said, Wrestlings of God have I wrestled with my sister, and have prevailed; and she called his name Naphtali.

⁹ And when Leah saw that she had ceased to bear, she took Zilpah her maidservant and gave her to Jacob as wife.
