Genesis 30:7-9

New American Standard Bible

⁷ And Rachel’s slave Bilhah conceived again and bore Jacob a second son. ⁸ So Rachel said, “With ^[a]mighty wrestling I have ^[b]wrestled with my sister, and I have indeed prevailed.” And she named him Naphtali.

⁹ When Leah saw that she had stopped having children, she took her slave Zilpah and gave her to Jacob as a wife.
