AKJV⁽ⁱ⁾ ³ And she said, Behold my maid Bilhah, go in to her; and she shall bear on my knees, that I may also have children by her. ⁴ And she gave him Bilhah her handmaid to wife: and Jacob went in to her. ⁵ And Bilhah conceived, and bore Jacob a son. ⁶ And Rachel said, God has judged me, and has also heard my voice, and has given me a son: therefore called she his name Dan. ⁷ And Bilhah Rachel's maid conceived again, and bore 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.
