³ She said, “Here is my maid Bilhah. Go, sleep with her, and let her give birth to a child that will be laid on my knees, so that through her I too can build a family.” ⁴ So she gave him Bilhah her slave-girl as his wife, and Ya‘akov went in and slept with her. ⁵ Bilhah conceived and bore Ya‘akov a son.
