Genesis 30:3-6

BSB(i) 3 Then she said, “Here is my maidservant Bilhah. Sleep with her, that she may bear children for me, so that through her I too can build a family.” 4 So Rachel gave Jacob her servant Bilhah as a wife, and he slept with her, 5 and Bilhah conceived and bore him a son. 6 Then Rachel said, “God has vindicated me; He has heard my plea and given me a son.” So she named him Dan.
