And Sarai said unto Abram, Behold now, the LORD hath restrained me from bearing: I pray thee, go in unto my maid; it may be that I may obtain children by her. And Abram hearkened to the voice of Sarai.

So Sarai said to Abram, “Look now, the LORD has prevented me from bearing children. Please go to my maidservant; perhaps I can build a family by her.” And Abram listened to the voice of Sarai.

And she said, Behold my maid Bilhah, go in unto her; and she shall bear upon my knees that I may also have children by her.

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.”

When Leah saw that she had left bearing, she took Zilpah her maid, and gave her Jacob to wife.

When Leah saw that she had stopped having children, she gave her servant Zilpah to Jacob as a wife.
