Genesis 16:2-4

Revised Standard Version

² and Sar′ai said to Abram, “Behold now, the Lord has prevented me from bearing children; go in to my maid; it may be that I shall obtain children by her.” And Abram hearkened to the voice of Sar′ai. ³ So, after Abram had dwelt ten years in the land of Canaan, Sar′ai, Abram’s wife, took Hagar the Egyptian, her maid, and gave her to Abram her husband as a wife. ⁴ And he went in to Hagar, and she conceived; and when she saw that she had conceived, she looked with contempt on her mistress.
