2So 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.
3So after he had lived in Canaan for ten years, his wife Sarai took her Egyptian maidservant Hagar and gave her to Abram to be his wife.
