Hagar and Ishmael
1 Now Abram’s wife Sarai had borne him no children, but she had an Egyptian maidservant named Hagar. 2 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. 3 So 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.
