²² The Scriptures say that Abraham had two sons, one from his slave wife and one from his freeborn wife.^[a]

¹⁵ So Hagar gave Abram a son, and Abram named him Ishmael.

¹⁰ So she turned to Abraham and demanded, “Get rid of that slave woman and her son. He is not going to share the inheritance with my son, Isaac. I won’t have it!”

The Birth of Isaac

21 The Lord kept his word and did for Sarah exactly what he had promised. ² She became pregnant, and she gave birth to a son for Abraham in his old age. This happened at just the time God had said it would.

² So Sarai said to Abram, “The Lord has prevented me from having children. Go and sleep with my servant. Perhaps I can have children through her.” And Abram agreed with Sarai’s proposal. ³ So Sarai, Abram’s wife, took Hagar the Egyptian servant and gave her to Abram as a wife. (This happened ten years after Abram had settled in the land of Canaan.)

⁴ So Abram had sexual relations with Hagar, and she became pregnant. But when Hagar knew she was pregnant, she began to treat her mistress, Sarai, with contempt.
