Isaac Is Born

21 The Lord was gracious to Sarah, just as he had said he would be. The Lord did for Sarah what he had promised to do. ² Sarah became pregnant. She had a son by Abraham when he was old. The child was born at the exact time God had promised. ³ Abraham gave the name Isaac to the son Sarah had by him. ⁴ When his son Isaac was eight days old, Abraham circumcised him. He did it exactly as God had commanded him. ⁵ Abraham was 100 years old when his son Isaac was born to him.

⁶ Sarah said, “God has given laughter to me. Everyone who hears about this will laugh with me.” ⁷ She also said, “Who would have said to Abraham that Sarah would breast-feed children? But I’ve had a son by him when he is old.”
