Genesis 21:1-7

Common English Bible

Isaac’s birth

21 The Lord was attentive to Sarah just as he had said, and the Lord carried out just what he had promised her. ² She became pregnant and gave birth to a son for Abraham when he was old, at the very time God had told him. ³ Abraham named his son—the one Sarah bore him—Isaac.^{[a] 4} Abraham circumcised his son Isaac when he was eight days old just as God had commanded him. ⁵ Abraham was 100 years old when his son Isaac was born. ⁶ Sarah said, “God has given me laughter. Everyone who hears about it will laugh with me.”^{[b] 7} She said, “Who could have told Abraham that Sarah would nurse sons? But now I’ve given birth to a son when he was old!”
