1 The Lord came to Sarah as He had said, and the Lord did for Sarah what He had promised.
2 Sarah became pregnant and bore a son to Abraham in his old age, at the appointed time God had told him.
3 Abraham named his son who was born to him — the one Sarah bore to him — Isaac.
4 When his son Isaac was eight days old, Abraham circumcised him, as God had commanded him.
5 Abraham was 100 years old when his son Isaac was born to him.
6 Sarah said, “God has made me laugh, and everyone who hears will laugh with me.”
7 She also said, “Who would have told Abraham that Sarah would nurse children? Yet I have borne a son for him in his old age.”
