1 The Lord cared for Sarah as he had said. He did for her what he had promised.
2 Sarah became pregnant. And she gave birth to a son for Abraham in his old age. Everything happened at the time God had said it would.
3 Abraham named his son Isaac. Sarah gave birth to this son of Abraham.
4 Abraham circumcised Isaac when he was eight days old as God had commanded.
5 Abraham was 100 years old when his son Isaac was born.
6 And Sarah said, “God has made me laugh. Everyone who hears about this will laugh with me.
7 No one thought that I would be able to have Abraham’s child. But I have given Abraham a son while he is old.”
