1 The Lord cared for Sarah as he had said and did for her what he had promised.
2 Sarah became pregnant and 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, the son Sarah gave birth to.
4 He circumcised Isaac when he was eight days old as God had commanded.
5 Abraham was one hundred 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 even though Abraham is old I have given him a son.”
