1 The Lord came back to visit Sarah as he said he would, and he kept his promise to her.
2 At exactly the time God said it would happen, Sarah became pregnant and gave birth to a son for Abraham in his old age.
3 Abraham named his son Isaac.
4 Abraham did what God commanded and circumcised Isaac when he was eight days old.
5 Abraham was 100 years old when his son Isaac was born.
6 Sarah said, “God has made me happy, and everyone who hears about this will be happy with me.
7 No one thought that I, Sarah, would be able to have Abraham’s child. But I have given Abraham a son, even though he is old.”
