The Birth of Isaac

1 Now the LORD was gracious 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 very time God had promised him.
3 Abraham gave the name Isaaca to the son Sarah bore him.
4 When his son Isaac was eight days old, Abraham circumcised him, as God commanded him.
5 Abraham was a hundred years old when his son Isaac was born to him.
6 Sarah said, “God has brought me laughter, and everyone who hears about this will laugh with me.”
7 And she added, “Who would have said to Abraham that Sarah would nurse children? Yet I have borne him a son in his old age.”
