Now the LORD was gracious to Sarah1 as he had said, and the LORD did for Sarah what he had promised.22
Sarah became pregnant and bore a son3 to Abraham in his old age,4 at the very time God had promised him.53
Abraham gave the name Isaaca6 to the son Sarah bore him.
When his son Isaac was eight days old, Abraham circumcised him,7 as God commanded him.
Abraham was a hundred years old8 when his son Isaac was born to him.
Sarah said, "God has brought me laughter,9 and everyone who hears about this will laugh with me."
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."10
