2 And Sarah conceived and bore Abraham a son in his old age at the time of which God had spoken to him.
3 Abraham called the name of his son who was born to him, whom Sarah bore him, Isaac.
4 And Abraham circumcised his son Isaac when he was eight days old, as God had commanded him.
5 Abraham was a hundred years old when his son Isaac was born to him.
6 And Sarah said, “God has made laughter for me; everyone who hears will laugh over me.”
7 And she said, “Who would have said to Abraham that Sarah would nurse children? Yet I have borne him a son in his old age.”
8 And the child grew and was weaned. And Abraham made a great feast on the day that Isaac was weaned.
