2 For Sarah conceived and bore Abraham a son in his old age, at the set time of which God had spoken to him.
3 And Abraham called the name of his son that was born to him, whom Sarah bore to him, Isaac.
4 And Abraham circumcised his son Isaac, being eight days old, as God had commanded him.
5 And Abraham was a hundred years old, when his son Isaac was born to him.
6 And Sarah said, God hath made me to laugh, so that all that hear will laugh with me.
7 And she said, Who would have said to Abraham, that Sarah shall nurse children? for I have borne him a son in his old age.
8 And the child grew, and was weaned: and Abraham made a great feast the day that Isaac was weaned.
