3 And Abraham called the name of his son who 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 has made me laugh: all that hear will laugh with me.
7 And she said, Who would have said to Abraham, Sarah will suckle 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 on the day that Isaac was weaned.
9 And Sarah saw the son of Hagar the Egyptian, whom she had borne to Abraham, mocking.
