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