1 Then the Lord took note of Sarah as He had said, and the Lord did for Sarah as He had promised.
2 So Sarah conceived and bore a son to Abraham in his old age, at the appointed time of which God had spoken to him.
3 Abraham called the name of his son who was born to him, whom Sarah bore to him, Isaac.
4 Then Abraham circumcised his son Isaac when he was eight days old, as God had commanded him.
5 Now Abraham was one hundred years old when his son Isaac was born to him.
6 Sarah said, "God has made laughter for me; everyone who hears will laugh with me."
