Gen 21:1-7

The Birth of Isaac 1The Lord dealt with Sarah as he had said, and the Lord did for Sarah as he had promised.2Sarah conceived and bore Abraham a son in his old age, at the time of which God had spoken to him.3Abraham gave the name Isaac to his son whom Sarah bore him.4And Abraham circumcised his son Isaac when he was eight days old, as God had commanded him.5Abraham was a hundred years old when his son Isaac was born to him.6Now Sarah said, “God has brought laughter for me; everyone who hears will laugh with me.”7And she said, “Who would ever have said to Abraham that Sarah would nurse children? Yet I have borne him a son in his old age.”
