Genesis 21

The Birth of Isaac

1The Lord kept his word and did for Sarah exactly what he had promised. 2She became pregnant, and she gave birth to a son for Abraham in his old age. This happened at just the time God had said it would. 3And Abraham named their son Isaac. 4Eight days after Isaac was born, Abraham circumcised him as God had commanded. 5Abraham was 100 years old when Isaac was born.

6And Sarah declared, “God has brought me laughter.* All who hear about this will laugh with me. 7Who would have said to Abraham that Sarah would nurse a baby? Yet I have given Abraham a son in his old age!”
