Genesis 21:1-5

New Living Translation

The Birth of Isaac

21 The Lord kept his word and did for Sarah exactly what he had promised. ² She 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. ³ And Abraham named their son Isaac. ⁴ Eight days after Isaac was born, Abraham circumcised him as God had commanded. ⁵ Abraham was 100 years old when Isaac was born.
