Genesis 21:1-7

International Standard Version

Isaac is Born

21 The Lord came to Sarah, just as he had said, and the Lord did for Sarah what he had promised. ² Sarah conceived and gave birth to a son for Abraham in his old age, at the very time that God had told him.

³ Abraham named his son who was born to him Isaac—the very one whom Sarah bore for him! ⁴ On the eighth day after his son Isaac had been born,^[a] Abraham circumcised him, just as God had commanded him. ⁵ Abraham was 100 years old when his son Isaac was born to him.

⁶ Now Sarah had said, “God has caused me to laugh,^[b] and all who hear about it^[c] will laugh with me.” ⁷ She also said, “Who would have told Abraham that Sarah would nurse sons? Yet I have given birth to a son in my husband’s^[d] old age!”
