Genesis 21:3-9 Amplified Bible (AMP)

3. Abraham named his son whom Sarah bore to him Isaac [laughter].

4. And Abraham circumcised his son Isaac when he was eight days old, as God had commanded him.

5. Abraham was a hundred years old when Isaac was born.

6. And Sarah said, God has made me to laugh; all who hear will laugh with me.

7. And she said, Who would have said to Abraham that Sarah would nurse children at the breast? For I have borne him a son in his old age! [Heb. 11:12.]

8. And the child grew and was weaned, and Abraham made a great feast the same day that Isaac was weaned.

9. Now Sarah saw the son of Hagar the Egyptian, whom she had borne to Abraham, mocking [Isaac].
