Genesis 21:5-9 New American Standard Bible (NASB)

5. Now Abraham was one hundred years old when his son Isaac was born to him.

6. Sarah said, "God has made laughter for me; everyone who hears will laugh with me."

7. And she said, "Who would have said to Abraham that Sarah would nurse children? Yet I have borne him a son in his old age."

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

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