Genesis 21:7 ASV

⁵  And Abraham was a hundred years old, when his son Isaac was born unto him.

⁶  And Sarah said, God hath made me to laugh. Every one that heareth will laugh with me.

⁷  And she said, Who would have said unto Abraham, that Sarah should give children suck? For I have borne him a son in his old age.

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

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