Genesis 21:7-9

Revised Geneva Translation

⁷ Again she said, “Who would have said to Abraham that Sarah would have given children suck? For I have borne him a son in his old age.”

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

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