Genesis 21:9-11

21st Century King James Version

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

¹⁰ Therefore she said unto Abraham, “Cast out this bondwoman and her son; for the son of this bondwoman shall not be heir with my son, even with Isaac.”

¹¹ And the thing was very grievous in Abraham’s sight because of his son.
