Genesis 21:9-11

Authorized (King James) Version

⁹ And Sarah saw the son of Hagar the Egyptian, which she had born unto Abraham, mocking. ¹⁰ Wherefore 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.
