Genesis 21:8-10

Young's Literal Translation

⁸ And the lad groweth, and is weaned, and Abraham maketh a great banquet in the day of Isaac's being weaned;

⁹ and Sarah seeth the son of Hagar the Egyptian, whom she hath borne to Abraham, mocking,

¹⁰ and she saith to Abraham, `Cast out this handmaid and her son; for the son of this handmaid hath no possession with my son -- with Isaac.'
