Genesis 21:10-12

Darby Translation

¹⁰ And she said to Abraham, Cast out this handmaid and her son; for the son of this handmaid shall not inherit with my son—with Isaac.

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

¹² And God said to Abraham, Let it not be grievous in thy sight because of the lad and because of thy handmaid: [in] all that Sarah hath said to thee hearken to her voice, for in Isaac shall a seed be called to thee.
