Genesis 21:11-13

American Standard Version

¹¹ And the thing was very grievous in Abraham’s sight on account of his son. ¹² And God said unto Abraham, Let it not be grievous in thy sight because of the lad, and because of thy handmaid; in all that Sarah saith unto thee, hearken unto her voice; for in Isaac shall thy seed be called. ¹³ And also of the son of the handmaid will I make a nation, because he is thy seed.
