Genesis 21:11-13
Genesis 21:11-13 ASV
And the thing was very grievous in Abraham’s sight on account of his son. 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. And also of the son of the handmaid will I make a nation, because he is thy seed.
