Genesis 21:9-16

9And Sarah saw the son of Hagar the Egyptian, whom she had borne unto Abraham, mocking. 10Wherefore she said unto Abraham, Cast out this handmaid and her son: for the son of this handmaid shall not be heir with my son, even with Isaac. 11And the thing was very grievous in Abraham’s sight on account of his son. 12And 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. 13And also of the son of the handmaid will I make a nation, because he is thy seed. 14And Abraham rose up early in the morning, and took bread and a bottle of water, and gave it unto Hagar, putting it on her shoulder, and gave her the child, and sent her away: and she departed, and wandered in the wilderness of Beer-sheba. 15And the water in the bottle was spent, and she cast the child under one of the shrubs. 16And she went, and sat her down over against him a good way off, as it were a bowshot: for she said, Let me not look upon the death of the child. And she sat over against him, and lifted up her voice, and wept.
