Genesis 21:13

Therefore she said to Abraham, “Cast out this servant and her son! For the son of this servant will not be heir with my son, Isaac.”

The thing was very grievous in Abraham’s sight on account of his son.

God said to Abraham, “Don’t let it be grievous in your sight because of the boy, and because of your servant. In all that Sarah says to you, listen to her voice. For your offspring will be named through Isaac.

Abraham rose up early in the morning, and took bread and a container of water, and gave it to Hagar, putting it on her shoulder; and gave her the child, and sent her away. She departed, and wandered in the wilderness of Beersheba.

The water in the container was spent, and she put the child under one of the shrubs.

She went and sat down opposite him, a good way off, about a bow shot away. For she said, “Don’t let me see the death of the child.” She sat opposite him, and lifted up her voice, and wept.
