Genesis 21:13

11The thing was very grievous in Abraham’s sight on account of his son.

12God 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.

13I will also make a nation of the son of the servant, because he is your child.”

14Abraham 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.

15The water in the container was spent, and she put the child under one of the shrubs.
