Genesis 21:13-17

And of the son of the slave woman I will make a nation also, because he is your descendant.”

So Abraham got up early in the morning and took bread and a skin of water, and gave them to Hagar, putting them on her shoulder, and gave her the boy, and sent her away. And she departed and wandered about in the wilderness of Beersheba.

When the water in the skin was used up, she left the boy under one of the bushes.

Then she went and sat down opposite him, about a bowshot away, for she said, “May I not see the boy die!” And she sat opposite him, and raised her voice and wept.

God heard the boy crying; and the angel of God called to Hagar from heaven and said to her, “What is the matter with you, Hagar? Do not fear, for God has heard the voice of the boy where he is.
