The angel of God

God heard the voice of the boy. The angel of God called to Hagar out of the sky, and said to her, “What troubles you, Hagar? Don’t be afraid. For God has heard the voice of the boy where he is. Get up, lift up the boy, and hold him with your hand. For I will make him a great nation.” God opened her eyes, and she saw a well of water. She went, filled the container with water, and gave the boy a drink.

Genesis 21:17-19

The angel of God calls to Hagar from the sky, tells her not to be afraid, and points her to a well of water for her son.
