Genesis 21:17-19

God heard the voice of the boy, and the angel of God called to Hagar from heaven and said to her, “What troubles you, Hagar? Do not be afraid, for God has heard the voice of the boy from where he is [resting]. Get up, help the boy up, and hold him by the hand, for I will make him a great nation.” Then God opened her eyes and she saw a well of water; and she went and filled the [empty] skin with water and gave the boy a drink.
