Genesis 21:17-20; 1 Kings 19:5-7

17 And 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? Fear not, for God has heard the voice of the boy where he is. 18 Up! Lift up the boy, and hold him fast with your hand, for I will make him into a great nation." 19 Then God opened her eyes, and she saw a well of water. And she went and filled the skin with water and gave the boy a drink. 20 And God was with the boy, and he grew up. He lived in the wilderness and became an expert with the bow.
5 And he lay down and slept under a broom tree. And behold, an angel touched him and said to him, "Arise and eat." 6 And he looked, and behold, there was at his head a cake baked on hot stones and a jar of water. And he ate and drank and lay down again. 7 And the angel of the LORD came again a second time and touched him and said, "Arise and eat, for the journey is too great for you."
