I Kings 19:5-8

Then as he lay and slept under a broom tree, suddenly an angel touched him, and said to him, “Arise and eat.” Then he looked, and there by his head was a cake baked on coals, and a jar of water. So he ate and drank, and lay down again. And the angel of the LORD came back the second time, and touched him, and said, “Arise and eat, because the journey is too great for you.” So he arose, and ate and drank; and he went in the strength of that food forty days and forty nights as far as Horeb, the mountain of God.
