I Kings 19:4-8
19:4 But he himself went a day's journey into the wilderness, and came and sat down under a solitary broom tree. He asked that he might die: "It is enough; now, O LORD, take away my life, for I am no better than my ancestors."

19:5 Then he lay down under the broom tree and fell asleep. Suddenly an angel touched him and said to him, "Get up and eat."

19:6 He looked, and there at his head was a cake baked on hot stones, and a jar of water. He ate and drank, and lay down again.

19:7 The angel of the LORD came a second time, touched him, and said, "Get up and eat, otherwise the journey will be too much for you."

19:8 He got up, and ate and drank; then he went in the strength of that food forty days and forty nights to Horeb the mount of God.
