1 Kings 19: 4 - 8
4 But he himself went a day's journey into the wilderness, and came and sat down under a broom tree; and he asked that he might die, saying, "It is enough; now, O LORD, take away my life; for I am no better than my fathers."
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, else the journey will be too great for you."
8 And he arose, and ate and drank, and went in the strength of that food forty days and forty nights to Horeb the mount of God.
