1 Kings 19:5-8

5 He lay down and slept under a juniper tree; and, behold, an angel touched him, and said to him, Arise and eat.  6 He looked, and, behold, there was at his head a cake baked on the coals, and a jar of water. He ate and drink, and laid him down again.  7 The angel of Yahweh came again the second time, and touched him, and said, Arise and eat, because the journey is too great for you.  8 He arose, and ate and drink, and went in the strength of that food forty days and forty nights to Horeb the Mount of God.
