1 Kings 19:5-9

And he lay down and slept under a juniper-tree; and, behold, an angel touched him, and said unto him, Arise and eat. And he looked, and, behold, there was at his head a cake baken on the coals, and a cruse of water. And he did eat and drink, and laid him down again. And the angel of Jehovah came again the second time, and touched him, and said, Arise and eat, because the journey is too great for thee. And he arose, and did eat and drink, and went in the strength of that food forty days and forty nights unto Horeb the mount of God. And he came thither unto a cave, and lodged there; and, behold, the word of Jehovah came to him, and he said unto him, What doest thou here, Elijah?
