1 Kings 19:5-9

And as he lay and slept under a juniper tree, behold, then an angel touched him, and said unto him, Arise and eat. And he looked, and, behold, there was a cake baken on the coals, and a cruse of water at his head. And he did eat and drink, and laid him down again. And the angel of the LORD 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 meat 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 the LORD came to him, and he said unto him, What doest thou here, Elijah?
