1 Kings 19:7-9 ESV
And the angel of the LORD came again a second time and touched him and said, “Arise and eat, for the journey is too great for you.” 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.
There he came to a cave and lodged in it. And behold, the word of the LORD came to him, and he said to him, “What are you doing here, Elijah?”
