1 Kings 19:5-9

Then he lay down under the tree and slept. Suddenly an angel came to him and touched him. “Get up and eat,” the angel said. Elijah saw near his head a loaf baked over coals and a jar of water, so he ate and drank. Then he went back to sleep. Later the LORD’s angel came to him a second time. The angel touched him and said, “Get up and eat. If you don’t, the journey will be too hard for you.” So Elijah got up and ate and drank. The food made him strong enough to walk for forty days and nights to Mount Sinai, the mountain of God. There Elijah went into a cave and stayed all night. Then the LORD spoke his word to him: “Elijah! Why are you here?”
