1 Kings 19:4-9

But he himself traveled a day’s journey into the wilderness, and he came and sat down under a juniper tree and asked [God] that he might die. He said, “It is enough; now, O LORD, take my life, for I am no better than my fathers.” He lay down and slept under the juniper tree, and behold, an angel touched him and said to him, “Get up and eat.” He looked, and by his head there was a bread cake baked on hot coal, and a pitcher of water. So he ate and drank and lay down again. Then the angel of the LORD came again a second time and touched him and said, “Get up, and eat, for the journey is too long for you [without adequate sustenance].” So he got up and ate and drank, and with the strength of that food he traveled forty days and nights to Horeb (Sinai), the mountain of God. There he came to a cave and spent the night in it; and behold, the word of the LORD came to him, and He said to him, “What are you doing here, Elijah?”
