“But Elijah himself went a day’s journey into the wilderness. He came and sat down under a solitary broom tree. He asked that he might die. ‘It is enough. Now, O Yahweh, take away my life. I am no better than my ancestors.’ Then he lay down under the broom tree and fell asleep. Suddenly an angel touched him and said to him. ‘Go up and eat.’ He looked. There at his head was a cake baked on hot stones with a jar of water. He ate and drank. Then he lay down again. The angel of Yahweh came again a second time. He touched him and said. ‘Get up and eat, otherwise the journey will be too much for you.’ He got up. He ate and drank. Then he went with the strength of that food forty days and forty nights to Horeb the mount of God.”
Elijah went a day into the wilderness by himself. He almost seemed to despair since he asked that he might die. Then he fell asleep under a broom tree. An angel of Yahweh, not Yahweh himself, told him to get up and eat, twice. This angel of Yahweh came to tell him of his mission. He had to eat and drink to sustain him on his journey. Thus Elijah got up twice and ate and drunk. He will become like the new Moses. He went to Horeb, which is another name for Sinai. He will do the reverse of Moses and go to Horeb from Judah. Instead of taking 40 years, it will only take him 40 days and 40 nights. Still the parallel of 40 sets him up as special like Moses.
