Elijah had just had a major victory. He caused 450 prophets of Baal to be killed. When he did this Queen Jezebel wanted to find him. She said she would have him killed.

Elijah was feeling down after all of this. God came to him. He helped him have food to eat. Then He told Elijah to go to to Mount Sinai. There God spoke to him again and gave him a plan of what he should do next.

1 Kings 19:8-18

8 So he got up and ate and drank. Strengthened by that food, he traveled forty days and forty nights until he reached Horeb, the mountain of God. 9 There he went into a cave and spent the night.

The Lord Appears to Elijah
And the word of the Lord came to him: “What are you doing here, Elijah?”

10 He replied, “I have been very zealous for the Lord God Almighty. The Israelites have rejected your covenant, torn down your altars, and put your prophets to death with the sword. I am the only one left, and now they are trying to kill me too.”

11 The Lord said, “Go out and stand on the mountain in the presence of the Lord, for the Lord is about to pass by.”

Then a great and powerful wind tore the mountains apart and shattered the rocks before the Lord, but the Lord was not in the wind. After the wind there was an earthquake, but the Lord was not in the earthquake. 12 After the earthquake came a fire, but the Lord was not in the fire. And after the fire came a gentle whisper. 13 When Elijah heard it, he pulled his cloak over his face and went out and stood at the mouth of the cave.

Then a voice said to him, “What are you doing here, Elijah?”

14 He replied, “I have been very zealous for the Lord God Almighty. The Israelites have rejected your covenant, torn down your altars, and put your prophets to death with the sword. I am the only one left, and now they are trying to kill me too.”

15 The Lord said to him, “Go back the way you came, and go to the Desert of Damascus. When you get there, anoint Hazael king over Aram. 16 Also, anoint Jehu son of Nimshi king over Israel, and anoint Elisha son of Shaphat from Abel Meholah to succeed you as prophet. 17 Jehu will put to death any who escape the sword of Hazael, and Elisha will put to death any who escape the sword of Jehu. 18 Yet I reserve seven thousand in Israel—all whose knees have not bowed down to Baal and whose mouths have not kissed him.”
