1 Kings 19:1-3, 13-14

Now Ahab told Jezebel all that Elijah had done, and how he had killed all the prophets [of Baal] with the sword. Then Jezebel sent a messenger to Elijah, saying, “So may the gods do to me, and even more, if by this time tomorrow I do not make your life like the life of one of them.” And Elijah was afraid and arose and ran for his life, and he came to Beersheba which belongs to Judah, and he left his servant there.

When Elijah heard the sound, he wrapped his face in his mantle (cloak) and went out and stood in the entrance of the cave. And behold, a voice came to him and said, “What are you doing here, Elijah?” He said, “I have been very zealous for the LORD God of hosts (armies), because the sons of Israel have abandoned (broken) Your covenant, torn down Your altars and killed Your prophets with the sword. And I, only I, am left; and they seek to take away my life.”
