1 Kings 19:1-3

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