1 Kings 19:1-3

American Standard Version

19 And Ahab told Jezebel all that Elijah had done, and withal how he had slain all the prophets with the sword. ² Then Jezebel sent a messenger unto Elijah, saying, So let the gods do to me, and more also, if I make not thy life as the life of one of them by to-morrow about this time. ³ And when he saw that, he arose, and went for his life, and came to Beer-sheba, which belongeth to Judah, and left his servant there.
