1 Kings 19:2 (KJV)

And Ahab told Jezebel all that Elijah had done, and withal how he had slain all the prophets with the sword.

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.

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.

But he himself went a day’s journey into the wilderness, and came and sat down under a juniper tree: and he requested for himself that he might die; and said, It is enough; now, O Lord, take away my life; for I am not better than my fathers.
