1 Kings 19:12-18

and after the earthquake a fire; but the LORD was not in the fire: and after the fire a still small voice. And it was so, when Elijah heard it, that he wrapped his face in his mantle, and went out, and stood in the entering in of the cave. And, behold, there came a voice unto him, and said, What doest thou here, Elijah? And he said, I have been very jealous for the LORD God of hosts: because the children of Israel have forsaken thy covenant, thrown down thine altars, and slain thy prophets with the sword; and I, even I only, am left; and they seek my life, to take it away. And the LORD said unto him, Go, return on thy way to the wilderness of Damascus: and when thou comest, anoint Hazael to be king over Syria: and Jehu the son of Nimshi shalt thou anoint to be king over Israel: and Elisha the son of Shaphat of Abel-meholah shalt thou anoint to be prophet in thy room. And it shall come to pass, that him that escapeth the sword of Hazael shall Jehu slay: and him that escapeth from the sword of Jehu shall Elisha slay. Yet I have left me seven thousand in Israel, all the knees which have not bowed unto Baal, and every mouth which hath not kissed him.
