1 Kings 19:15-17

15And Jehovah said to him, Go, return on thy way to the wilderness of Damascus; and when thou comest, anoint Hazael king over Syria;

16and Jehu the son of Nimshi shalt thou anoint king over Israel; and Elisha the son of Shaphat of Abel-meholah shalt thou anoint prophet in thy stead.

17And it shall come to pass, [that] him that escapeth the sword of Hazael shall Jehu slay; and him that escapeth the sword of Jehu shall Elisha slay.
