1 Reis 19:17

Him that escapeth the sword of Hazael. — The vengeance wrought by Hazael and Jehu on the faithlessness of Israel speaks for itself; it is marked in bloody letters on the history (2 Reis 10). But Elisha’s mission was obviously not one of such vengeance. He had to destroy enmity, but not to slay the enemies of God. The difficulty, such as it is, is one of the many marks of historic accuracy in the whole passage. Probably Elisha’s mission is here described in the terms in which Elijah would best understand it. His spirit was for war; he could hardly have conceived how the completion of his mission was to be wrought out by the weapons of peace in the hand of his successor. (Comp. 2 Coríntios 10:3.)
