Behold, this evil is of the Lord - It is difficult to know whether it be the prophet, the messenger, or the king, that says these words. It might be the answer of the prophet from within to the messenger who was without, and who sought for admission, and gave his reason; to whom Elisha might have replied: "I am not the cause of these calamities; they are from the Lord; I have been praying for their removal; but why should I pray to the Lord any longer, for the time of your deliverance is at hand?" And then Elisha said, - see the following chapter, 2 Kings 7 (note), where the removal of the calamity is foretold in the most explicit manner; and indeed the chapter is unhappily divided from this. The seventh chapter should have begun with 2 Kings 6:24; of this chapter, as, by the present division, the story is unnaturally interrupted.
How natural is it for men to lay the cause of their suffering on any thing or person but themselves! Ahab's iniquity was sufficient to have brought down God's displeasure on a whole nation; and yet he takes no blame to himself, but lays all on the prophet, who was the only salt that preserved the whole nation from corruption. How few take their sins to themselves! and till they do this, they cannot be true penitents; nor can they expect God's wrath to be averted till they feel themselves the chief of sinners.
The messenger - It has been proposed to change “messenger” into “king,” the two words being in Hebrew nearly alike, and the speech with which the chapter ends being considered only suitable in the mouth of the king, whose presence is indicated in 2 Kings 7:2, 2 Kings 7:17. Others think that the words “and the king after him” have fallen out of the text.
Came down - The messenger came down from off the wall to the level of the streets.
Behold this evil - Jehoram bursts into the prophet‘s presence with a justification of the sentence 2 Kings 6:31 he has pronounced against him. “Behold this evil - this siege with all its horrors - is from Yahweh - from Yahweh, Whose prophet thou art. Why should I wait for Yahweh - temporize with Him - keep as it were, on terms with Him by suffering thee to live - any longer? What hast thou to say in arrest of judgment?”
