Albert Barnes Commentary 2 Kings 6:33

"And while he was yet talking with them, behold, the messenger came down unto him: and he said, Behold, this evil is of Jehovah; why should I wait for Jehovah any longer?" — 2 Kings 6:33 (ASV)

The messenger - It has been proposed to change “messenger” to “king,” since the two words are nearly alike in Hebrew, and the speech with which the chapter ends is considered suitable only for the king, whose presence is indicated in 2 Kings 7:2 and 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 the wall to the level of the streets.

Behold this evil ... - Jehoram bursts into the prophet’s presence with a justification for the sentence he has pronounced against him (2 Kings 6:31). “Behold, this evil—this siege with all its horrors—is from Yahweh, from Yahweh, whose prophet you are. Why should I wait for Yahweh—to temporize with Him and keep on terms with Him, as it were, by allowing you to live—any longer? What do you have to say in arrest of judgment?”
