2 Kings 6:33

while he yet talked with them He had hardly explained his knowledge and his wish before action became necessary. The messenger arrived, and we must understand that the king also arrived immediately afterwards, and so the execution of Elisha was stayed, and Jehoram was shewn to be in some degree penitent for his hasty threat.

and he said The words which follow must be the words of the king. He has reached Elisha's house and countermanded his first order. Now his thought is of what shall be done next. The people are at the direst extremity, and God, who has allowed this evil to come upon the nation, gives His prophet no message of relief. In this conviction he is of the mind that Samaria shall be surrendered. Hence his language, -This evil is of the Lord" and He allows it to continue, -why should I wait for the Lord any longer?"
