Job 34:18 - Albert Barnes' Notes on the Bible

Is it fit to say to a king, Thou art wicked? - The argument here is this: “There would be gross impropriety in arraigning the conduct of an earthly monarch, and using language severely condemning what he does. Respect is due to those of elevated rank. Their plans are often concealed. It is difficult to judge of them until they are fully developed. To condemn those plans, and to use the language of complaint, would not be tolerated, and would be grossly improper. How much more so when that language relates to the Great, the Infinite God, and to his eternal plans!” It may be added here, in accordance with the sentiment of Elihu, that people often indulge in thoughts and language about God which they would not tolerate respecting an earthly monarch.
