Thematic Bible: Speaking evil of, forbidden

Yet in the same way these men, also by dreaming, defile the flesh, and reject authority, and revile angelic majesties. But Michael the archangel, when he disputed with the devil and argued about the body of Moses, did not dare pronounce against him a railing judgment, but said, "The Lord rebuke you!" But these men revile the things which they do not understand; and the things which they know by instinct, like unreasoning animals, by these things they are destroyed.
