Thematic Bible: Speaking evil of, forbidden

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