Thematic Bible: Speaking evil of, forbidden

In the same manner these deceived dreamers, defile their flesh, despise dominion, and speak evil of higher powers. Yet when Michael, the archangel, contended with the devil, disputing over the body of Moses, he dared not bring against him a curse of judgment, but said, The Lord reprehend thee. But these speak evil of those things which they do not know; but what they know by nature as animals without reason, in those things they corrupt themselves.
