Thematic Bible: Speaking evil of, forbidden

Nevertheless in the same way also these men who dream, indeed defile flesh, and reject lordship, and speak evil of dignities. But Michael the arch-agent, when he disputed with the devil, contending about the body of Moses, dared not bring a railing judgment, but said, May Lord rebuke thee. But these men indeed revile whatever they have not seen. But whatever they understand naturally, as the irrational beasts, in these things they are corrupted.
