The vile person will speak villany. — Another echo, like that of Isaiah 28:23-29, of the teaching of the Book of Proverbs. In that better day men would learn to see men as they are, and not as they pretend to be. “By their fruits ye shall know them” was to be one of the blessings of the reign of the true king (Matthew 7:20).
To utter error against the Lord. — The “error” is either that of “heresy,” or of hollow profession, or of open scoffing. In either case it finds its practical outcome, like the hypocrisy of the Pharisees (Matthew 23:14), in violence and wrong towards the poor and weak.
