"The priests," says Calmet, "ate the tithes, the first-fruits, and the offerings of the people; the princes received the tributes and imposts and instead of instructing and protecting them, the latter took away their lives by the cruelties they practiced against them: the former destroyed their souls by the poison of their doctrine, and by their bad example. The fat sheep point out the rich to whom these pastors often disguised the truth, by a cruel condescension and complaisance."
