Deuteronomy 17:13

13.And all the people. He shews from the object of the enactment why the proud despisers (of the priests) were not to be spared; for punishments have reference to common example, whilst, on the other hand, impunity is a bait to sin, and the nurse of unbridled licentiousness. And, assuredly, when He commands that the whole people should be inspired with terror, it is a hint that, unless presumption should be corrected, and the bold and wicked should be restrained by severe discipline, the door would be opened to them to destroy the Church.
