1. The prevalency of sin, that iniquity should abound (v. 16): The treacherous dealers have dealt treacherously; this is itself a judgment, and that which provokes God to bring other judgments. (1.) Men are false to one another; there is no faith in man, but a universal dishonesty. Truth, that sacred bond of society, has departed, and there is nothing but treachery in men's dealings. See Jer. ix. 1, 2. (2.) They are all false to their God; as to him, and their covenant with him, the children of men are all treacherous dealers, and have dealt very treacherously with their God, in departing from their allegiance to him. This is the original, and this the aggravation, of the sin of the world; and, when men have been false to their God, how should they be true to any other?
