I. That national sins bring national judgments. When virtue is ruined and laid waste every thing else will soon be ruined and laid waste too (v. 13): When the land sins against me, when vice and wickedness become epidemical, when the land sins by trespassing grievously, when the sinners have become very numerous and their sins very heinous, when gross impieties and immoralities universally prevail, then will I stretch forth my hand upon it, for the punishment of it. The divine power shall be vigorously and openly exerted; the judgments shall be extended and stretched forth to all the corners of the land, to all the concerns and interests of the nation. Grievous sins bring grievous plagues.
