Isaiah 33:1

Here we have, I. The proud and false Assyrian justly reckoned with for all his fraud and violence, and laid under a woe, Isa 33:1. Observe, 1. The sin which the enemy had been guilty of. He had spoiled the people of God, and made a prey of them, and herein had broken his treaty of peace with them, and dealt treacherously. Truth and mercy are two such sacred things, and have so much of God in them, that those cannot but be under the wrath of God that make conscience of neither, but are perfectly lost to both, that care not what mischief they do, what spoil they make, what dissimulations they are guilty of, nor what solemn engagements they violate, to compass their own wicked designs. Bloody and deceitful men are the worst of men. 2. The aggravation of this sin. He spoiled those that had never done him any injury and that he had no pretence to quarrel with, and dealt treacherously with those that had always dealt faithfully with him. Note, The less provocation we have from men to do a wrong thing the more provocation we give to God by doing it. 3. The punishment he should fall under for this sin. He that spoiled the cities of Judah shall have his own army destroyed by an angel and his camp plundered by those whom he had made a prey of. The Chaldeans shall deal treacherously with the Assyrians and revolt from them.
