For we know him that hath said, Vengeance belongeth unto me, I will recompense, saith the Lord. And again, The Lord shall judge his people.
Him - who utters no empty threats.
Vengeance belongeth unto me - `To me belongeth vengeance:' exactly according with Paul's quotation, Romans 12:19.
Lord shall judge his people - in grace, or else anger, as each deserves: here, "judge" so as to punish the reprobate; there (Deuteronomy 32:35-36), "judge" so as to interpose in behalf of His people.
