Zephaniah 2:5 - Matthew Poole's English Annotations on the Holy Bible

Woe unto the inhabitants! now all the Philistines are threatened, whereas before he named only those four cities. Of the sea-coasts; the coasts of the great or western sea, now the Mediterranean, on which the Philistines of old did dwell. The Cherethites, or destroyers, men that were stout, but fierce, and perhaps terrible to neighbours and foreigners that had the hard hap to be forced on their coasts by violence of sea. They were great soldiers, and lived Switzerlike, guards to David, it may be to other kings also. The word of the Lord; his purpose, his threats too by his prophet. Canaan; that part that the Philistines did by three keep from the Jews. I will even destroy thee: though the Chaldeans be the men that shall destroy, yet the Lord will do it also; they his servants, he chief, in doing it. There shall be no inhabitant; no more cities, nor citizens to dwell therein.
