John Trapp on Zephaniah 2:5

Verſe 5. Woe to the Inhabitants of the ſea coaſt] Theſe were the Philiſtines: they lay between the Jewes and the Sea: God having ſo diſpoſed of it, that his people might not have much commerce with forreign nations nor learn their manners. Into havens and maritime towns there is uſually a conflux of vices, like as there is of waters into the Sea: witneſſe Tyre and Sydon, Corinth, Carthage, Capernaum, &c. Hence that proverb maritimi mores: and that cenſure of ſuch people littorales duri, horridi, immanes, latrociniis dedicit omnium denique peſſimi, Thoſe that dwell by the Sea-ſide are uſually ill-conditioned, fierce, cruell, theeviſh, and the worſt of men. Theſe Philiſtines were no better, and are therefore here put under a woe, and threatened with utter deſtruction.

The nation of the Cherethites] i. e. Deſtroyers: ſo the Philiſtines had ſtiled themſelves, as glorying to have conquered and cut off many people. The old Latine tranſlation rendreth it Gens perditorum The nation of Deſtroyers: ſo doth Aquila, Theodotion, and Symmachus, Now it comes to their turn to be deſtroyed, according to Eſay 33.1. That theſe Cherethites were a ſort of Philiſtines See 1 Sam. 30.14, 16. Ezek. 25.16. That they were valiant men appears by that legion of them that guarded David 2 Sam. 9.4. and 15.18. and were highly eſteemed by him, becauſe they ſtuck to him in his affliction at Gath, and alſo when Abſolom was up in arms 2 Sam. 15.18.

the word of the Lord is againſt you] And not onely againſt Iſrael. This was ſpoken, as for the terrour of thoſe Philiſtines, who thought themſelves out of the reach of Gods rod, and ſlighted his word, ſo for the comfort of the people of God, who thought much that themſelves ſhould be ſo ſeverely dealt with, and the uncircumciſed Philiſtines ſcape ſcot-free.

O Canaan the land of the Philiſtines] Indeed of the Iſraelites, Joſh. 13.3. but held by force by the Philiſtienes, who were of the ſtock of the Canaanites, but not ſubdued; and had detained part of the land from the right owners for 800. years and upwards; and now they come to be reckoned with. Subitò tollitur qui diu toleratur.

I will even deſtroy thee, that there ſhall be no inhabitant] No ſetled inhabitant, that ſhall fix there, as the word ſignifieth. Thus Poena venit gravior, quo mage ſera venit, the longer God ſtayes, the heavier he ſtrikes.
