Similar punishments are here held forth to Gaza, Ashdod, Ashkelon, and Ekron, the chief cities of the Philistines, those bitter fees of the Church. They all are brought in for their punishment, who had been so forward in their cruelties to God's people Israel.

Amos 1:6-8
6 Thus saith the LORD; For three transgressions of Gaza, and for four, I will not turn away the punishment thereof; because they carried away captiveb the whole captivity, to deliver them up to Edom:
7 But I will send a fire on the wall of Gaza, which shall devour the palaces thereof:
8 And I will cut off the inhabitant from Ashdod, and him that holdeth the sceptre from Ashkelon, and I will turn mine hand against Ekron: and the remnant of the Philistines shall perish, saith the Lord GOD.
