Amos 1:7
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 captive 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.
