Amos 1:6-10

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:

But I will send a fire on the wall of Gaza, which shall devour the palaces thereof:

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.

Thus saith the LORD; For three transgressions of Tyrus, and for four, I will not turn away the punishment thereof; because they delivered up the whole captivity to Edom, and remembered not the brotherly covenant:

But I will send a fire on the wall of Tyrus, which shall devour the palaces thereof.
