Amos 1:6-8

6 These are the words of the Lord: For three crimes of Gaza, and for four, I will not let its fate be changed; because they took all the people away prisoners, to give them up to Edom.

7 And I will send a fire on the wall of Gaza, burning up its great houses:

8 Him who is seated in power I will have cut off from Ashdod, and him in whose hand is the rod from Ashkelon; and my hand will be turned against Ekron, and the rest of the Philistines will come to destruction, says the Lord God.
