Amos 1:8

8“And I will cut off and destroy the inhabitants from Ashdod,

And the ruler who holds the scepter, from Ashkelon;

And I will unleash My power and turn My hand [in judgment] against Ekron,

And the rest of the Philistines [in Gath and the towns dependent on these four Philistine cities] shall die,”

Says the Lord God. [Josh 13:3]
