Zephaniah 2:4-5

No one will be left in the city of Gaza, and the city of Ashkelon will be destroyed. Ashdod will be empty by noon, and the people of Ekron will be chased away. How terrible it will be for you who live by the Mediterranean Sea, you Philistines! The word of the LORD is against you, Canaan, land of the Philistines. “I will destroy you so that no one will be left.”
