Zechariah 9:5-7

5Ashkelon will see it and be afraid; Gaza too, and will writhe in great pain, as will Ekron, for her hope will fail. There will cease to be a king in Gaza, and Ashkelon will become uninhabited.

6A mongrel people will live in Ashdod, and I will destroy the pride of the Philistines.

7I will remove the blood from their mouths and the abhorrent things from between their teeth. Then they too will become a remnant for our God; they will become like a clan in Judah and Ekron like the Jebusites.
