Zechariah 9:5-7

Ashkelon shall see it, and fear; Gaza also shall see it, and be very sorrowful, and Ekron; for her expectation shall be ashamed; and the king shall perish from Gaza, and Ashkelon shall not be inhabited. And a bastard shall dwell in Ashdod, and I will cut off the pride of the Philistines. And I will take away his blood out of his mouth, and his abominations from between his teeth: but he that remaineth, even he, shall be for our God, and he shall be as a governor in Judah, and Ekron as a Jebusite.
