Zechariah 9:6

6. The full-blooded Philistines will be displaced by a mixed race.

A bastard Margin R.V., “a bastard race.” An obscure phrase. In Deuteronomy 23:2, the word denotes one who is not a full-blooded citizen, one with whose birth a blemish of some sort is connected. Here it seems to denote a race which, from the view point of the Philistines, is not full-blooded, a foreign or mixed race. The term implies nothing concerning the moral character of the new population.

Ashdod What is true of one city is true of the whole land.

The pride of the Philistines The judgment implied in 6a will be sufficient to bring to an end the pride and haughtiness of the Philistines; they will be completely humiliated.
