I will cut off the inhabitant from Ashdod, And him who holds the scepter from Ashkelon; And I will turn my hand against Ekron; And the remnant of the Philistines will perish," says the Lord Yahweh.
Regarding Damascus.  Tiglath-pileser king of Assyria fulfilled this prophecy when Ahaz applied to him for help.  The Assyrian monarch destroyed the royal family, captured Damascus and carried its people captive into Kir.[30]  This fulfillment occurred fifty years after the prophecy of Amos and is recorded in  2 Kings 16:9.[31]
