Jeremiah 47:1-7

In chapter 47 he takes now his prophecies against the Philistines. And the city of Gaza was already taken by the Pharaoh.

The word of the LORD that came to Jeremiah the prophet against the Philistines before that Pharaoh smote Gaza (Jeremiah 47:1).

Now, Pharaoh ultimately smote Gaza, one of the large Philistine cities.

Thus saith the LORD; Behold, waters rise up out of the north, and shall be an overflowing flood (Jeremiah 47:2),

So the waters out of the north would be Babylon.

and they shall overflow the land (Jeremiah 47:2),

The overflowing flood is a type. The word flood is used in typology as the armies. They will overflow the land.

and all that is therein; the city, and them that dwell therein: then the men shall cry, and all the inhabitants of the land shall howl. At the noise of the stamping of the hoofs of his strong horses, at the rushing of his chariots, and at the rumbling of his wheels, the fathers shall not look back to their children for feebleness of hands; Because of the day that cometh to spoil all the Philistines, and to cut off from Tyrus and Zidon every helper that remaineth: for the LORD will spoil the Philistines, the remnant of the country of Caphtor (Jeremiah 47:2-4).

Caphtor is the island of Cyprus from which, or is it Crete where the Philistines originally came from.

Baldness is come upon Gaza; Ashkelon [another Philistine city] is cut off with the remnant of their valley: how long wilt thou cut thyself? O thou sword of the LORD, how long will it be ere you be quiet? put up thyself into thy scabbard, rest, and be still. How can it be quiet, seeing the LORD hath given it a charge against Ashkelon, and against the seashore? there hath he appointed it (Jeremiah 47:5-7).

And so the destruction that was to come upon the Philistines. And, of course, the Philistines were utterly destroyed. The modern Palestinian is not at all related to the Philistines. But the word Palestine does come from this word Philistine.
