:
1 The word of the LORD that came to Jeremiah the prophet against the Philistines, before that Pharaoh smote Gaza. 2 Thus saith the LORD; Behold, waters rise up out of the north, and shall be an overflowing flood, and shall 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. 3 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; 4 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. 5 Baldness is come upon Gaza; Ashkelon is cut off with the remnant of their valley: how long wilt thou cut thyself? 6 O thou sword of the LORD, how long will it be ere thou be quiet? put up thyself into thy scabbard, rest, and be still. 7 How can it be quiet, seeing the LORD hath given it a charge against Ashkelon, and against the sea shore? there hath he appointed it.
[AD 458] Theodoret of Cyrus on Jeremiah 47:1-7
Now he directs his prophecy against foreigners. He calls the inhabitants of Ashkelon, Gaza, Azotus, Gath and Ekron “foreigners.” He says that the prediction took place before Pharaoh struck Gaza, and he likens the army of the Babylonians to a flooding river swollen by rain and melted snow. Cities will be overwhelmed by this flood; their inhabitants will be destroyed and lament and be unable to bear the din of the arms and chariots.

He calls Nebuchadnezzar “the sword of the Lord,” for he does those things by God’s permission, and the impious pay the penalty for their ungodliness at one another’s hands.
