How can it rest when the LORD has commanded it? He has appointed it against Ashkelon and the shore of its coastland.”
Some take it, ה, he, as meaning the land itself; but as it immediately follows, against Ashkelon and against the seashore, it is better to explain it as above. By the sea-shore some understand Joppa; but it is probable that the Prophet includes the whole coast, and that he thus still speaks of Tyre, and Sidon, and Gaza, though he names Ashkelon, which was a little distant from the sea.
As the Egyptians had often proved false friends, so the Philistines had always been sworn enemies, to the Israel of God, and the more dangerous and vexatious for their being such near neighbours to them. They were considerably humbled in David's time, but, it seems they had got head again and were a considerable people till Nebuchadnezzar cut them off with their neighbours, which is the event here foretold.
Commenting on Jeremiah 47:1-7
