Jeremiah 25:20 - Matthew Poole's English Annotations on the Holy Bible

It is of no great moment to determine whether God by the mingled people, here mentioned, intended the various nations afterwards particularly expressed by their names, or some people that were not native Egyptians, but lived mingled with them, or some other people of several nations who lived near Judea or the Arabians. By the kings of the land of Uz, it is most probably judged are to be understood those kings who ruled over that people, who descended from Dishan, Genesis 36:28, and are judged to have inhabited some part of Arabia Petraea, near to Idumea. The cities of the Philistines are reckoned afterward. Azzah, Ekron, Ashdod, and Ashkelon were four of them; the fifth, which was Gath, is not here named. See 1 Samuel 6:17. It had a king in former times, to whom David fled, 1 Samuel 21:10; but before this time it was destroyed, either by Psammeticus, father to Pharaoh-nechoh, or by Tartan, captain-general to Sargon king of Assyria, of whom read Isaiah 20:1, that he took Ashdod, which may be the reason that here mention is made of no more than the remnant of Ashdod.
