Matthew Poole and continuators on Isaiah 23:13

13 Behold the land of the Caldeans; this people was not, till the Assyrian founded it for them that dwell in the wilderness: they set up the towers thereof, they raised up the palaces thereof, and he brought it to ruine.

You Tyrians, who think your City impregnable, cast your Eyes upon the Land and Empire of the Chaldeans, or Babylonians; which, though now it be a flourishing Kingdom, and shall shortly grow far more glorious and potent, even the glory of kingdoms, as it is called Isa. 13. 19. yet shall certainly be brought to utter ruine: and therefore your Presumption is most vain and unreasonable.

The Chaldeans at first were not a People, not formed into any Commonwealth or Kingdom.

Till Nimrod, the Head and Founder of the Assyrian Monarchy, built Babel, Gen. 10, 9. now the Head of the Chaldean Monarchy, which he built for those People, who then lived in Tents, and were dispersed here and there in wild and waste Places, that he might bring them into Order, and under Government, and thereby establish and promote his own Empire.

The Chaldeans being by this means brought together into a Body, fell to the Work of Building their City, and its Towers and Palaces, and thereby got Power and Dominion over their Neighbours, till at last they grew the greatest of all the Monarchies that then were upon Earth.

The Lord, who is expressed before, and is frequently designed in Scripture by this indefinite Pronoun he, as hath been many times observed: Whereby he insinuates the true Reason why neither the Chaldeans nor the Tyrians should be able to stand, because the Almighty God was engaged against them.

Will infallibly bring that great Empire to ruine. He speaks of a future thing as if it were already past, as the Prophets use to do. The Chaldeans shall now return to their first Nothing, and become no People again.
