John Gill Commentary Ezekiel 30:12

"And I will make the rivers dry, and will sell the land into the hand of evil men; and I will make the land desolate, and all that is therein, by the hand of strangers: I, Jehovah, have spoken it." — Ezekiel 30:12 (ASV)

And I will make the rivers dry
Egypt was a country that abounded with rivers and canals cut from the river Nile; its wealth and riches very much depended on this, partly on account of the multitude of fishes taken from them, and the paper reeds that grew on their banks; but chiefly because the whole land was watered by them, and made exceedingly fruitful, rain not being so common in it; so that to dry up the rivers was in effect to take away their substance and dependence; besides, this made the way easy and passable for the enemy; there was nothing to obstruct him, he could overrun and ravage the land at pleasure:

and sell the land into the hand of the wicked ;
the Chaldeans under Nebuchadnezzar, who were wicked idolaters, men of wicked lives, and of merciless and cruel dispositions; who would show no favor to the inhabitants of the land when delivered up to them, which is called a selling it; for, as things sold are delivered to the buyer, so this land would be delivered to them; which though they had no right to it before, yet by the event of war and the disposal of divine Providence, came to have a property in it, given them by him who is the proprietor of all lands; and after them into the hands of the Persians, under Cambyses and Ochus; who were very wicked and cruel princes, and may be reckoned among the terrible or violent ones of the nations in the preceding verse; and then into the hands of the Grecians, Romans, Saracens, Mamalucks, and now the Turks, all very wicked people:

and I will make the land waste, and all that is therein, by the hand of
strangers ;
the Babylonians, people of another and distant country, of another language, and with whom they had no commerce, alliance, or friendship, and so would not spare them or their land when in their possession; and so all the rest mentioned above, into whose hands they successively fell:

I the Lord have spoken it ;
determined it, prophesied of it; and it shall come to pass, as it did accordingly.
