John Gill Commentary Ezekiel 23:30

"These things shall be done unto thee, for that thou hast played the harlot after the nations, and because thou art polluted with their idols." — Ezekiel 23:30 (ASV)

And I will do these things unto you
What the Chaldeans did God is said to do, because he suffered them to do these things, as a punishment for their sins; yea, it was according to his will, and by his orders. The Septuagint and Vulgate Latin versions render it, "they have done these things unto you"; that is, the Chaldeans. The Targum is, "your sins are the cause of these things unto you;" that is, their idolatry and other iniquities. Hence the Syriac version is very particular, "for your whoredoms these things shall be done unto you;" and the Arabic version, "your whoredom has done (or is the cause of) these things unto you," as follows:

because you have gone a whoring after the Heathen, and because you
are polluted with their idols ;
imitated them in their idolatries; worshipped the same dunghill gods as they did, as the word signifies; with which it was no wonder they should be polluted, and become abominable unto God.
