John Gill Commentary Ezekiel 26:21

"I will make thee a terror, and thou shalt no more have any being; though thou be sought for, yet shalt thou never be found again, saith the Lord Jehovah." — Ezekiel 26:21 (ASV)

I will make you a terror To all the isles round about, who shall shake and tremble at the ruin of Tyre, as before observed; or to herself, being brought into a most terrible and distressed condition:

and you shall be no more : in the same place and situation, in the same happy state and condition:

though you be sought for, yet shall you never be found again, saith the Lord God :

this is true of the antitype, Babylon, or antichrist, (Revelation 18:21) .
