Charles Ellicott Commentary Ezekiel 21:27

"I will overturn, overturn, overturn it: this also shall be no more, until he come whose right it is; and I will give it [him]." — Ezekiel 21:27 (ASV)

And it shall be no more. —Literally, this also shall not be. After the emphatic repetition of “over-turn” at the beginning of the verse, it is now added that the condition which follows the overthrow shall not be permanent; ‘the foundations’ shall be put ‘out of course,’ and everything thrown into that condition of flux and change, without permanent settlement, which was so characteristic of the state of Judaea until the coming of Christ.

Until he come whose right it is.— This is generally acknowledged as a reference to Genesis 49:10, “until Shiloh come” even by those who reject the interpretation of Shiloh as meaning “he to whom it belongs.” The promise here made refers plainly both to the priestly and to the royal prerogatives, and a still more distinct foretelling of the union of both in the Messiah may be found in Zechariah 6:12-13. In Him, and in Him alone, will all this confusion and uncertainty come to an end; for, as Ezekiel’s contemporary declared, “His dominion is an everlasting dominion, which shall not pass away, and His kingdom that which shall not be destroyed” (Daniel 7:14).
