I will overturn, overturn, overturn, it: and it shall be no more, until he {y} cometh whose right it is; and I will give it him.

(y) That is, to the coming of Messiah: for though the Jews had some sign of government later under the Persians, Greeks and Romans, yet this restitution was not till Christ's coming and at length would be accomplished as was promised, Ge 49:10.

Wesley's Notes

21:27 Shall be no more - Never recover its former glory, 'till the scepter be quite taken away from Judah, and way be made for the Messiah. He hath an incontestable right to the dominion both in the church and in the world. And in due time he shall have the possession of it, all adverse power being overturned.

King James Translators' Notes

I will overturn...: Heb. Perverted, perverted, perverted, will I make it

Jamieson-Fausset-Brown Bible Commentary

27. Literally, "An overturning, overturning, overturning, will I make it." The threefold repetition denotes the awful certainty of the event; not as Rosenmuller explains, the overthrow of the three, Jehoiakim, Jeconiah, and Zedekiah; for Zedekiah alone is referred to.

it shall be no more, until he come whose right it is-strikingly parallel to Ge 49:10. Nowhere shall there be rest or permanence; all things shall be in fluctuation until He comes who, as the rightful Heir, shall restore the throne of David that fell with Zedekiah. The Hebrew for "right" is "judgment"; it perhaps includes, besides the right to rule, the idea of His rule being one in righteousness (Ps 72:2; Isa 9:6, 7; 11:4; Re 19:11). Others (Nebuchadnezzar, &c.), who held the rule of the earth delegated to them by God, abused it by unrighteousness, and so forfeited the "right." He both has the truest "right" to the rule, and exercises it in "right." It is true the tribal "scepter" continued with Judah "till Shiloh came" (Ge 49:10); but there was no kingly scepter till Messiah came, as the spiritual King then (Joh 18:36, 37); this spiritual kingdom being about to pass into the literal, personal kingdom over Israel at His second coming, when, and not before, this prophecy shall have its exhaustive fulfilment (Lu 1:32, 33; Jer 3:17; 10:7; "To thee doth it appertain").

Matthew Henry's Concise Commentary

21:18-27 By the Spirit of prophecy Ezekiel foresaw Nebuchadnezzar's march from Babylon, which he would determine by divination. The Lord would overturn the government of Judah, till the coming of Him whose right it is. This seems to foretell the overturnings of the Jewish nation to the present day, and the troubles of states and kingdoms, which shall make way for establishing the Messiah's kingdom throughout the earth. The Lord secretly leads all to adopt his wise designs. And in the midst of the most tremendous warnings of wrath, we still hear of mercy, and some mention of Him through whom mercy is shown to sinful men.
