Adam Clarke on Ezekiel 21:27

I will overturn - I will utterly destroy the Jewish government. Perverted will I make it. Heb. perverted, perverted, perverted I will make it.

Until he come whose - is - משפט mishpat, the judgment; i.e., till the coming of the son of David, the Lord Jesus; who, in a mystic and spiritual sense, shall have the throne of Israel, and whose right it is. See the famous prophecy, Gen 49:10, and Luk 1:32. The עוה avah, which we translate overturn, is thrice repeated here; to point out, say the rabbins, the three conquests of Jerusalem, in which Jehoiakim, Jeconiah, and Zedekiah were overthrown.
