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").
