Thus saith the Lord GOD; I will also take of the highest branch {n} of the high cedar, and will set it; I will crop off from the {o} top of its young twigs a tender one, and will plant it upon an high mountain and eminent:

(n) This promise is made to the Church which will be as a small remnant, and as the top of a tree.

(o) I will trim it, and dress it.

Wesley's Notes

17:22 The highest branch - Of the royal seed; of the highest branch that is heir to the throne; namely, the Messiah. An high mountain - Upon mount Zion. Eminent - Not for outward splendor, but for spiritual advantages.

Jamieson-Fausset-Brown Bible Commentary

22. When the state of Israel shall seem past recovery, Messiah, Jehovah Himself, will unexpectedly appear on the scene as Redeemer of His people (Isa 63:5).

I . also-God opposes Himself to Nebuchadnezzar: "He took of the seed of the land and planted it (Eze 17:3, 5), so will I, but with better success than he had. The branch he plucked (Zedekiah) and planted, flourished but for a time, to perish at last; I will plant a scion of the same tree, the house of David, to whom the kingdom belongs by an everlasting covenant, and it shall be the shelter of the whole world, and shall be for ever."

branch-the peculiar title of Messiah (Zec 3:8; 6:12; Isa 11:1; 4:2; Jer 23:5; 33:15).

a tender one-Zerubbabel never reigned as a universal (Eze 17:23) king, nor could the great things mentioned here be said of him, except as a type of Messiah. Messiah alone can be meant: originally "a tender plant and root out of a dry ground" (Isa 53:2); the beginning of His kingdom being humble, His reputed parents of lowly rank, though King David's lineal representatives; yet, even then, God here calls Him, in respect to His everlasting purpose, "the highest . of the high" (Ps 89:27).

I . will plant it upon an high mountain-Zion; destined to be the moral center and eminence of grace and glory shining forth to the world, out-topping all mundane elevation. The kingdom, typically begun at the return from Babylon, and the rebuilding of the temple, fully began with Christ's appearing, and shall have its highest manifestation at His reappearing to reign on Zion, and thence over the whole earth (Ps 2:6, 8; Isa 2:2, 3; Jer 3:17).

Matthew Henry's Concise Commentary

17:22-24 The unbelief of man shall not make the promise of God of none effect. The parable of a tree, used in the threatening, is here presented in the promise. It appears only applicable to Jesus, the Son of David, the Messiah of God. The kingdom of Satan, which has borne so long, so large a sway, shall be broken, and the kingdom of Christ, which was looked upon with contempt, shall be established. Blessed be God, our Redeemer is seen even by the ends of the earth. We may find refuge from the wrath to come, and from every enemy and danger, under his shadow; and believers are fruitful in him.
