four chariots
The interpretation of the tenth vision must be governed by the authoritative declaration of (Zac 6:5). That which is symbolized by the four chariots with their horses is not the four world-empires of Daniel, but "the four spirits of heaven which go forth from standing before the Lord of all the earth" (Zac 6:5).
These "spirits" are angels; (Luk 1:19); (Heb 1:14) and are most naturally interpreted of the four angels of; (Rev 7:1-3); (Rev 9:14); (Rev 9:15). These have also a ministry earthward, and of like nature with the "spirits" of (Zac 6:1-8). namely, judgment.
The symbol (chariots and horses) is in perfect harmony with this. Always in Scripture symbolism they stand for the power of God earthward in judgment. (Jer 46:9); (Jer 46:10); (Joe 2:3-11); (Nah 3:1-7).
The vision, then, speaks of the Lord's judgments upon the Gentile nations north and south in the day of the Lord; (Isa 2:10-22); (Rev 19:11-21).

crowns
Following the earth-judgments symbolized in the horsed chariots (Zac 6:1-8) comes the manifestation of Christ in His kingdom glory (Zac 6:9-15).
This is the invariable prophetic order: first the judgments of the day of the Lord; (Isa 2:10-22); (Rev 19:11-21) then the kingdom (cf); (Psa 2:5); (Psa 2:6); (Isa 3:24-26); (Isa 4:2-6); (Isa 10:33); (Isa 10:34); (Isa 11:1-10); (Rev 19:19-21); (Rev 20:4-6). This is set forth symbolically by the crowning of Joshua, which was not a vision, but actually done
Compare (Isa 8:3); (Isa 8:4); (Eze 37:16-22).
The fulfilment in the BRANCH will infinitely transcend the symbol. He "shall bear the glory"; (Zac 6:13); (Mat 16:27); (Mat 24:30); (Mat 25:31) as the Priest-King on His own throne (Zac 6:12); (Zac 6:13); (Heb 7:1-3).
Christ is now a Priest, but still in the holiest within the veil; (Lev 16:15); (Heb 9:11-14); (Heb 9:24) and seated on the Father's throne (Rev 3:21). He has not yet come out to take His own throne (Heb 9:28). The crowns made for the symbolical crowning of Joshua were to be laid up in the temple as a memorial to keep alive this larger hope of Israel.
