Zechariah 6

In the final vision of the series of eight visions, Zechariah saw 4 chariots with red, black, white, and dappled horses.  Unlike the first vision, where the spirits or angels were for going to and fro to report back; these were more like those in Revelation 6, carrying out judgments.   The Spirit is at rest when wickedness has been judged.

The message of a crown for Joshua serves almost as a summary conclusion for the visions.   It points to the glorious hope when the Messiah, the Branch, is crowned as Priest-King.

There are many threads woven through all the visions; and essentially they show that wickedness will be judged and destroyed, the Holy City will be cleansed and restored, and the Messiah will reign as Priest and King.

The encouragement for the Israelites is to remind them that the temple they are building is a representation of the future temple from which the Messiah will reign.   That glorious hope is the same one that we as God's People have today, as mentioned in the passage "Those who are far away will come and help to build the temple of the Lord" (vs 6:15a)
