Sacharja 6:4

The two kingdoms of providence and grace are what we are all very nearly interested in, and therefore are concerned to acquaint ourselves with, all our temporal affairs being in a necessary subjection to divine Providence, and all our spiritual and eternal concerns in a necessary dependence upon divine grace; and these two are represented to us in this chapter - the former by a vision, the latter by a type. Here is, I. God, as King of nations, ruling the world by the ministry of angels, in the vision of the four chariots (Zac 6:1-8). II. God, as King of saints, ruling the church by the mediation of Christ, in the figure of Joshua the high priest crowned, the ceremony performed, and then explained concerning Christ (Zac 6:9-15).
