2 The Lord will extend your mighty scepter from Zion, saying, "Rule in the midst of your enemies!"
13 It is he who will build the temple of the Lord, and he will be clothed with majesty and will sit and rule on his throne. And he will be a priest on his throne. And there will be harmony between the two.'
(Read Zechariah 6:9-15)
Some Jews from Babylon brought an offering to the house of God. Those who cannot forward a good work by their persons, must, as they are able, forward it by their purses: if some find hands, let others fill them. Crowns are to be made, and put upon the head of Joshua. The sign was used, to make the promise more noticed, that God will, in the fulness of time, raise up a great High Priest, like Joshua, who is but the figure of one that is to come. Christ is not only the Foundation, but the Founder of this temple, by his Spirit and grace. Glory is a burden, but not too heavy for Him to bear who upholds all things. The cross was His glory, and he bore that; so is the crown an exceeding weight of glory, and he bears that. The counsel of peace should be between the priest and the throne, between the priestly and kingly offices of Jesus Christ. The peace and welfare of the gospel church, and of all believers, shall be wrought, though not by two several persons, yet by two several offices meeting in one; Christ, purchasing all peace by his priesthood, maintaining and defending it by his kingdom. The crowns used in this solemnity must be kept in the temple, as evidence of this promise of the Messiah. Let us not think of separating what God has joined in his counsel of peace. We cannot come to God by Christ as our Priest, if we refuse to have him rule over us as our King. We have no real ground to think our peace is made with God, unless we try to keep his commandments.
Matthew Henry's Commentary on Psalm 110:2
Glorious things are here spoken of Christ. Not only he should be superior to all the kings of the earth, but he then existed in glory as the eternal Son of God. Sitting is a resting posture: after services and sufferings, to give law, to give judgment. It is a remaining posture: he sits like a king for ever. All his enemies are now in a chain, but not yet made his footstool. And his kingdom, being set up, shall be kept up in the world, in despite of all the powers of darkness. Christ's people are a willing people. The power of the Spirit, going with the power of the world, to the people of Christs, is effectual to make them willing. They shall attend him in the beautiful attire of holiness; which becomes his house for ever. And he shall have many devoted to him. The dew of our youth, even in the morning of our days, ought to be consecrated to our Lord Jesus. Christ shall not only be a King, but a Priest. He is God's Minister to us, and our Advocate with the Father, and so is the Mediator between God and man. He is a Priest of the order of Melchizedek, which was before that of Aaron, and on many accounts superior to it, and a more lively representation of Christ's priesthood. Christ's sitting at the right hand of God, speaks as much terror to his enemies as happiness to his people. The effect of this victory shall be the utter ruin of his enemies. We have here the Redeemer saving his friends, and comforting them. He shall be humbled; he shall drink of the brook in the way. The wrath of God, running in the curse of the law, may be considered as the brook in the way of his undertaking. Christ drank of the waters of affliction in his way to the throne of glory. But he shall be exalted. What then are we? Has the gospel of Christ been to us the power of God unto salvation? Has his kingdom been set up in our hearts? Are we his willing subjects? Once we knew not our need of his salvation, and we were not willing that he should reign over us. Are we willing to give up every sin, to turn from a wicked, insnaring world, and rely only on his merits and mercy, to have him for our Prophet, Priest, and King? and do we desire to be holy? To those who are thus changed, the Saviour's sacrifice, intercession, and blessing belong.
