3:1-5 The angel showed Joshua, the high priest, to Zechariah, in a vision. Guilt and corruption are great discouragements when we stand before God. By the guilt of the sins committed by us, we are liable to the justice of God; by the power of sin that dwells in us, we are hateful to the holiness of God. Even God's Israel are in danger on these accounts; but they have relief from Jesus Christ, who is made of God to us both righteousness and sanctification. Joshua, the high priest, is accused as a criminal, but is justified. When we stand before God, to minister to him, or stand up for God, we must expect to meet all the resistance Satan's subtlety and malice can give. Satan is checked by one that has conquered him, and many times silenced him. Those who belong to Christ, will find him ready to appear for them, when Satan appears most strongly against them. A converted soul is a brand plucked out of the fire by a miracle of free grace, therefore shall not be left a prey to Satan. Joshua appears as one polluted, but is purified; he represents the Israel of God, who are all as an unclean thing, till they are washed and sanctified in the name of the Lord Jesus, and by the Spirit of our God. Israel now were free from idolatry, but there were many things amiss in them. There were spiritual enemies warring against them, more dangerous than any neighbouring nations. Christ loathed the filthiness of Joshua's garments, yet did not put him away. Thus God by his grace does with those whom he chooses to be priests to himself. The guilt of sin is taken away by pardoning mercy, and the power of it is broken by renewing grace. Thus Christ washes those from their sins in his own blood, whom he makes kings and priests to our God. Those whom Christ makes spiritual priests, are clothed with the spotless robe of his righteousness, and appear before God in that; and with the graces of his Spirit, which are ornaments to them. The righteousness of saints, both imputed and implanted, is the fine linen, clean and white, with which the bride, the Lamb's wife, is arrayed, Re 19:8. Joshua is restored to former honours and trusts. The crown of the priesthood is put on him. When the Lord designs to restore and revive religion, he stirs up prophets and people to pray for it.
5. And I said—Here the prophet, rejoicing at the change of raiment so far made, interposes to ask for the crowning assurance that the priesthood would be fully restored, namely, the putting the miter or priestly turban on Joshua: its fair color symbolizing the official purity of the order restored. He does not command, but prays; not "Set," but "Let them set." Vulgate and Syriac version read it, "He then said," which is the easier reading; but the very difficulty of the present Hebrew reading makes it less likely to come from a modern corrector of the text.
angel of … Lord stood by—the Divine Angel had been sitting (the posture of a judge, Da 7:9); now He "stands" to see that Zechariah's prayer be executed, and then to give the charge (Zec 3:6, 7).
