Zechariah 6:13 - Matthew Poole's English Annotations on the Holy Bible

Even he shall build: the promise is repeated to settle the Jews in the assured expectation of the thing. The temple of the Lord; your material temple as type, and the spiritual temple as antitype. He shall bear the glory of both kingly office and priestly, the glory of both those crowns shall abide on him, the only person worthy of it. He shall sit; which speaks both his royal magnificence and the perpetuity of it. And rule; though he shall have many attendants and officers, yet he shall rule, give laws, distribute rewards, and punish offenders. Upon his throne; his by birth, by donation, by purchase, and by conquest, his most undoubtedly by best right. He shall be a priest; the great High Priest, to offer the great sacrifice to God, to make reconciliation, to intercede for his people: this is that meant by the crowns set on thy head, O Joshua. The counsel of peace shall be between them both; the peace made for God's people shall rest upon these two, the kingly and priestly office of Christ: by his priestly office he shall make their peace with God, by his kingly office he shall deliver them from spiritual enemies; by priestly operation he shall expiate our sin, by the power of his kingly office he shall extirpate sin; as Priest he makes, as King maintains, peace; purchase as a Priest, protect as a King.
