Zechariah 3:5

And I said: Zechariah takes the boldness to desire that for Joshua which might add to his veneration and authority; and he asks the thing of Christ, or rather Christ commandeth this be done. Let them, who minister before Christ, set a fair mitre; a rich and beautiful ornament for the head of the high priest; not a crown, which is for royal heads, but a tire, a pontifical ensign. So they set, as they were commanded by Christ at the request of the prophet. And clothed him with garments; all the garments which did appertain to the high priest, of which you read Exodus 28:4, which probably were put on, though they are not expressly mentioned here. The angel, who is the Lord Christ himself, stood by; withdrew not till all this was done.
