John Trapp on Zechariah 3:5

Verſe 5. And I ſaid, let them ſet a fair mitre upon his head] Who ſaid this? The Prophet, grounding his ſpeech on the laſt gracious words of the Angel, taketh the boldneſſe to enterpoſe this his requeſt for the beſtowing of the prieſtly ornaments upon Joſhua, and accordingly it is done. This the prophet knew would be a comfort to the whole people, and a confirmation to Ioſhuas faith, for the pardon of his ſins: like as it was to Peter and the reſt of the Apoſtles,Mat. 28.19. Joh. 20.21. that Chriſt after his reſurrection reſtored them to their office, after they had all ſhamefully forſaken him.

let them ſet a fair mitre upon his head] Not a diadem, as the old Tranſlation hath it (that's for a kings head) much leſſe a triple crown with the word Myſtery (Babylons motto Rev. 17.5.) engraven in it, as Brocard and many other eye-witneſſes affirm of the Popes crown but a Mitre or tiar. It hath its name from compaſſing about, be cauſe it invironed the High-prieſts head. It had a holy crown with it Exod. 29.6. ſignifying the Deity and dignity of Chriſt. It had alſo upon the fore-front of it a plate of pure gold with this caelature, Holineſſe to the Lord. Hence it was not lawful for the High prieſt, (ſay the Jews) to put off his mitre to whomſoever he met, were he never ſo great a man: leſt the name and glory of God (whoſe perſon he ſuſtained) ſhould ſeem to ſubmit to any living: With this Myſterious mitre upon his head, with other prieſtly Ornaments and veſtments it was, that Alexander the greatmet the High-prieſt Iaddus (Nephew and ſucceſſour to Ichoſhuah in the text) as he was ma[illegible: 1 letter]ching againſt Jeruſalem with hoſtile intent: and adoring that God whoſe name was ſeen written on the golden plate of his Mitre, he entered the city peaceably, offered ſacrifice in the Temple, as the Prieſts directed him,Dan. 8.7, 20, 21. & 11, 13. and having ſeen there the propheſie of Daniel concerning himſelf, he granted the Jews many immunities and priviledges, and ſo departed. Parmenio, one of his favorites, asked him the reaſon of his friendly dealing with the Jews, [illegible: 1 letter]ſeph. lib. 11. Cap. vlt. who by denying him help and tribute had highly diſpleaſed him: He anſwered, that while he was yet in Macedonia, and but thinking of the conqueſt of Aſia, a certain man appeared unto him in the habit of that High-prieſt encouraging him to ſet upon the work, and aſſuring him of good ſucceſſe therein.

and the Angel of the Lord] that is Chriſt, the Maſter of theſe Ceremenies, the effect of this Levitical office.
