John Trapp on Zechariah 6:9

Verſe 9. And the word of the Lord came unto me ſaying,] This ſecond part of the Chapter, is not a viſion, but a Sermon, or an hiſtoricall prediction of what was really to be done. For as Gods Spirit was quieted, and as it were comforted by the Angels faithfull execution of their offices: ſo He ſeeks by this Prophecy, to quiet and comfort the ſpirits of his people the Iews, that were returned out of Babylon. For theſe finding themſelves beſet with enemies, and exigencies, might poſſibly deſpair of ever ſeeing the accompliſhment of thoſe promiſes and prophecies of the kingdome reſtored to the houſe of David, and of the great glory of the ſecond Temple above the firſt. To keep up their hearts therefore, is this declaration made them of the kingdome and prieſtood of Chriſt, under the typicall coronation of Jehoſhuah the High-prieſt.
