Joshua is pictured standing before the face of the angel of the Lord who (as before) is the Second Person of the Godhead. Satan is there to “resist” (the same word) the angel of the Lord. “Satan” is a title—a noun to describe the character of an adversary. That Hebrew termsatan appears 30 times in Scripture, sometimes applying to human adversaries as well as that chief angelic being.
In this vision, Joshua appears in “filthy” clothing unfit to come before the presence of the Lord—a picture of the human sinful condition (Psalm 14:2-3; Isaiah 64:6). But, since Joshua is a “brand plucked from the fire” by the Lord Himself (Zechariah 3:2), Joshua has the filthy garments taken away and a change of clothing given.
Suddenly, the scene shifts as the angel of the Lord announces the promise of the Lord of hosts: “I will bring forth my servant the BRANCH. For behold the stone that I have laid before Joshua; upon one stone shall be seven eyes: behold, I will engrave the graving thereof, saith the LORD of hosts, and I will remove the iniquity of that land in one day” (Zechariah 3:8-9).
Many previous prophetic promises must have passed through Zechariah’s mind as he heard these words. Jeremiah spoke of a “Branch of righteousness” (Jeremiah 33:15-16). Isaiah promised the son who would rule the world (Isaiah 9:6-7). Even Hanani the seer spoke of “the eyes of the Lord” that would “shew himself strong” (2 Chronicles 16:9). These visions were given to encourage the returning remnant (and us) to reset their focus on the timeless promises of the everlasting God. HMM III
