Adam Clarke on Zechariah 3:2

Is not this a brand plucked out of the fire? - The Jews were nearly destroyed because of their sins; a remnant of them is yet left, and God is determined to preserve them. He has had mercy upon them, and forgiven them their sins. Wouldst thou have them destroyed? It is God that hath justified them; who art thou that condemnest them? The Lord rebuke thee! God confound thee for what thou hast done, and for what thou desirest farther to do! It is evident that Jde 1:9 relates to this circumstance - the very same phraseology which occurs here. See the notes on Jde 1:9, where the subject is largely considered. With difficulty has this remnant escaped, and God will not permit fresh evils to fall upon them, by which they might be totally consumed. This was Satan's design, who accuses the followers of God day and night. See Rev 12:10.
