And he shewed me Joshua the high priest standing before the angel of the LORD, and Satan standing at his right hand to resist him. And he showed me Joshua the high priest - The Angel of the Lord is the Messiah, as we have seen before; Joshua, the high priest, may here represent the whole Jewish people; and Satan, the grand accuser of the brethren. What the subject of dispute was, we perhaps learn from Jde 1:9. Michael and Satan disputed about the body of Moses. This could not refer to the natural body of the Jewish lawgiver, which had been dead about owe thousand years; it must therefore refer to that body of laws given to the Jews by Moses, for the breach of which Satan, who was their tempter to disobedience, now comes forward as their accuser; that, exciting the justice of God against them, they may be all brought to perdition. There is a paronomasia here: -
Satan standing at his right hand to resist him - שטן Satan signifies an adversary. לשטנו lesiteno, to be his adversary, or accuser.
