וַיַּרְאֵ֗נִי אֶת־יְהוֹשֻׁ֙עַ֙ הַכֹּהֵ֣ן הַגָּד֔וֹל עֹמֵ֕ד לִפְנֵ֖י מַלְאַ֣ךְ יְהוָ֑ה וְהַשָּׂטָ֛ן עֹמֵ֥ד עַל־יְמִינ֖וֹ לְשִׂטְנֽוֹ׃
And he showed me Joshua the high priest standing before the angel of the LORD, and Satan standing at his right hand to accuse him.
Shemirat HaLashon
And all of this was alluded to in the verse concerning Yehoshua ben Yehotzadak, the high-priest, viz. (Zechariah 3:1): "And He showed me Yehoshua the high-priest standing before the angel of the L-rd. And the Satan was standing on his right, to accuse him… (4) …Remove the dungy vestments from him [Yehoshua]." The "dungy vestments" connote the uncleanliness of transgressions, which are as repulsive as dung. And "Remove … from him" indicates that he was clothed in them against his will. And this is what Scripture tells us tersely in (Vayikra 11:43): "Do not make yourselves unclean in them, lest you become unclean through them."
