Numbers 12:8

פה אל פה MOUTH TO MOUTH [I HAVE SPOKEN WITH HIM] — I have Myself told him to separate from his wife. And where did I tell him this? On Sinai, when I said to him, (Deuteronomy 5:27 Deuteronomy 5:28) “Go, say to them (to the people), ‘Get you into your tents (rejoin your wives). But as for thee, remain thou here by Me, [and I will speak unto thee]’” (Shabbat 87a; cf. Sifrei Bamidbar 103). ומראה ולא בחידת AND IN A מראה AND NOT IN RIDDLES — When it says מראה, this refers to the clearness of the Divine communication, i.e. that I express My communication unto him in the clearest form in which it can be put and do not obscure it in riddles, as e.g. was the manner in which it was said to Ezekiel: (Ezekiel 17:2), “Put forth a riddle etc.” — One might, however, think that it refers to the “appearance of the Shechinah” (i.e. that he saw God)! It, however, states, (Exodus 33:20) “Thou cannot see My face” (Sifrei Bamidbar 103). ותמנת ה' יביט AND THE SIMILITUDE OF THE LORD DID HE BEHOLD — This refers to beholding the after-effects of God’s Providence, just as it is stated, (Exodus 33:22 Exodus 33:23) “[And it shall be when My glory passeth by] thou shalt see what is behind Me” (Sifrei Bamidbar 103). בעבדי במשה [WHY WERE YE NOT AFRAID TO SPEAK] AGAINST MY SERVANT, AGAINST MOSES — It does not state “against My servant Moses”, but “against My servant, against Moses”, which suggests: why were ye not afraid to speak against My servant, even though he were not a Moses; and why were ye not afraid to speak against a Moses — even though he were not My servant — in either of these cases you ought to have feared him! How much the more ought you to be afraid to speak against him (Moses) he being also My servant — and the servant of a king is a king (a noble person) himself! You should have said: The King does not love him without reason! — But if you reply that I am not cognizant of his doings (i. e. that I love him though he does not deserve it, since I am not aware of his treatment of his wife) — then this statement is even worse than your previous one (Midrash Tanchuma, Tzav 13; cf. Sifrei Bamidbar 103).

פֶּ֣ה אֶל־פֶּ֞ה אֲדַבֶּר־בּ֗וֹ וּמַרְאֶה֙ וְלֹ֣א בְחִידֹ֔ת וּתְמֻנַ֥ת יְהֹוָ֖ה יַבִּ֑יט וּמַדּ֙וּעַ֙ לֹ֣א יְרֵאתֶ֔ם לְדַבֵּ֖ר בְּעַבְדִּ֥י בְמֹשֶֽׁה׃

With him I speak mouth to mouth, manifestly, and not in dark speeches; and the similitude of the Lord does he behold: why then were you not afraid to speak against my servant Moshe?
