לֹא־כֵ֖ן עַבְדִּ֣י מֹשֶׁ֑ה בְּכָל־בֵּיתִ֖י נֶאֱמָ֥ן הֽוּא׃
Мой слуга Моисей не так; ему доверяют во всем доме Моем;
Ibn Ezra
In My entire house — as a member of the household, who may enter without permission, and if he needs something he can speak about it anytime. To Aharon and Miriam, on the other hand, Hashem would only reveal Himself in a dream, and if not, they had no permission to ask.
Rashbam
נאמן הוא, a permanent presence, belonging to the foundation at any time of the day. The word נאמן occurs in this sense of Isaiah 22,23 יתד במקום נאמן, “as a peg in a firm place.” It is something that is not apt to fall down.
Sforno
לא כן עבדי משה, who experiences that G’d the Essence (hashem) speaks to him while he is awake.
