Commentaire sur Les Nombres 12:7

לא כן עבדי משה, who experiences that G’d the Essence (hashem) speaks to him while he is awake.

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.

לא כן עבדי משה בכל ביתי נאמן הוא , “not so is My servant Moses who is trusted in My entire house.” Hashem describes Moses as a father would describe his own son, or anyone whom he had adopted as part of his family. Just as such children have unrestricted access to any part of their father’s house at any time, so Moses does not need to make appointments if he wants to discuss something with Hashem. You, however, G’d says to Aaron and Miriam, not only do you not always have access to My house, but even when you do enjoy communications from Me, it is on a different level from the way I communicate with Moses.
