出埃及記 25:22 猶太思想：Akeidat Yitzchak & Guide for the Perplexed

1) The minimum dimensions of seven by seven handbreadths by a height of ten handbreadths, suggest that man should make do with the very minimum in earthly comforts.

You will perhaps ask this question: among the different degrees of prophecy there is one in which prophets, e.g., Isaiah, Micaiah, appear to hear God addressing them; how can this be reconciled with the principle that all prophets are prophetically addressed through an angel, except Moses our Teacher, in reference to whom Scripture says, “Mouth to mouth I speak to him” (Num. 12:8)? I answer, this is really the case, the medium here being the imaginative faculty that hears in a prophetic dream God speaking; but Moses heard the voice addressing him “from above the covering of the ark from between the two cherubim” (Exod. 25:22) without the medium of the imaginative faculty. In Mishne-torah we have given the characteristics of this kind of prophecy, and explained the meaning of the phrases, “Mouth to mouth I speak to him”; “As man speaketh to his neighbour” (Exod. 33:11), and the like. Study it there, and I need not repeat what has already been said.
