(4) Exodus 25:9.“Exactly as I show you—the pattern of the Tabernacle and the pattern of all its furnishings—so shall you make it." Rashi comments on so shall you make it -- for all generations. Tosfot object: The altar that Moses made was not equal to that made by Solomon! Nachmanides raises a similar objection.
But following our method, we ca understand so shall you make it as referring to something else. Really, the structure of the Tabernacle and all its vessels that had to be of a certain height, weight, and form were all ways of garbing or giving form to some holy spiritual entity. This followed the prophetic vision that Moses had on Mount Sinai, along with all of Israel. As they drew this holy inspiration into their deeds, so it was. This was the way that the garb or vessel, along with the Tabernacle itself, had to be made.
But we also know the Talmudic statement that "no two prophets prophecy in the same style" (b. Sanhedrin 89a). Each does so in his own categories. These follow the path of that person in worshipping God; in that very way does the spirit of prophecy appear to him. This means that Moses and the generation of the wilderness, following the qualities of worship and prophecy they attained at Sinai, had to construct this particular form of Tabernacle, structuring its vessels in just this way so that they would properly garb the spiritual lights of holiness. This is what the Torah means when it says: Exactly as I show you -- according to your framework of prophecy, so should the Tabernacle and vessels be.
Then Torah adds: so shall you make it -- for all generations. This means that in every generation, when you want to build the Temple, this structure should be in accord with the prophecy that is attained at that time. That should determine the form of the Temple and vessels. Solomon did it according to this own worship and his prophetic spirit. The for he made followed that which he attained.
Thus Nachmanides' objection can really be dismissed. Of course his altar was different! That was the commandment -- that they not do it always in one particular form, but in accord with the flow of prophecy that takes place then. That should determine the form of the earthly vessels.
