Comentario sobre Números 7:85

שלשים ומאה הקערה אחת וגו׳ EACH CHARGER OF SILVER WEIGHING AN HUNDRED AND THIRTY SHEKELS etc. — Why is this stated at all since it has already been staled several times? But because it has only been said “the weight thereof was 130 shekels”, but it does not explain according to which shekel this is reckoned, it (Scripture) therefore repeats it (the number of shekels) here and then makes a general statement with regard to all of them: “all the silver of the vessels was [two thousand and four hundred shekels] after the shekels of the Sanctuary”.

By which shekel standard. Meaning that if not for this verse one would have said that the “holy shekel” written regarding the bowl referred to it alone. Therefore it wrote “one hundred thirty [shekolim was the weight of] each tray…”

כל כסף הכלים ALL THE SILVER OF THE VESSELS [WAS TWO THOUSAND AND FOUR HUNDRED SHEKELS etc.] — By giving the sum total of the shekels it teaches you that the vessels of the Sanctuary had their weight exact (thus e.g. a bowl of 70 shekels was exactly 70, neither more nor less) — whether one weighed them each separately or whether one weighed them all together he got neither more nor less than it should have been ( Sifrei Bamidbar 54).

Precision. Meaning that each one was precisely the weight of the other, even though the scales of an individual do not normally weigh exactly, however the Sanctuary vessels were exactly the same. It appears to me that the reason was to show that even though the thoughts of each leader were directed towards his tribe, as Rabbeinu Bachaye writes in this Parshah, the volumes and the weights were equal to show that they all intended them for the same God.
