바미드바르 (민수기) 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”. 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).

שְׁלֹשִׁ֣ים וּמֵאָ֗ה הַקְּעָרָ֤ה הָֽאַחַת֙ כֶּ֔סֶף וְשִׁבְעִ֖ים הַמִּזְרָ֣ק הָאֶחָ֑ד כֹּ֚ל כֶּ֣סֶף הַכֵּלִ֔ים אַלְפַּ֥יִם וְאַרְבַּע־מֵא֖וֹת בְּשֶׁ֥קֶל הַקֹּֽדֶשׁ׃

each dish of silver weighing a hundred and thirty shekels, each bowl seventy: all the silver vessels weighed two thousand four hundred shekels, after the shekel of the sanctuary:
