(ב) וכן תעשו. לַדוֹרוֹת (סנהדרין ט"ז), אִם יֹאבַד אֶחָד מִן הַכֵּלִים, אוֹ כְּשֶׁתַּעֲשׂוּ לִי כְּלֵי בֵית עוֹלָמִים:
(2) וכן תעשו AND SO SHALL YE MAKE IT also in future generations (cf. Sanhedrin 16b); if one of the vessels is lost, or when you make for Me the vessels for the “House of Eternity”
(9) You shall take the anointing oil and anoint the Tabernacle and all that is in it to consecrate it and all its furnishings, so that it shall be holy.
מתיב רבא כל הכלים שעשה משה משיחתן מקדשן מיכן ואילך עבודתן מחנכתן
Rava raises an objection from a baraita: With regard to all of the utensils that Moses fashioned, their anointment with the sacred oil is what consecrates them. From that point forward, there is no need for anointment, but rather their service in and of itself dedicates them
(יב) כָּל כְּלֵי הַמִּקְדָּשׁ שֶׁעָשָׂה משֶׁה בַּמִּדְבָּר לֹא נִתְקַדְּשׁוּ אֶלָּא בִּמְשִׁיחָתָן בְּשֶׁמֶן הַמִּשְׁחָה שֶׁנֶּאֱמַר (במדבר ז א) "וַיִּמְשָׁחֵם וַיְקַדֵּשׁ אֹתָם". וְדָבָר זֶה אֵינוֹ נוֹהֵג לְדוֹרוֹת. אֶלָּא הַכֵּלִים כֻּלָּן כֵּיוָן שֶׁנִּשְׁתַּמְּשׁוּ בָּהֶן בַּמִּקְדָּשׁ בִּמְלַאכְתָּן נִתְקַדְּשׁוּ שֶׁנֶּאֱמַר (במדבר ד יב) "אֲשֶׁר יְשָׁרְתוּ בָם בַּקֹּדֶשׁ" בְּשֵׁרוּת הֵם מִתְקַדְּשִׁין:
All of the vessels of the Sanctuary that were fashioned [at the command] of Moses were sanctified only by being anointed with the anointing oil, as [Numbers 7:1] states: "And he anointed them and sanctified them." This practiced was not followed in the coming generations. Instead, all of the utensils became sanctified when they were used for their purpose in the Temple, as [implied by Numbers 4:12] "...that they will serve with them in the Sanctuary," i.e., through service, they are sanctified.
The Ralbag explains that the Ark represented the Torah. The Torah is perfect. Therefore, the Ark must always be perfect. With the removal of the poles, the Ark would no longer be complete. An incomplete Aron is unfit to represent the Torah.
