The beginning of the Parsha opens up with building the Mishkan
(כא) אֵ֣לֶּה פְקוּדֵ֤י הַמִּשְׁכָּן֙ מִשְׁכַּ֣ן הָעֵדֻ֔ת אֲשֶׁ֥ר פֻּקַּ֖ד עַל־פִּ֣י מֹשֶׁ֑ה עֲבֹדַת֙ הַלְוִיִּ֔ם בְּיַד֙ אִֽיתָמָ֔ר בֶּֽן־אַהֲרֹ֖ן הַכֹּהֵֽן׃
(21) These are the records of the Tabernacle, the Tabernacle of the Pact, which were drawn up at Moses’ bidding—the work of the Levites under the direction of Ithamar son of Aaron the priest.
(ב) המשכן משכן. שְׁנֵי פְעָמִים, רֶמֶז לַמִּקְדָשׁ שֶׁנִּתְמַשְׁכֵּן בִּשְׁנֵי חֻרְבָּנִין עַל עֲוֹנוֹתֵיהֶן שֶׁל יִשְׂרָאֵל (תנחומא):
(2) המשכן משכן OF THE TABERNACLE, EVEN OF THE TABERNACLE — The word משכן is mentioned here twice in allusion to the Temple that was taken in pledge (משכן) — as it were — (as a security for Israel’s repentance) by being twice destroyed for Israel’s iniquities (Midrash Tanchuma, Pekudei 5).
(לג) וַיָּבִ֤יאוּ אֶת־הַמִּשְׁכָּן֙ אֶל־מֹשֶׁ֔ה אֶת־הָאֹ֖הֶל וְאֶת־כׇּל־כֵּלָ֑יו קְרָסָ֣יו קְרָשָׁ֔יו בְּרִיחָ֖ו וְעַמֻּדָ֥יו וַאֲדָנָֽיו׃
(33) Then they brought the Tabernacle to Moses, with the Tent and all its furnishings: its clasps, its planks, its bars, its posts, and its sockets;
(א) ויביאו את המשכן וגו'. שֶׁלֹּא הָיוּ יְכוֹלִין לַהֲקִימוֹ; וּלְפִי שֶׁלֹּא עָשָׂה מֹשֶׁה שׁוּם מְלָאכָה בַמִּשְׁכָּן, הִנִּיחַ לוֹ הַקָּבָּ"ה הֲקָמָתוֹ, שֶׁלֹּא הָיָה יָכוֹל לַהֲקִימוֹ שׁוּם אָדָם מֵחֲמַת כֹּבֶד הַקְּרָשִׁים, שֶׁאֵין כֹּחַ בָּאָדָם לְזָקְפָן, וּמֹשֶׁה הֶעֱמִידוֹ; אָמַר מֹשֶׁה לִפְנֵי הַקָּבָּ"ה אֵיךְ אֶפְשָׁר הֲקָמָתוֹ עַ"יְ אָדָם? אָמַר לוֹ עֲסֹק אַתָּה בְּיָדְךָ, וְנִרְאֶה כִּמְקִימוֹ וְהוּא נִזְקָף וְקָם מֵאֵלָיו, וְזֶהוּ שֶׁנֶּ' הוּקַם הַמִּשְׁכָּן (שמות מ') – הוּקַם מֵאֵלָיו; מִדְרַשׁ רַ' תַנְחוּמָא:
(1) ויביאו את המשכן וגו׳ AND THEY BROUGHT THE TABERNACLE [UNTO MOSES etc.], for they themselves were unable to erect it. Since Moses had done no work in the Mishkan, the Holy One, blessed is He, left for him the task of erecting it, for nobody was able to set it up because of the weight of the boards which no human strength was capable of setting up. Moses, however, succeeded in placing it in position. Moses said to the Holy One, blessed be He, “How is its erection possible by human beings?” God answered him: “You be busy with your hand!” He appeared to be erecting it, but in fact it set itself up and rose of its own accord. That is why Scripture says, (Exodus 40:17) “The Tabernacle was erected (הוקם)” — was erected by itself. This is a Midrash of Rabbi Tanchuma 2:11:11.
