On The Position of וְעָשׂוּ לִי, מִקְדָּשׁ; וְשָׁכַנְתִּי, בְּתוֹכָם

The "new" commandment וְעָשׂוּ לִי, מִקְדָּשׁ; וְשָׁכַנְתִּי, בְּתוֹכָם is the second one of the ten commandments. Indeed, a description of the Shabbat is preceded by a description of Pesach in Parashat Ki Boshesh. However, in Parshat Mishpatim, Shabbat appears before the three Regalim. Hence, the fourth position should be considered for וְעָשׂוּ לִי, מִקְדָּשׁ; וְשָׁכַנְתִּי, בְּתוֹכָם. It could be that Chet HaEgel had an influence, and it became the second commandment only after the Sin.
