Likutei Halakhot, Orach Chaim, Laws of the New Moon 7:16/ליקוטי הלכות·אורח חיים·הלכות ראש חדש ז׳:ט״ז

1As the essence of the tabernacle is the aspect of completing the Torah, the aspect of the tablets of stone that sat in the ark, from which all of the holiness of the tabernacle and the Temple [derives]. For they dedicated it for this - in order to rectify the damage of the mixed multitude who made the [golden] calf, by way of their damaging faith in the sages. For they did not have faith in Moshe our teacher and Aharon, etc. And because of that, the tablets were broken. And now the tabernacle was built for the sake of this rectification, like our Rabbis, may their memory be blessed, said. That is why they dedicated it according to the plan of the Children of Issachar, who were experts in the secret of intercalation (sod haibur). For this is the aspect of the rectification of faith in the sages, in order to bring down through these sacrifices the aspect of the rectification of the proliferation of holy books which complete the Torah. That is to be in the aspect of the complete tablets of stone, to rectify the damage of the breaking of the tablets. For it was in the tabernacle that Moshe our teacher received the Torah, as Rashi explains. As from the day the Tent of Meeting was established, He only spoke with him from there. And that was the entire essence of the holiness of the Tent of Meeting with the sacrifices that were offered there: It was all in order to atone for the Jewish people and to have them merit repentance for the damage to faith in the sages. For the entire sin of the calf came from that, as mentioned above. And because of this, the twelve chieftains dedicated it with the plan of Netanel, who was an expert in the secret of intercalation, as mentioned above. That is why we read all of this on Chanukah. For we then need to subdue the denial of true sages by the aspect of Greek wisdoms; and to draw forth the rectification of faith in the sages, through the great light of the Torah, which shines with the proliferation of holy books, as mentioned above.
