שמות

ויקם משה את המשכן. דרשו רז"ל בפרק שתי הלחם מעלין בקדש ואין מורידין, מעלין בקדש מנין מן המחתות של עדת קרח שנעשו צפוי למזבח, ולא מורידין מן הכתוב הזה ויקם משה את המשכן ויקם את אדניו שהרי כמה פעמים ביום שהיה משה מקימן היה מפרקן ולא הזכיר בפירוש שיאמר בשום מקום ויורד משה את המשכן אלא ויקם.

ויקם משה את המשכן, “Moses erected the Tabernacle, etc.” Our sages in Menachot 99 taught that one increases or adds to levels of holiness and never decreases them. They derive the first half of their statement from the censers of the people who had supported the rebellion of Korach and offered incense in them. G’d commanded that theses censers of the 250 men who had paid with their lives for their mistake be subsequently used to make a copper cover for the main altar in the courtyard of the Tabernacle (compare Numbers 17,3). The rule that levels of sanctity are not to be reduced is derived from our verse here. The Torah writes the following sequence: “Moses erected the Tabernacle; he put down its sockets and emplaced its boards and inserted its bars and erected its pillars. The wording indicates that Moses repeated this procedure many times over; the Torah carefully refrains from mentioning that he “dismantled” any part of the Tabernacle in the process. Only actions which resulted in additional sanctity are spelled out.
