Numbers 7:1

ויהי ביום כלות משה AND IT CAME TO PASS ON THE DAY THAT MOSES HAD FINISHED [RAISING THE TABERNACLE] — The word כלות is written defective (without ו after the ל) thus indicating: on the day that the Tabernacle was erected Israel was like a bride (כלה) who goes beneath the marriage canopy (Midrash Tanchuma, Nasso 20). (Cf. Rashi on Exodus 31:18.) כלות משה MOSES HAD FINISHED — Bezalel and Ohaliab and all the wise-hearted men made the Tabernacle (cf. Exodus 36:1), but Scripture attributes it to Moses (describes it as his work), because he devoted himself wholeheartedly to it, to see that the shape of each article was exactly as He had shewn him on the mountain — to show the workmen how it should be made; nor did he err in a single shape. — A similar thing do we find in the case of David: because he devoted himself to the building of the Holy Temple, — as it is said, (Psalms 132:1—5) “Lord, remember David, and all his affliction: How he swore unto the Lord … [I will not give sleep to mine eyes … until I find out a place for the Lord …]”, therefore it is called by his name, as it is said, (1 Kings 12:16) “Now see your own house, David" (Midrash Tanchuma, Nasso 13). כלות משה להקים [AND IT CAME TO PASS ON THE DAY] THAT MOSES HAD FINISHED SETTING UP [THE TABERNACLE] — but it is not said, “on the day Moses set up”; this (the phrase כלות … להקים, “had finished setting up”) teaches us that during each of the seven days of installation Moses used to erect and dismantle it (the Tabernacle), but on that day (the eighth) he erected it but did not again dismantle it; for this reason it is said: “on the day that (Moses) finished setting up” — i.e. on that day his several erections of it came to an end. — It was the New Moon (the first day) of Nisan (cf. Rashi on Leviticus 9:1 and Note thereon), on the second the Red Heifer was burnt, on the third they (the Levites) were sprinkled for the first time with the water in which its ashes were mingled (cf. Rashi on 8:7), and on the seventh day, after having been again sprinkled, they shaved their bodies and were ready to enter on their duties (cf. 8:6—7) (Sifrei Bamidbar 44).

And it came to pass on the day that Moshe had finished setting up the tabernacle, and had anointed it, and sanctified it, and all its instruments, both the altar and all its vessels, and had anointed them, and sanctified them;
