וידבר… במדבר סיני … באחד לחדש וגו׳ AND [THE LORD] SPOKE [UNTO MOSES] IN THE DESERT OF SINAI … ON THE FIRST DAY OF THE [SECOND] MONTH … [TAKE YE THE SUM OF ALL THE CONGREGATION] etc. — Because they were dear to him, He counts them every now and then: when they went forth from Egypt He counted them (Exodus 12:37), when many of them fell in consequence of their having worshipped the golden calf He counted them to ascertain the number of those left (cf. Rashi Exodus 30:16); when he was about to make His Shechinah dwell amongst them (i. e. when He commanded them to make a Tabernacle), He again took their census; for on the first day of Nisan the Tabernacle was erected (Exodus 40:2) and shortly afterwards, on the first day of Iyar, He counted them.

למשפחתם — [TAKE YE THE SUM OF THE CONGREGATION …] AFTER THEIR FAMILIES — in order to ascertain the number of individuals in each tribe.

לבית אבתם BY THE HOUSE OF THEIR FATHERS — One whose father belongs to one tribe and his mother to another tribe shall take his stand with the tribe of his father (cf. Bava Batra 109b).

לגלגלתם BY THEIR POLLS — i. e. by means of shekels — “a beka a head (לגלגלת)”, as was prescribed on a previous occasion (Exodus 38:26).

כל יצא צבא [FROM TWENTY YEARS OLD AND UPWARDS] ALL THAT GO FORTH TO THE HOST — This tells us that no one less than twenty years of age goes forth to the host (cf. Rashi on Exodus 30:14 and Note thereon).

ואתכם יהיו AND WITH YOU THERE SHALL BE [A MAN OF EVERY TRIBE] — when you number them there shall be with you the princes of each tribe.

אלה קרואי העדה THESE WERE THOSE CALLED OF THE CONGREGATION — those who were called upon for every matter of importance that happened in the congregation.

האנשים האלה [AND MOSES AND AARON] TOOK THESE MEN — these twelve princes.

אשר נקבו WHO WERE MENTIONED to him (Moses) here בשמות BY NAME.

ויתילדו על משפחותם THEY DECLARED THEIR PEDIGREES AFTER THEIR FAMILIES — They brought the records of their pedigree and witnesses to confirm the prevalent presumption regarding their parentage, so that each might establish his pedigree with regard to the particular tribe (cf. Yalkut Shimoni on Torah 684).

אך את מטה לוי לא תפקד ONLY THOU SHALT NOT NUMBER THE TRIBE OF LEVI — The legion of the King is worthy to be numbered by itself (cf. Midrash Tanchuma, Bamidbar 15). — Another explanation is: The Holy One, blessed be He, foresaw that a decree would once be made against all those that had been numbered from twenty years and upwards, viz., that they should die in the wilderness (Numbers 14:29). He therefore said: Let these (the Levites) not be included amongst those now counted, in which case they must die, because they are Mine, since they did not sin by worshipping the golden calf (cf. Numbers Rabbah 3:7; Bava Batra 121b).

ואתה הפקד את הלוים BUT THOU SHALT APPOINT THE LEVITES OVERSEERS [OVER THE TABERNACLE etc.] — Understand the word הפקד as the Targum does: ,מני “appoint”; it (the word מני) is an expression for appointing a person to control that thing over which he has been appointed; similar is, (Esther 2:3) “and let the king appoint (ויפקד) officers”.

יורידו אתו [AND WHEN THE DWELLING SETTETH FORWARD] THE LEVITES SHALL TAKE IT DOWN — Understand יורידו as the Targum does: they shall take it apart. Whenever they were about to set out on a journey in the wilderness from one station to another (cf. Rashi Exodus 40:38) they took the structure apart (lit., they took it apart from its state of being put up) and carried it to the place where the cloud afterwards abode, and there they encamped and erected it (the Tabernacle).

והזר הקרב AND THE LAYMAN THAT COMETH NIGH to this service of theirs,

יומת SHALL BE PUT TO DEATH by heaven (not by sentence of the court) (cf. Sanhedrin 84a).

ואיש על דגלו [AND THE CHILDREN OF ISRAEL SHALL ENCAMP, EVERY MAN BY HIS OWN CAMP] AND EVERY MAN BY HIS OWN STANDARD, just as the order of the banners is given in this Book (Numbers) — three tribes for every banner.

ולא יהיה קצף THAT THERE BE NO ANGER [UPON THE CONGREGATION] — If you act according to My commands there will be no anger, but if not, — i.e., that strangers take part in this their (the Levites’) service, there will be anger, just as we find at the incident with Korah (Numbers 17:11): “for there is anger gone forth [from the Lord]”.
