民數記 26:2 註釋：Rashi, Rabbeinu Bahya, Chizkuni & Tur HaArokh

לבית אבתם [TAKE THE SUM OF THE CONGREGATION] ACCORDING TO THEIR FATHERS’ HOUSE — after their fathers’ tribes shall they reckon their descent, and not after their mothers’ (Bava Batra 109b).

שאו את ראש, “take a census.” Our sages (Tanchuma Pinchas 4) explained the reason for this census at this time by means of a parable. A shepherd whose flock had been attacked by wolves which had killed many of his sheep counted the surviving sheep in order to assess his losses. Furthermore, seeing that Moses had counted the people shortly after the Exodus, now that he was close to the end of his career he wanted to prove that he had the same number of people at his command to hand over to his successor.

שאו את ראש כל עדת בני ישראל, “take the sum of all the congregation of Israel from twenty years old and up;” once the count had been completed the Torah continues (verse 53) “to these the land will be divided up.” It describes that the amount of or quality of the various parts of the country will vary with the size of each tribe, so that it will be distributed fairly. (Numbers 26,54)
