Midrash sobre Números 18:20

Michael, the angel, descended and took Levi, and brought him up before the Throne of Glory, and he spake before Him: Sovereign of all || the universe ! This is Thy lot, and the portion of Thy works. And He put forth His right hand and blessed him, that the sons of Levi should minister on earth before Him, like the ministering angels in heaven. Michael spake before the Holy One, blessed be He: Sovereign of all worlds ! Do not such who serve the king have provision of their food given to them? Therefore He gave to the sons of Levi all holy things which accrue to His Name, as it is said, "They shall eat the offerings of the Lord made by fire, and his inheritance" (Deut. 18:1).

(Bamidbar 18:20) "And the L-rd said to Aaron: In their land you will not inherit, and you will not have a portion in their midst. I am your portion and your inheritance in the midst of the children of Israel.": Why is (all of) this stated? Because it is written (Bamidbar 26:53) "To these shall the land be apportioned," I would think that all are included — Cohanim, Levites, Israelites, proselytes, women, bondsmen, tumtum (those of uncertain sex) and androgynous (hermaphrodites); it is, therefore, written: "And the L-rd said to Aaron: In their land you will not inherit" — This excludes (from inheritance) Cohanim." (Ibid. 23) "And in the midst of the children of Israel, they (the Levites) shall not inherit an inheritance" — This excludes Levites. (Ibid. 26:55) "By the names of the tribes of their fathers shall they inherit" — This excludes bondsmen and proselytes (Ibid. 54) "A man, according to his numbers shall his inheritance be given" — This excludes tumtum and androgynous. (Ibid. 18:20) "And the L-rd said to Aaron: In their land you will not inherit" — in the division of the land. "and you will not have a portion in their midst" — ("a portion") of the spoils. "I am your portion and your inheritance" — At My table (i.e., from the sacrifices) you eat and at My table you drink. An analogy: A king gave gifts to (all of) his sons except one, saying to him: My son, I gave you a gift. At My table you eat and at My table you drink. And thus is it written (Vayikra 6:10) "Their portion have I given to them from My fire-offerings." (Devarim 18:1) "The fire-offering of the L-rd and His inheritance shall they eat." Twenty-four priestly gifts were given to the Cohanim, twelve in the sanctuary and twelve in the borders (i.e., outside of Jerusalem.) Twelve in the sanctuary: sin-offering, guilt-offering, the remnant of the log of oil of the leper, the remnant of the omer, the two loaves, the show-bread, the remnant of meal-offerings, the terumah of the thank-offering (viz. Vayikra 7:14), the terumah of breast and thigh, the shoulder of the ram of the Nazirite.

(Bamidbar 26:53) "To these shall the land be apportioned as an inheritance according to the number of names": I would understand that all are included — Israelites, Cohanim, Levites, proselytes, women, bondsmen, tumtumim (those of indeterminate sex), and hermaphrodites. It is, therefore, written (Ibid. 18:20) "And the L-rd said to Aaron: In their land you shall not inherit" — to exclude Cohanim. (Ibid. 24) "In the midst of the children of Israel they shall not have an inheritance" — to exclude Levites. (Ibid. 26:55) "By the names of the tribes of their fathers shall they inherit" — to exclude proselytes and bondsmen. (Ibid. 59) "To a man, according to his numbers, shall his inheritance be given" — to exclude women, tumtumim, and hermaphrodites. R. Yoshiyah says: The land was apportioned to those who left Egypt, as it is written "By the names of the tribes of their fathers shall they inherit." What, then, is the intent of "To these shall the land be apportioned"? (To such as these,) to exclude minors (below the age of twenty). R. Yonathan says: The land was apportioned according to those who came to the land, as it is written "To these shall the land be apportioned." And what is the intent of "By the names of the tribes of their fathers"? The L-rd changed this inheritance from all the inheritances in the Torah. For in all the inheritances in the Torah the living inherit the dead, whereas here, the dead inherit the living. Rebbi says: An analogy: Two brothers, Cohanim, were in a city. One had one son; the other, three. They go to the granary (to take their portion.) The first takes one sa'ah; the others, three, after which they go to their fathers' father and share equally. R. Shimon b. Elazar says: The land was apportioned to these and to these. How so? If they were of those who left Egypt, they took a share with those who left Egypt. If they were of those who entered the land, they took a share with those who entered the land. If they were both of these and of the others, they took a share of both — so that both verses are satisfied.
