Twenty-four priestly gifts were given to Aharon and his sons, in particular, in general and with an everlasting covenant. These are they: ten in the Temple, four in Jerusalem and ten in the surrounding environs. Ten in the Temple: sin offering, guilt offering, communal peace offerings, bird sin offerings, conditional guilt offerings, the oil of the leper's offering, the two loaves of Shavuot, the weekly showbread, the remains of the flour offerings and the Omer offering. Four in Jerusalem: first born animals, first fruits, the elevated portions of the thanksgiving and Nazirite offerings, and the skins of the sacred offerings. Ten in the surrounding environs: the terumah portion of produce, the terumah taken from the Levitical tithe, the first bread (challah), the first fleece, the shoulder, cheek and stomach portion, redemption of the first born male child, redemption of the first born donkey, devoted offerings, a devoted ancestral field which was not redeemed, returned property stolen from a convert who is dead. All of these were give to Aharon and his sons in general, in particular and with an everlasting covenant in order to create an obligation on the whole and on each particular, to grant a reward on the whole and on each particular. One who transgresses and withholds them is as if they transgressed both on the whole and the particular.

"[Be betrothed to me] with the understanding that if I die you will not bound to a levir"—she is betrothed but his stipulation is invalid, for he stipulated against what was written in the Torah, and anyone who stipulates against what is written in the Torah, his stipulation is invalid. "With the understanding that I will have no responsibility for you for clothing or sex"—she is betrothed but his stipulation is invalid. This is the pneumonic: Anyone who stipulates against what is written in the Torah regarding a monetary matter—his stipulation stands; with a non-monetary matter—his stipulation is invalid.

(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.
