Midrash su Levitico 17:2

1) (Vayikra 17:2) ("Speak to Aaron and to his sons and to all the children of Israel and say to them: This is the thing that the L–rd has commanded, saying:") This teaches us that the children of Israel are commanded not to slaughter and bring an offering outside (the Temple court), but not gentiles. And, what is more, a gentile is permitted to build a bamah (a temporary altar) in all places and to offer sacrifices to Heaven. If (it were written only) "the children of Israel," I would know (that this applies) only to the children of Israel. Whence do I derive (that it applies also) to proselytes and bondsmen? From "and say to them." I might thing that (only) Israelites, who are commanded against offering sacrifices within (viz. Bamidbar 18:4), are commanded against slaughtering outside; but Aaron and his sons, who are not commanded against offering sacrifices within, are not commanded against slaughtering outside. It is, therefore, written ("Speak to) Aaron and to his sons." Whence is it derived that the heads of tribes are included here? It is written here "This is the thing," and elsewhere (Bamidbar 30:1, in connection with vows,) "This is the thing." Just as there, the heads of tribes (are specified), here, too, the heads of tribes (are intended). And just as here, Aaron and his sons and the children of Israel (are specified), so, there, Aaron and his sons and the children of Israel (are intended — See Nedarim 78b).

2) "This is the thing that the L–rd has commanded": We are hereby taught that this section was stated (by Moses to Israel) word for word. This tells me only of this section alone. Whence do I derive that it applies to all of the sections? From "This is the thing that the L–rd has commanded" (i.e., He has commanded that it serve as an archetype (binyan av) for all of the sections.

(Lev. 17:3:) “If any single person from the House of Israel.” This text is related (to Ps. 51:20–21), “Make Zion prosper in Your good pleasure; rebuild the walls of Jerusalem. Then You shall delight in sacrifices of righteousness, burnt offerings, and whole offerings….” To what is the matter comparable? To a rich and noble man, who has no wife. His house was not [really] a house. Why? When the tenants came, he said to them, “Go rest in another place.” Why? Because he had neither house nor wife. He took a wife. He said to them, “Whatever you bring me, from now on bring them up to the house.” Thus all the days before Moses erected the tent of meeting, they offered sacrifices [in] any place, as stated (in Exod. 24:5), “Then he sent youths of the Children of Israel, and they offered burnt offerings….” And so it says (in Exod. 8:23), “Let us go a distance of three days into the wilderness and sacrifice to the Lord our God.” When the tabernacle was raised, the [Holy One, blessed be He,] said to Moses, “From now on you are only permitted to offer sacrifice in the tent of meeting”; and there they offered up the [gift]⁶⁷Gk.: doron. to the Holy One, blessed be He. It is so stated (in Deut. 12:13-14), “Take heed that you do not offer up your burnt offerings in any place that you see. But only in the place that the Lord will choose.” And where did the Holy One, blessed be He, choose? Jerusalem, as stated (in Ps. 132:13), “For the Lord has chosen Zion; He has desired it for His dwelling.” Moses therefore warns Israel, saying (in Lev. 17:3-4), “If any single person from the House of Israel [slaughters an ox, a lamb, or a goat in the camp]…. And does not bring it unto the entrance of the tent of meeting to offer it as a sacrifice… [bloodguilt shall be imputed to that person].“ The Holy One, blessed be He, foresaw that the Temple was going to be destroyed; so the Holy One, blessed be He, said, “As long as the Temple exists, you shall sacrifice within it, [and] there will be atonement for you; but when the Temple does not exist, how will there be atonement for you? Occupy yourselves with the words of Torah, because they are comparable with offerings, and they will atone for you.” Thus it is stated (ibid.), “This is the thing (literally: word).” So also the prophet says (in Hos. 14:3), “Take words with you, and return unto the Lord.” The words of Torah resemble all the offerings. One offers wine as a libation upon the altar, as stated (in Numb. 15:5), “And a quarter hin of wine for a libation”; and Torah resembles wine, as stated (in Prov. 9:5, where wisdom says), “and drink of the wine I have mixed.” One offers bread upon the altar, as stated (in Numb. 28:2), “My offering, My bread for My fire offering; and so it says (in Exod. 25:30), “And you shall set the [show]bread upon the table before Me always”; and Torah resembles bread, as stated (in Prov. 9:5, where wisdom says), “Come and eat of my bread.” One offers oil upon the altar, as stated (in Lev. 2:5), “fine flour mixed with oil”; and Torah resembles oil, as stated (in Eccl. 9:8), “Always let your clothes be white, and let there be no lack of oil upon your head.”⁶⁸Cf. Eccl. R. 9:8:1, which also understands this verse as referring to Torah.

[(Lev. 17:2:) THIS IS THE THING.] The Holy One foresaw that the Temple was going to be destroyed; so the Holy One said: As long as the Temple exists, you shall sacrifice within it, < and > there will be atonement for you; but when the Temple does not exist, how will there be atonement for you? Occupy yourselves with the words of Torah, because they are comparable with offerings, and they will atone for you. Thus it is stated (ibid.): THIS IS THE THING (literally:WORD). So also the prophet says (in Hos. 14:3 [2]): TAKE YOUR WORDS WITH YOU, < AND RETURN UNTO THE LORD…; LET US RENDER AS BULLOCKS THE OFFERING OF OUR LIPS >. The words of Torah resemble all the offerings. One offers wine as a libation upon the altar, as stated (in Numb. 15:5): AND A QUARTER HIN OF WINE FOR A LIBATION; and Torah resembles wine, as stated (in Prov. 9:5, where Wisdom says): AND DRINK OF THE WINE I HAVE MIXED. {And Torah resembles bread, as stated} [One offers bread upon the altar, as stated (in Numb. 28:2): MY OFFERING, MY BREAD FOR MY FIRE OFFERING; and so it says] (in Exod. 25:30): AND YOU SHALL SET THE [SHOW] BREAD UPON THE TABLE [BEFORE ME ALWAYS]; and Torah resembles bread, as stated (in Prov. 9:5, where Wisdom says): COME AND EAT OF MY BREAD. One offers oil upon the altar, as stated (in Lev. 2:5): FINE FLOUR MIXED WITH OIL; and Torah resembles oil, as stated (in Eccl. 9:8): ALWAYS LET YOUR CLOTHES BE WHITE, AND LET THERE BE NO LACK OF OIL UPON YOUR HEAD.⁸²Cf. Eccl. R. 9:8:1, which also understands this verse as referring to Torah.

Variantly: "If a man steal": Consecrated animals were also included in the general class, that if he stole them and slaughtered them outside (the azarah) he would pay "four and five." It is, therefore, written (Leviticus 17:2) "This is the thing that the L rd has commanded, etc." — They (consecrated animals slaughtered outside the azarah) have been singled out for kareth (cutting off, for the desecrator) and not for payment (of "four and five").
