Midrash su Levitico 18:7

9) (Vayikra 20:11) ("And a man who lies with his father's wife, he has revealed the nakedness of his father. Both of them shall be put to death; their blood is in them.") "And a man": to exclude a minor. "who lies with his father's wife": This implies both his father's wife who is his mother and his father's wife who is not his mother. Whence do we derive (for inclusion) his mother who is not his father's wife, (as when his father raped a woman, who gave birth to him)? From "he has revealed the nakedness of his father," which is superfluous for (purposes of) comparison and the derivation of an identity (gezeirah shavah [below]). "Both of them shall be put to death": by stoning. You say by stoning, but perhaps it is by one of the other death penalties in the Torah! It is, therefore, written "their blood is in them" and, elsewhere (Vayikra 20:27) "their blood is in them." Just as the penalty there is stoning; here, too, it is stoning. We have heard the punishment, but we have not heard the exhortation. It is, therefore, written (Vayikra 18:7) "The nakedness of your father and the nakedness of your mother you shall not reveal." "the nakedness of your father" — this is your father's wife. You say that it is your father's wife, but perhaps it is your father's nakedness, literally, (i.e., sodomy)! — You reason (otherwise), viz.: It is written here (Vayikra 18:7) "the nakedness of your father," and elsewhere (Vayikra 20:11) "he has revealed the nakedness of his father." Just as "the nakedness of his father there refers to the wife of your father, so "the nakedness of your father" here (Vayikra 18:7) refers to the wife of your father, and it implies both the wife of his father who is his mother and the wife of his father who is not his mother. Whence is derived (for inclusion) his mother who is not the wife of his father, (but a woman he ravished)? From (Vayikra 18:7) "the nakedness of your mother you shall not reveal." This tells me only of the exhortations. Whence are the punishments derived? You derive it by induction, viz.: It is written here (Vayikra 18:7) of the nakedness of his father, and it is written elsewhere (Vayikra 10:11) of the nakedness of his father. Just as in the latter instance, his mother who is not the wife of his father, (but a woman he ravished) is equated with his father's wife, in the former instance, too, she is equated with his father's wife, (and this is the "gezeirah shavah" referred to above). (Vayikra 18:7) "she is your mother": You make him liable for (only one sin-offering, by reason of her being) his mother, and you do not make him liable for (another sin-offering, by reason of her being) his father's wife.

14) (Vayikra 18:6) "A man, a man, to all the kin of his flesh shall not draw near to reveal nakedness" — general. (Vayikra 18:7) "The nakedness of your father and the nakedness of your mother you shall not reveal" — specific. General-specific (The rule is:) The general subsumes only the specific. (See Hermeneutical Principles 4) (And no arayoth are to be added (by induction) other than those which are specifically mentioned. For otherwise I would say:) Since he is permitted to marry the daughter of his father's brother and his father's brother is permitted to marry his daughter, then, if I have learned that he is forbidden to marry the wife of his father's brother, so, his father's brother should be forbidden to marry his wife. (A second instance:) Since he is permitted to marry the wife of his stepfather, and his stepfather is permitted to marry his wife, then, if I have learned that he is forbidden to marry the daughter of his stepfather, so, his stepfather should be forbidden to marry his daughter. If so, you have adduced arayoth by induction! — wherefore it is written "A man, a man, to all the kin of his flesh shall not draw near to reveal nakedness" — general. "The nakedness of your father and the nakedness of your mother you shall not reveal" — specific. General-specific. (The rule is:) The general subsumes only the specific. "I am the L–rd," the Judge, to exact punishment and trusted to reward.

(Bamidbar 18:1) "And the L-rd said to Aaron: You and your sons and the house of your father shall bear the sin of the sanctuary.": R. Yishmael says: Because the thing (i.e., what follows) is relegated to Aaron, it is he that is exhorted. R. Yoshiyah says: Whence is it derived that if he (a Cohein) sprinkled the blood without knowing in whose name he is doing so or smoked the fat without knowing in whose name he is doing so, that the Cohanim bear the sin for this? From "You and your sons and the house of your father shall bear the sin of the sanctuary." R. Yonathan says: Whence is it derived that if he took the flesh (of a sin-offering or a burnt-offering) before the blood was sprinkled (viz. Vayikra 7:7), or the breast and the shoulder before the smoking of the fats (viz. Ibid. 7:31), that the Cohanim bear the sin for this? From (Bamidbar, Ibid.) "And you and your sons with you shall bear the sin of your priesthood." And thus do we find that the decree of Eli was sealed only because they (the Cohanim) abused the offerings, as it is written (I Samuel 2:15) "Even before they would burn the fat … (16) And the man would say: Let them first burn the fat today (upon the altar) … (17) And the sin of the youths (the attendants of the Cohanim was very great, etc." And similarly we find that the decree of the men of Jerusalem was decreed only because they abused the offerings, viz. (Ezekiel 22:8) "You abused My offerings." (Bamidbar, Ibid.) "And you and your sons with you shall bear the sin of your priesthood.": This refers to a sin (in the area of) what is relegated to the Cohanim (i.e., to keep zarim [non-priests] from entering the sanctuary). You say this, but perhaps it refers to a sin (in the area of) what is relegated to beth-din, (it being their duty to exhort the Cohanim in this regard.) (This is not so, for [Ibid. 7]) "You and your sons, with you shall guard your priesthood for every thing of the altar" already speaks of what is relegated to beth-din. How, then, am I to understand "you shall bear the sin of your priesthood"? As referring to a sin (in the area of) what is relegated to the priesthood. (Ibid. 1) "And you and your sons with you": and not Israelites (i.e., they are not to guard the sanctuary.) You say that Israelites do not bear the sin of the Cohanim, but perhaps Levites, (who also guard the sanctuary) do bear the sin of the Cohanim, (who are remiss in this regard.) It is, therefore, written (Ibid. 23) "And they (the Levites) shall bear their (own) sin" (of remissness), but not the sin of the Cohanim. (Ibid. 2) "And also your brothers": I might think that this also includes Israelites. It is, therefore, written "the tribe of Levi." I might think that the women, too, are included. It is, therefore, written "your brothers" — to exclude the women. "draw near with you": R. Akiva says: It is written here "with you," and elsewhere, (Ibid. 7) "with you." Just as here, the Levites are being referred to, so, there, the Levites are being referred to — to exhort the Levites (against defect) in the song at their stand. (Ibid. 2) "and they shall be joined to you and they shall serve you": through their service. Treasurers and trustees are to be appointed from among them. You say this, but perhaps the intent is that they shall serve you (the Cohanim) in your (priestly) service. It is, therefore, (to negate this) written (Ibid. 3) "And they shall keep your charge and the charge of all the tent." — But perhaps (both are intended, i.e.,) they shall serve you in your (priestly) service and they shall serve you through their service. It is, therefore, written (Ibid. 6) "And I, behold, I have taken your brothers, the Levites, from the midst of the children of Israel, for you as a gift, given to the L-rd." To the L-rd are they given, and not to the Cohanim — whereby we derive that it is not to be construed in the second way (i.e., "for your [priestly] service"), but in the first way, i.e., their being appointed as treasurers and trustees. "and you and your sons with you, before the tent of Testimony": the Cohanim within, (in the court of the sanctuary,) and the Levites outside (the court). You say this, but perhaps the intent is both, within. It is, therefore, written (Ibid. 4) "And they (the Levites) will join you, and they will keep (the watch of) the watch (by the Cohanim within) of the tent of meeting." How, then, am I to understand "and you and your sons with you, before the tent of Testimony"? The Cohanim within, and the Levites outside. (Ibid. 3) "And they shall keep your charge and the charge of all the tent": As stated above: They will serve you through their service, and appoint from among them treasurers and trustees. "But to the vessels of the kodesh they shall not come near." This "hakodesh" ("the holy") refers to the ark, as it is written (Ibid. 4:20) "And they (the Levites) shall not come to see (the vessels) when the kodesh is being covered and they (the Levites) die." "and to the altar": This refers to the (sacrificial) service of the altar. "they shall not come near": the exhortation. "and they shall not die": the punishment. This tells me only of the Levites, that they are punished and exhorted for (appropriating) the service of the Cohanim. Whence do I derive (the same for) Cohanim (appropriating) the service (i.e., singing) of the Levites? From ("so that they not die,) both they (the Levites) and you" (the Cohanim.) And it once happened that R. Yehoshua b. Chanania sought to assist R. Yochanan b. Gogada, when he (R. Yehoshua) said to him: Get back, for you are close to forfeiting your life! For I am of the gatekeepers and you are of the singers. Rebbi says that this ("both they and you") is not needed (for the above learning). For it is already written (Bamidbar 4:18-19) "Do not cut off the tribe of the families of the Kehathi … but do this for them and they will live," (the implication being that otherwise they will die.) This tells me only of the sons of Kehath. Whence do I derive (the same for) the sons of Gershon and the sons of Merari? From (Ibid. 19) "Aaron and his sons shall come and set them (the sons of Levi), each man to his service and to his burden." This tells me only that the Levites are punished for (appropriating) the service of the Cohanim. Whence do I derive (the same for) the Cohanim (appropriating) the service of the Levites? From (Bamidbar 1:51) "And when the mishkan travels, the Levites (and not the Cohanim) shall dismantle it. And the stranger (a non-Levite) that draws near (to this service) shall be put to death." Whence do I derive (the same for) one who goes from his (assigned) service to another? From (Ibid. 3:38) "And those who encamped before the mishkan, in front, before the tent of meeting on the east" (i.e., only these being assigned to the aforementioned service) … and the stranger (to that service, [even a Levite]) that draws near shall be put to death." What, then, is the need for "so that they not die both they and you"? Because Korach came and contested Aaron's prerogative, Scripture reiterated the entire exhortation (on demarcation of bounds). Variantly: "both they and you": Just as you (the Cohanim, are thus forewarned) vis-à-vis the altar service, so, they (the Levites, are thus forewarned). R. Nathan says: Levitical singing is hereby intimated in the Torah, but it (i.e., its nature) was explicated by Ezra. Chanania, the son of the brother of R. Yehoshua says: This (intimation) is not needed, for it is already written (Shemot 19:19) "and G-d answered him (Moses, the Levite) by voice" — relative to the mitzvah of the voice, whence (the mitzvah of Levitical) singing is intimated in the Torah. (Bamidbar 18:4) "And they shall join you": As we have stated, the Cohanim (keep guard) on the inside, and the Levites, on the outside. (Ibid.) "and a stranger shall not draw near to you": Why is this written? (i.e., it has already been mentioned.) — "and the stranger that draws near shall be put to death" tells us (only of) the punishment. Whence do we derive the exhortation? From "and a stranger shall not draw near to you." (Ibid. 5) "And you shall keep the charge of the sanctuary and the charge of the altar.": This is an exhortation to a beth-din of Israelites to exhort the Cohanim towards the proper performance of the (sacrificial) service, which (service), when properly performed, fends off calamity from the world. (Ibid.) "so that there be no more wrath." Why "no more"? For He has already vented His wrath (viz. 17:11). Similarly, (Bereshit 9:11) "and no more shall there be a flood." Why "no more"? For it has already happened. Similarly, (Vayikra 18:7) "And they shall no more offer their sacrifices to the goat-demons." Why "no more"? Because it already happened (in Egypt, viz. Ezekiel 20:7). Similarly, (Bamidbar 18:22) "And the children of Israel shall no more draw near to the tent of meeting." Why "no more"? Because they had already done so (in the time of Korach, viz. Ibid. 16:35). Here, too, (Ibid. 18:5) "so that there be no more wrath." Why "no more"? For He had already vented His wrath, as it is written (Ibid. 17:11) "for the wrath has gone forth, etc."
