As explained in Halachah 3.
I.e., to offer incense, kindle the Menorah, or to bow.
According to its simple meaning, the prooftext cited below refers only to Aaron. Nevertheless, through the Biblical exegesis, the Sifra interprets it as referring to all priests (Kessef Mishneh).
Sefer HaMitzvot (negative commandment 68) and Sefer HaChinuch (mitzvah 184) include this commandment among the 613 mitzvot of the Torah. In Sefer HaMitzvot, the Rambam explains that this mitzvah is an expression of honor and reverence toward the Temple.
The Kessef Mishneh questions the Rambam’s interpretation of the verse, for seemingly, “within the curtain” refers to the Holy of Holies. On the surface, the opposite would be more appropriate: “The Holy Chamber” could be interpreted as referring to the entire Temple and “within the curtain” to the Holy of Holies. He explains the verse as follows: Were the verse to have mentioned “the Holy Chamber” alone, we would have thought that it refers only to the Holy of Holies and not to the Temple at large. Since, however, the verse adds “within the curtain,” we understand that it refers to the Holy of Holies” and “the Holy Chamber” refers to the entire Sanctuary.
There is, however, a difference in the punishments for which one is liable for the violation of the two aspects of this commandment, as the Rambam states in Halachah 4.
Hilchot Avodat Yom HaKippurim, ch. 4.
With regard to the priests’ prostrating themselves, see Hilchot K’lei HaMikdash 5:11. The Kessef Mishneh explains that the priests were not allowed to enter the Sanctuary to prostrate themselves at all times. Instead, they would enter only at a specific time, when the service of the morning was completed.
Sefer HaMitzvot (negative commandment 165) and Sefer HaChinuch (mitzvah 151) include this commandment among the 613 mitzvot of the Torah.
If, however, he is not involved in the Temple service, he is not required to remain in the Temple.
The Ra’avad differs with the Rambam, maintaining that the prooftext the Rambam cites was directed to Aaron’s sons and applied only at the time of the death of Nadav and Avihu at the dedication of the Sanctuary. In other instances, there is no prohibition for an ordinary priest to leave the Temple. The prohibition applies to the High Priest alone. The Kessef Mishneh refers to the Sifra which as interpreted by the Ramban - serves as support for the Rambam’s ruling.
The Ra’avad amplifies his difference of opinion with the Rambam, maintaining that the ordinary priest should certainly leave the Temple to participate in the funeral of a close relative. Indeed, he is forced to become impure to take part in the burial. Moreover, since he cannot complete the service, what value is there in him remaining?
The Kessef Mishneh justifies the Rambam’s ruling, explaining that were he to depart from the Temple, it would be demeaning to the service that he had performed. The implication would be that it was not of serious importance to him. Also, there is a practical dimension; if he would depart, there might not be anyone to see that the service is in fact completed.
See Halachah 9 for a definition of this term. See also Hilchot Eve [4:6, 9, for particulars with regard to the state of aninut, acute mourning.
The Rambam’s statements are taken from Zevachim 17b. The Talmud there offers another derivation. Significantly, in his Sefer HaMitzvot, loc. cit., the Rambam uses that derivation and not the one mentioned here.
See Chapter 6, Halachah 12.
See Hilchot Ma’aseh HaKorbanot 10:17.
See Hilchot Ma’aser Sheni 3:7.
Aaron asked this rhetorical question to Moses after serving in the Sanctuary, but not partaking of the offerings, on the day his sons died.
As explained in Hilchot She’ar Avot Hatum’ah 12:15, since a person who was in a state of acute mourning was forbidden to partake of holy objects, it is possible that he diverted his attention from his hands and touched a source of impurity unknowingly. Nevertheless, this is only a safeguard and applies only with regard to partaking of food and not to touching it.
A person's mother, father, son, daughter, brother, and sister. One must mourn for his or her spouse according to Rabbinic Law (Hilchot Evel 2:1).
I.e., the person died beforehand and the priest heard the report within 30 days of his death. In that instance, he is required to observe a full week of shivah mourning (Hilchot Evel 7:1).
I.e., unearths his grave for the sake of reburying him in another place.
Hilchot Korban Pesach 6:9. There it is explained that our Sages did not wish to enforce their decree in a situation that would lead to the violation of a transgression punishable by karet.
See Mo’ed Kattan 16b which states that this is derived from the term shelamim (“peace-offerings”). That name implies that these offerings may only be brought when a person is at peace with himself.
A physical ailment similar to leprosy which causes one to become ritually impure.
I.e., the Temple Mount; see Chapter 3, Halachah 2, which explains these concepts.
See Hilchot Talmud Torah, ch. 7, for a definition of this term.
Mo’ed Kattan 15b explains this question as follows: During the 40 years between the sin of the spies and the entry of the Jews into Eretz Yisrael, they were considered as if they were under a ban of ostracism from God. Nevertheless, their sacrifices were offered. Hence one might conclude that even though a person is under a ban of ostracism, his sacrifices may be offered. That conclusion is not accepted unquestioningly, however, because it is possible to make a distinction between one who is ostracized by God (as the Jews were in the desert) and one ostracized by man. It is possible that the latter situation is more severe.
They may not, however, enter the Temple themselves to take part in the offering.
The Kessef Mishneh raises a question for it is necessary to perform semichah (leaning on the sacrificial animal with all one’s strength; see Hilchot Ma’aseh HaKorbanot, ch. 3) on sacrifices. Since these individuals may not enter the Temple Courtyard, because of their impurity, they cannot perform semichah. Hence, seemingly, the sacrifices should not be offered. The Kessef Mishneh states that perhaps the Rambam is speaking only of certain sacrifices where semichah is not required.
Unless he has already immersed himself. See Hilchot Korban Pesach 6:1.
For as explained in Hilchot Korban Pesach 2:3, 5-6, the Paschal sacrifice should be sacrificed only on behalf of individuals who are fit to partake of it and a person who is ritually impure and an uncircumcised person are forbidden to do so.
I.e., he must have the ashes of the red heifer sprinkled upon him, and he must immerse in the mikveh.
