It is a positive commandment for a priest¹ (positive commandment 24) which state "A priest alone is obligated...," i.e., a priest and not a non-priest. who serves [in the Temple] to sanctify his hands and feet² and afterwards perform service,³ (ibid.) and Sefer HaChinuch (mitzvah 106) consider this as one of the 613 mitzvot of the Torah. as [Exodus 30:19] states: "And Aaron and his sons will wash their hands and their feet from it." A priest who serves⁴ without having sanctified his hands and feet in the morning⁵ is liable for death at the hand of heaven,⁶ 19:3, he is not liable for lashes, because he has only violated a positive commandment, not a negative commandment. as [ibid.:20] states: "They shall wash with water and not die." Their service - whether that of a High Priest or an ordinary priest - is invalid.

footnotes: ¹ The Rambam emphasizes that this mitzvah applies to a priest, because an animal offered as a sacrifice may be slaughtered by a non-priest. Such a person need not sanctify his hands and feet. This explanation is reinforced by some of the versions of Sefer HaMitzvot ² Through washing them from the basin in the Temple Courtyard, as the Rambam proceeds to explain. ³ Sefer HaMitzvot ⁴ If he does not perform service in the Temple Courtyard, he is not liable even if he enters without sanctifying his hands and feet (Rav Yosef Corcus). ⁵ With the latter addition, the Rambam excludes the extra sanctifications performed by the High Priest on Yom Kippur before and after the changes of his garments. If he does not sanctify his hands and feet at this time, he does not invalidate his service, as stated in Halachah 7. ⁶ Nevertheless, as explained in Hilchot Sanhedrin

Which source teaches that his service is invalid? [Ibid.:21] states: "It will be an eternal statute for him and his generations," and with regard to the Priestly garments [ibid. 25:43] also uses the expression: "An eternal statute."⁷ does not quote the verse exactly. Just as [a priest] who is lacking the priestly garments invalidates his service, as we explained,⁸ 10:4. so, too, one who did not wash his hands invalidates his service.

footnotes: ⁷ The text of the Mishneh Torah ⁸ Hilchot K'lei HaMikdash

A priest does not have to sanctify [himself] between every service [that he performs]. Instead, he consecrates [his hands and feet] once in the morning and may continue serving throughout the day and [the subsequent] night,⁹ provided he does not: a) depart from the Temple;¹⁰ b) sleep;¹¹ explains that this requirement is derived from the obligation to sanctify one's hands and feet if one diverts attention, for it is likely that while sleeping, one did divert his attention. c) urinate;¹² or divert his attention [from his hands and feet]. If he does any of the above, he must sanctify his hands and feet again.

footnotes: ⁹ On the following day, he must sanctify his hands and feet again, even if he did not sleep at night, as stated in Halachah 8. ¹⁰ See Halachah 5. ¹¹ The Kessef Mishneh ¹² See Halachah 5 with regard to defecation.

If a priest departed from the Temple, returned and then performed service without sanctifying [his hands and feet], his service is acceptable¹³ 20b. Hence, the Rambam rules leniently (Kessef Mishneh). if he did not divert his attention.¹⁴). This general principle was followed in the Temple: No person would enter the Temple Courtyard to perform service¹⁵ unless he immersed [in the mikveh] even though he was ritually pure.

footnotes: ¹³ There is an unresolved question concerning this point in Zevachim ¹⁴ In the other three instances mentioned above, if he serves without sanctifying his hands and feet, his service is invalid (Kessef Mishneh ¹⁵ There is a difference of opinion among the commentaries if a ritually pure person who enters the Temple Courtyard without intending to perform service is obligated to immerse himself or not.

Anyone who defecates must immerse himself [in a mikveh].¹⁶ Anyone who urinates must sanctify his hands and feet. [The following rules apply when] one goes outside the walls of the Temple Courtyard. If he departed [with the intent of] staying outside for an extended time, he must immerse [in a mikveh].¹⁷ If [his intent] was to return immediately, when he returns, all that is necessary is that he sanctify his hands and feet. If he did not immerse, nor sanctified his hands and feet and carried out [sacrificial] service, his service is acceptable¹⁸ 20b. Hence, the Rambam rules leniently (Kessef Mishneh). since he did not divert his attention, nor did he defecate or urinate. If he merely placed his hands outside the Temple Courtyard, he is not required to sanctify them again.

footnotes: ¹⁶ See the conclusion of Halachah 6. ¹⁷ Even if he actually remained outside for a short time. ¹⁸ There is an unresolved question concerning this point in Zevachim

If [only] a person's hands become ritually impure,¹⁹, ch. 8. he may immerse them and they are ritually pure. He need not sanctify them again. If his body became impure because he partook of impure foods or drank impure beverages and immersed himself, even though he does not have to wait until nightfall [to become ritually pure],²⁰ 9:9. he must sanctify [his hands and feet] after immersing himself, for everyone who immerses himself must sanctify his hands and feet [before] serving. If he did not sanctify [his hands and feet], his service is not desecrated since he did not divert his attention.

footnotes: ¹⁹ This refers, not to ritual impurity prescribed by Scriptural Law, but instead, to certain states of ritual impurity ordained by our Sages that affect the hands alone. See Hilchot Sha'ar Avot HaTumah ²⁰ See Hilchot Sha'ar Avot HaTumah

When a High Priest does not immerse himself nor sanctify his hands and feet between his changes of clothes and between his different services on Yom Kippur²¹ 2:2 for a description of these changes of clothing, immersions, and sanctifications. and [continues] serving, his service is acceptable.²² 30b). [The rationale is that] since those immersions and sanctifications are not applicable equally to Aaron and his sons,²³ as [Exodus 30:19] states: "And Aaron and his sons will wash from it." Only an obligation that is equally applicable to all the priests is an indispensable obligation, i.e., the first sanctification of one's hands.

footnotes: ²¹ See Hilchot Avodat Yom HaKippurim ²² He does, however, violate a positive commandment, because he does not perform the Yom Kippur service as prescribed (Yoma ²³ They are obligations of the High Priest (Aaron), but not an ordinary priest (his sons).

If a person sanctified his hands on one day, he must sanctify them again on the following day even though he did not sleep at all that night, for the hands are disqualified because of the passage of the night. [Even] if he sanctified his hands at night and offered fats on [the altar's pyre] the entire night,²⁴ he must go back and sanctify [his hands] on the next day²⁵ for that day's service.

footnotes: ²⁴ I.e., he was continually involved in the Temple service. ²⁵ At daybreak.

If a priest sanctified his hands and his feet for the removal of the altar's ashes,²⁶ 2:11-12). even though he sanctifies them before sunrise,²⁷ he does not have to sanctify them again after daybreak, because he sanctified them at the beginning of the day's service.

footnotes: ²⁶ Which is carried out at dawn (Hilchot Temidim UMusafim ²⁷ Halachically, depending on the different opinions, dawn is between 72 minutes and two hours before sunrise. Sunrise is the time when the priest should sanctify his hands. Nevertheless, in this instance, he has no alternative, since he is sanctifying them for that day's service and that service is performed before dawn.

It is a mitzvah to sanctify [one's hands and feet] from the basin.²⁸. If, however, one sanctifies them from a sacred utensil, the sanctification is effective. Sanctification may not, however, be performed with an ordinary utensil.²⁹ If one sanctified [his hands and feet] with a sacred utensil outside the Temple³⁰ 22a). or did so with an ordinary utensil within the Temple and then performed service, his service is disqualified. One does not sanctify his hands and feet inside the basin or a sacred utensil, but from them, as [implied by the verse]: "Aaron and his son's will wash from it;" ["from it"] and not "inside of it." If one sanctified [his hands and feet] in such a utensil and performed service, he did not desecrate it.

footnotes: ²⁸ See the description of this utensil in the conclusion of ch. 4 of Hilchot Beit HaBechirah ²⁹ I.e., one that is not consecrated. ³⁰ The sanctification must be performed within the Temple Courtyard, for that is where the basin is located. Even though the sanctification need not be performed with water from the basin, it must be performed in the area where it is located (Zevachim

If one immerses his hands and feet in the waters of a mikveh³¹ on the Temple Mount. or even a spring, this is not considered as sanctification. One must wash them from a utensil. One may sanctify them using any sacred utensil whether or not it contains a revi'it.³²; 150 cc. according to Chazon Ish. The Ra'avad states - and the Kessef Mishneh explains that this is also the Rambam's intent - that if one uses a small utensil, he must take the water originally from the basin.

footnotes: ³¹ There were several mikvaot ³² 86 cc. according to Shiurei Torah

All water is acceptable for the sanctification, whether water from a spring or water from a mikveh, provided its appearance has not changed and it is [thus] acceptable for immersion.³³ 7:1, if the appearance of water has changed, e.g., one poured wine or juice into it and changed its color, it is not acceptable for immersion. Mud that can be poured, from which a cow would drink,³⁴ 7:3, 8:9. 11:2. can be used to fill the measure of the basin. This is the general rule: Any water that can be used to make up the measure of a mikveh can be used to make up the measure of the basin.³⁵ must be 40 se'ah in volume.

footnotes: ³³ As stated in Hilchot Mikvaot ³⁴ Since a cow will drink it, it is considered as water and not as earth. Compare to ibid. ³⁵ A mikveh

How much water must there be in the basin? At least enough for four priests to sanctify [their hands and feet] from it, as [indicated by Exodus 30:19 which] mentions "Aaron and his sons." Together with him, there were Elazar, Itamar, and Pinchas, a total of four.³⁶ 21b cites Exodus 40:32 which states "And Moses, Aaron, and his sons will wash from it." "His sons" is plural indicating at least two, thus reaching a total of four. The Rambam, here and in his Commentary to the Mishnah (Zevachim 2) substitutes Pinchas for Moses. The Kessef Mishneh questions that explanation on two counts: Firstly, at the time, the basin was first used, Aaron's older sons, Nadav and Avihu, were still alive. Moreover, the priesthood had not been granted to Pinchas as of yet. Rav Yosef Corcus tries to support the Rambam's understanding, explaining that according to certain views, Moses did not serve as a priest when Aaron did, only in the seven days of preparation.

footnotes: ³⁶ Zevachim

The water in the basin is disqualified if left [in it] overnight, as we explained.³⁷ 3:18. What would be done [to prevent the water from being disqualified]? The basin would be submerged in a mikveh³⁸ 1:4), the Rambam explains that each night the basin would be submerged in a muchani, a large container which held a reservoir of water. This container was not a sacred utensil and hence the water it contained was not disqualified overnight. See Hilchot Beit HaBechirah, loc. cit., for a description of this container. or a spring and on the following day, it would be raised or it would be filled each day in the morning.

footnotes: ³⁷ Hilchot Beit HaBechirah ³⁸ In his Commentary to the Mishnah (Tamid

The "sea" fashioned by Solomon³⁹ had the status of a mikveh,⁴⁰. because a channel of water from the Spring of Aitem⁴¹ would pass through it.⁴² 3:8)]. Therefore,⁴³ its waters were not disqualified with the passage of night like the water of the basin and [indeed,] the basin was filled from it.

footnotes: ³⁹ See I Kings 7:23-26. This was a circular copper tank, ten cubits in diameter and five cubits deep. ⁴⁰ As II Chronicles 4:6 states, the priests would use it as a mikveh ⁴¹ A mountain spring slightly south of Jerusalem. It was 32 cubits higher than the Temple Mount. Hence the water would naturally flow through a conduit built from it to the Temple. ⁴² Usually, water contained in a utensil is not acceptable for immersion. Nevertheless, since water from a flowing spring passed through this tank, its water was acceptable [the Jerusalem Talmud (Yoma ⁴³ I.e., because it was connected to a flowing spring.

How is the mitzvah of sanctification performed? [A priest would] put his right hand on his right foot and his left hand on his left foot and bend over and sanctify them.⁴⁴ 15:5 which states that one would wash until the wrist. All the substances that are considered as intervening with regard to immersion,⁴⁵, ch. 2, no significant substance may intervene between the flesh of the person immersing and the waters of the mikveh. That chapter details those substances that are considered as significant and hence, as intervening, and those which are not. are intervening with regard to the sanctification of hands. One may not sanctify his hands while sitting, because [the sanctification] is comparable to the Temple service and the Temple service may be performed only when standing, as [Deuteronomy 18:5] states: "To stand and to serve."⁴⁶), he offers another rationale: that one is not allowed to sit in the Temple.

footnotes: ⁴⁴ I.e., a colleague would pour water over them; alternatively, he would stand under a tap.See Hilchot Nesiat Kapayim ⁴⁵ As explained in Hilchot Mikvaot ⁴⁶ In the Rambam's Commentary to the Mishnah (Zevachim, loc. cit.

Anyone who performs service while he is seated, desecrates his service and disqualifies it. He does not receive lashes, because the warning against doing so stems from a positive commandment.⁴⁷ Similarly, anyone involved with one of the Temple services must be standing on the floor.⁴⁸ 24a relates that since both the Temple utensils and the ground of the Temple Courtyard have been sanctified, an equation is established between them. Just as there can be no intervening substance between a priest's hand and a sacred utensil, so too, there may be no intervening substance between his feet and the Temple Courtyard. If there was anything intervening between himself and the ground,⁴⁹ e.g., he was standing on a utensil, an animal, or a colleague's foot, [his service] is invalid. Similarly, if there was anything intervening between his hand and the utensil with which he was performing the service, it is invalid.⁵⁰).

footnotes: ⁴⁷ And lashes are given only when a negative commandment is violated. ⁴⁸ Zevachim ⁴⁹ I.e., the stones of the Temple or the Temple Courtyard. ⁵⁰ This is derived from Leviticus 4:5: "And the priest shall take." Implied is that the taking must be performed by the priest's body without any intermediary (Zevachim, loc. cit.

The Temple service may be performed only with one's right hand.⁵¹), the Rambam writes that "Whenever the word "hand" is mentioned [with regard to the Temple service], the intent is the right hand." The above is referring to a right-handed person. A left-handed priest is disqualified from serving in the Temple, as stated in Chapter 8, Halachah 11. If one performed service with his left hand, it is invalid. He is not liable for lashes.⁵²). [The following laws apply when] one of [a priest's] feet are on a utensil and one is on the floor, one is on a stone [that was not embedded in the floor] and one was on the floor. We evaluate [the situation]. Whenever he would be able to stand on his one foot if the utensil or the stone were taken away, his service is acceptable.⁵³ If not, his service is invalid.⁵⁴ If he received [blood from a sacrifice] with his right hand and his left hand is supporting it, his service is acceptable, because we do not pay attention to [something that is] a [mere] support.⁵⁵ 93b).

footnotes: ⁵¹ Indeed, in his Commentary to the Mishnah (loc. cit. ⁵² For there is no explicit prohibition that he violates. Instead, it is an extension of a positive commandment (Kessef Mishneh ⁵³ For then, the support provided by the second foot is not of consequence. ⁵⁴ For then it is significant. ⁵⁵ This is a general principle, applying in other situations as well (see Shabbat

When one of the stones of the Temple Courtyard has become loosened, one should not stand upon it during one's Temple service until it is affixed in the ground.⁵⁶ If he performed service, his service is acceptable,⁵⁷ 24a. Hence, the Rambam does not rule stringently. See also the commentaries to Hilchot Beit HaBechirah 1:10. since it is located in its place.

footnotes: ⁵⁶ As long as it is not fixed in the ground, the stone can be considered as a separate entity and therefore, it could be considered as an intervening substance between the priest and the earth. ⁵⁷ There is an unresolved question concerning this issue in Zevachim
