There is a positive commandment to offer all of the sacrifices - whether sacrifices of animals or fowl or meal-offerings - in [God's] chosen house,1Sefer HaMitzvot (positive commandment 84) and Sefer HaChinuch (mitzvah 440) include this commandment as one of the Torah's 613 mitzvot. as [Deuteronomy 12:14] states: "There you will perform everything that I command you." Similarly, it is a positive commandment for a person to take the effort to bring animal sacrifices2The Kessef Mishneh explains that this excludes sacrifices from fowl, but this understanding is not accepted by all authorities. that he is obligated to bring3Temurah 21a states that the firstborn offering is not included in this commandment. [and transport them] from the Diaspora to [God's] chosen house,4Sefer HaMitzvot (positive commandment 85) and Sefer HaChinuch (mitzvah 453) include this commandment as one of the Torah's 613 mitzvot. The Ramban differs and maintains that this should not be considered as an independent mitzvah. as [ibid.:26] states: "[Only] your sacraments that you possess and your vows shall you bear... [to the place that God will choose]." According to the Oral Tradition, we have learned that [the verse] is speaking only about sacrificial animals from the Diaspora which he takes the effort to deal with until he brings them to [God's] chosen house.

One who offers a sacrifice outside the Temple Courtyard negates a positive commandment5The one stated in the previous halachah. and violates a negative commandment,6Sefer HaMitzvot (negative commandment 90) and Sefer HaChinuch (mitzvah 186) include this prohibition as one of the Torah's 613 mitzvot. There are several historical dimensions to this prohibition. First of all, in the era between the destruction of the Sanctuary of Shiloh and the construction of the Temple, it was permitted to offer sacrifices on bemot (literally, "high-places"), i.e., individual altars. See the notes to Hilchot Beit HaBechirah 1:3 which explain the transition between these periods. It is also relevant with regard to the sanctuary constructed by Chonio, the son of Shimon the Just, described in the notes to Hilchot Bi'at HaMikdash 9:14. as [ibid. :13] states: "Take heed lest you offer your burnt-offerings in any place that you see." If he offered a sacrifice [in such a place] willfully, he is liable for karet,7Literally, the soul's being cut off. This involves premature death in this world (before the age of 50, Mo'ed Kattan 28a) and the soul not meriting a portion in the world to come (Hilchot Teshuvah 8:1). as [Leviticus 17:8-9] states: "[Any man]...who will offer a burnt-offering or a sacrifice, but did not bring it to the Tent of Meeting... he will be cut off from his people." [If he transgressed] unknowingly, he must bring a fixed8This term is used to distinguish this sacrifice from the adjustable guilt offering. See Hilchot Shegagot 1:4. sin-offering.

Similarly, one who slaughters sacrificial animals outside [the Temple Courtyard], even though he does not offer them as a sacrifice, [is liable].9Sefer HaMitzvot (negative commandment 89) and Sefer HaChinuch (mitzvah 439) include this prohibition as one of the Torah's 613 mitzvot. If he acted willfully, he is liable for karet, as [ibid:3-4]: "[Any man]...who will slaughter an ox, a sheep, or a goat... it will be considered as [the shedding of] blood for that person. He has shed blood... He will be cut off." [If he transgressed] unknowingly, he must bring a fixed sin-offering.

Which source serves as a warning not to sacrifice outside [the Temple Courtyard]? [It is derived through] an association of verses. [Deuteronomy 12:14] states: "There will you offer your burnt-offerings" and it continues: "There you will perform everything that I command you." [We can conclude:] Just as [the Torah] warns explicitly against offering a sacrifice outside the Temple, and one incurs punishment for this, as it is written: "Take heed lest you offer your burnt-offerings...," so too, it has warned with regard to the "performance" that is involved in slaughtering, for which it is explicitly stated that one receives punishment. For the Torah does not prescribe punishment unless it has issued a warning.

A person who slaughters sacrificial animals outside [the Temple Courtyard] and offers them [in such a place] is liable twice: once for slaughtering and once for offering.10This applies even if he performed both transgressions without realizing the prohibitions involved in the interim, for they are two separate transgressions that are not dependent on each other (Radbaz).
If he slaughtered [a sacrificial animal] in the Temple Courtyard and offered it outside, he is liable for offering it. If he slaughtered [such an animal] outside, but offered it inside, he is liable for slaughtering it.

He is not liable unless he slaughtered sacrificial animals that are fit to be offered on the altar. If, however, he slaughtered an animal that was forbidden [to be offered on] the altar11I.e., the animals mentioned in Hilchot Issurei Mizbeiach. or one of the sin-offerings that was consigned to death12See Hilchot Pesulei HaMukdashim 4:1 for a definition of this term. outside [the Temple Courtyard], he is exempt.13It is, however, forbidden to do so. [The rationale is that Leviticus 17:414The source for this prohibition, as stated in Halachah 3.] mentions "before the Sanctuary of God." Whenever [an animal] is not fit to be come to the Sanctuary of God, one is not liable [for its slaughter].

If one slaughters an animal that is unacceptable because of a time factor involving its body15See the following halachah. or the status of its owners16See Halachah 9. outside the Temple Courtyard], he is exempt.17It is, however, forbidden to do so. [The rationale is that] in its present state, it is not fit to be brought into the Temple Courtyard.18The prohibition involves slaughtering sacrificial animals and since these animals are not fit to be sacrificed or their owners are not fit to sacrifice them, they are not considered sacrificial animals in the full sense.

What is meant by a disqualifying time factor involving its body? An animal in the seven days following its birth,19See Hilchot Issurei Mizbeiach 3:8 which states that it is a positive commandment to offer sacrificial animals after eight days of life, but not before. turtle-doves which have not reached the stage of development at which time [they are fit to be sacrificed],20See ibid.:2 which states that "Turtledoves are acceptable when [their feathers all] are of a golden hue." Before this stage, they are not acceptable (ibid.:9). and an animal and its offspring; for if one slaughters one on a particular day, the other is not fit to be slaughtered until the morrow.21See Hilchot Shechitah 12:1-2 which states that it is forbidden to sacrifice an animal and its offspring on the same day. No matter which is slaughtered first, one must wait until the following day to sacrifice the other.

What is meant by a disqualifying time factor involving the status of its owners? A sacrifice whose owners have not reached the appropriate stage of time to offer it.
What is implied? If a zav,22A person with a physical affliction somewhat similar to gonorrhea that renders one ritually impure and obligates him to bring a set of sacrifices (see Hilchot Mechusrei Kapparah 1:1, 3-4; 2:1). a zavah,23A woman who bleeds for three consecutive days after the seven days associated with her menstrual period. This renders her ritually impure and obligates her to bring a set of sacrifices (see ibid. 1:1, 3-4,6) and a woman who gave birth24Who is ritually impure after giving birth and must bring a set of sacrifices (see ibid. 1:1, 3, 5). slaughtered [the animal designated for] their sin-offerings outside [the Temple Courtyard] during the days of their counting,25As explained in the above sources, a zav and a zavah must wait seven "spotless days" after their condition ceases before bringing their sacrifices. A woman must wait 40 days after giving birth to a male and 80 days after giving birth to a female before bringing her sacrifices. they are exempt. Similarly, if a person afflicted with tzara'at26A skin affliction similar to, but not identical with leprosy that is a spiritual manifestation of the impurity resulting from improper speech (the conclusion of Hilchot Tuma'at Tzara'at). Such a person must bring a set of sacrifices when emerging from ritual impurity (see Hilchot Mechusrei Kapparah 1:1, 3-4). slaughtered his sin-offering and[/or] his guilt-offering outside [the Temple Courtyard] during the days of his counting,27Such a person must also wait seven days after his condition ceases before bringing his sacrifices. he is exempt, for the owners of these sacrifices are not yet fit for their atonement. Nevertheless, if these individuals slaughtered their burnt-offerings28The sacrifices of all of these individuals include a burnt-offering and a sin-offering and the sacrifice of a person emerging from tzara'at also includes a guilt-offring. outside [the Temple Courtyard] during the days of their counting, they are liable. [The rationale is that] a burnt-offering is a present29To appease God and restore His favor. and it is the sin-offering and the guilt-offering which are the fundamental [factors leading to] atonement.
Similarly, when a nazirite slaughters his sin-offering outside [the Temple Courtyard] during the days of his nazirite vow, he is exempt.30See Hilchot Nezirut, ch. 8, for the details regarding the sacrifices a nazirite must bring upon completion of his nazirite vow. He may not bring these sacrifices beforehand. If he offered his burnt-offering or his peace-offering outside [the Temple Courtyard], he is liable. For the sin-offering is what prevents him [from completing his nazirite vow] and it is the fundamental dimension [of the conclusion of] his nazirite vow.

When a person offers a conditional guilt-offering31See Hilchot Shegagot, Chapter 8, for a description of the situations which warrant bringing these sacrifices. or sin-offering of fowl that is brought because of a doubt32See Hilchot Mechusrei Kapparah 1:7 which describes the situations under which such sacrifices should be brought. outside [the Temple Courtyard], he is exempt. [The rationale is that] it was not definitely established that a prohibition [was violated].33With regard to these sacrifices, it is possible that it will be discovered that the person definitely did sin. In such an instance, the sacrifice is not offered. If the sacrificial animal has not been slaughtered, it is left to pasture until it contracts a blemish. If it was slaughtered, its blood is poured down the drainage channel. Since there is a possibility of this taking place, the animal is not deemed a sacrificial animal in the full sense and one is not liable for slaughtering it or offering it.
The Ra'avad accepts the Rambam's ruling with regard to a sin-offering of fowl brought because of a doubt since only its blood is offered on the altar, but not its body. Hence, there is room to free one from the obligations involved with a sacrificial animal. Nevertheless, he argues, a conditional guilt-offering is offered on the altar. Hence one should be liable for slaughtering and offering it outside the Temple. The Radbaz and the Kessef Mishneh question the Ra'avad's objection, noting that the Rambam's ruling has its basis in Keritot 18a.
When a guilt-offering for one afflicted by tzara'at was slaughtered outside [the Temple Courtyard], but not for the desired intent, [the one who slaughters it] is liable. [The rationale is that] since [when such a sacrifice is] not [slaughtered] for the desired intent in [the Temple Courtyard], it is deemed appropriate and acceptable, as will be explained.34As stated in Hilchot Pesulei HaMukdashim 15:1, with the exception of a sin-offering or a Paschal sacrifice, whenever a sacrificial animal was slaughtered for the sake of an offering other the one for which it was intended, it is acceptable, but it does not fulfill the obligation of the owner (see also ibid.:20). Since the sacrifice would be acceptable if it was offered in the Temple, the person is liable for slaughtering it outside.
Whenever one is exempt for slaughtering a sacrificial [animal] outside the [Temple Courtyard], one is also exempt for offering it there.

[The following rules apply if] one slaughters the two goats offered on Yom Kippur35The goat sent to Azazel and its pair whose blood is taken into the Holy of Holies. See Hilchot Avodat Yom HaKippurim 1:1. outside [the Temple Courtyard]. Before [the High Priest] recites the confessional over them,36More precisely, the confessional is recited only over the one sent to Azazel (ibid. 4:2).
The Ra'avad objects to the Rambam's ruling, maintaining that the matter is dependent not only the confessional, but on the lottery in which the goats are designated for their respective purposes. The Radbaz and the Kessef Mishneh explain that the Rambam's ruling is based on Zevachim 113a. Although there are other interpretations of that passage, the Rambam has a foundation for his decision.
he is liable for both of them,37Or for either of them, were he to slaughter only one. since [they are both] fit to come before God for the confessional. After [the High Priest] recited the confessional, one is exempt for slaughtering [the goat] that is sent [to Azazel], because it is no longer fit to come before God [as a sacrifice].

When one slaughters [animals designated as] peace-offerings outside [the Temple Courtyard], before the gates of the Temple building are opened, he is exempt, for a [necessary] deed is lacking. [Only] afterwards are they fit to be offered before God, as we explained.38See Chapter 5, Halachah 5, which states that the gates to the Temple building must be open for the slaughter of peace offerings to be acceptable.
One who slaughters a Paschal sacrifice outside [the Temple Courtyard] - even during the other days of the year, whether for the sake of the Paschal sacrifice or for another purpose39The Kessef Mishneh emphasizes that this applies only during the remainder of the year. The rationale is that as explained below, during the remainder of the year, an animal designated as a Paschal sacrifice is considered as a peace-offering and a peace-offering is not disqualified if it is not offered for the desired intent. On the day preceding Pesach, when the Paschal sacrifice is offered, it is unacceptable if it is not offered for the desired intent. Hence on that date, were someone to slaughter an animal designated for this purpose for the sake of another sacrifice outside the Temple Courtyard, he would not be liable. - is liable. [The rationale is that] during the remainder of the year, a Paschal sacrifice [that is offered] is considered as a peace-offering.40See Hilchot Korban Pesach 4:7. Since it is considered as a peace-offering, just as one is liable for slaughtering an animal designated as a peace-offering outside the Temple Courtyard, so too, he is liable for slaughtering such an animal.

When one stole [an animal] and consecrated it, and afterwards, slaughtered it outside [the Temple Courtyard], he is liable.43Even though the animal did not belong to him and hence, he had no right to consecrate it, our Sages considered it as his own so that he would be liable for karet. See Gittin 55b. The Kessef Mishneh raises questions on the Rambam's ruling based on that passage, but Rav Yosef Corcus resolves the Rambam's decision. From which time was it considered in his property with regard to his being liable for karet for it? From the time he consecrated it.
[The above applies] provided he slaughtered it after [the owner] despaired of its return. [If he slaughtered it] before then, by contrast, the consecration is not effective.44For then it is still considered as belonging to the owner. Hence, the thief's consecration is not effective. See Hilchot Issurei Mizbeiach 5:7 which speaks of the disqualification of a thief's offering. From Hilchot Geneivah 2:6, it appears that the thief must have also consecrated the animal after the owner's despair and not before. Otherwise, the consecration would not be effective.

If the entire body of the animal was outside [the Temple Courtyard] and its neck was inside and one slaughtered it, he is liable,45Karet or lashes for slaughtering the animal outside the Temple Courtyard. as [Leviticus 17:3] states: "[Any man]...who will slaughter an ox, a sheep, or a goat in the camp or who will slaughter outside the camp... [and he has not brought it as an offering]." This applies whether the one who slaughters is standing in the Temple [Courtyard] and the animal's neck was inside, but the remainder of its body was outside, or its body was inside and its neck was outside. He is liable unless the animal was entirely within the Temple [Courtyard], as [implied by ibid.:9]: "And he will not bring it to the entrance of the Tent of Meeting."46The Kessef Mishneh notes that Zevachim 107b uses this prooftext to teach the following concept: that one who slaughters on the roof of the Temple Building is exempt. Hence he suggests that a printing error crept into the Mishneh Torah and that the text should be amended to fit the Talmud's teaching. This conception is not, however, shared by all authorities. If, however, one slaughters on the roof of the Temple Building, even though it is not fit for sacrifice at all,47See Chapter 5, Halachah 4. he is exempt.48For he did not slaughter the animal outside the Temple Courtyard.

Two people who held a knife and slaughtered [a sacrificial animal] outside [the Temple Courtyard] are exempt,49Note the contrast to Chapter 19, Halachah 12, with regard to offering an animal as a sacrifice. for [the prooftexts] say "who will slaughter" "or who will slaughter"50The verses use a singular form. [implying] one and not two.51The commentaries note that although the Rambam's ruling has a source in Zevachim 108a and in the Sifri, his process of exegesis is different than that used in those sources.
When one slaughters a sacrificial animal outside [the Temple Courtyard] even though he had no intention of sacrificing this animal to God,52But instead was slaughtering it for mundane purposes. he is liable.53In this as well, there is a contrast to offering an animal as a sacrifice, as stated in Chapter 19, Halachah 1. This is [implied by the prooftext]: "It will be considered as [the shedding of] blood for that person. He has shed blood."54Here also, the Rambam's method of exegesis is different from that of his apparent source, Zevachim 108b. Significantly, in his Commentary to the Mishnah (Zevachim 13:3), he cites the method of exegesis used by the Talmud. [One can infer that] even if [the person slaughtering] thinks of the blood [from the sacrificial animal] as blood that was shed55Literally, "poured out." and not as a sacrifice, he is liable.

A person who slaughters [a sacrificial animal] outside [the Temple Courtyard] at night is liable, since slaughtering an animal56I.e., an ordinary animal, not one designated as a sacrifice. is acceptable at night. Similarly, if, at night, one offered as a sacrifice [an animal] he slaughtered at night outside [the Temple Courtyard], he is liable for offering it as a sacrifice.57The Ra'avad maintains that the person is exempt in such a situation. The Radbaz justifies the Rambam's ruling, explaining that there is a fundamental difference between slaughtering an animal inside the Temple Courtyard and slaughtering it outside. When it is slaughtered inside the Temple Courtyard at night, it is disqualified as a sacrifice, because of it having been slaughtered at night and hence, it is not acceptable wherever it was offered. If, by contrast, it was slaughtered outside the Temple Courtyard, it becomes placed in the category of animals slaughtered in such a place. Hence the time when it is offered is not significant. The Kessef Mishneh also justifies the Rambam's approach.
If, however, one slaughtered [a sacrificial animal] inside [the Temple Courtyard] at night and offered it as a sacrifice outside,58Even during the following day (Kessef Mishneh). he is exempt. [The rationale is that] he offered merely an unacceptable article,59See Hilchot Pesulei HaMukdashim 3:6. for there is no conception of acceptable slaughter in the Temple at night.60See Chapter 4, Halachah 1. Similarly, if one received [the blood of a sacrificial animal] with an ordinary vessel61This disqualifies the sacrifice, for as stated in Chapter 5, Halachah 1, the blood of a sacrificial animal must be received in a sacred vessel. inside [the Temple Courtyard], but poured it [on an altar] outside, he is exempt.62For the animal was no longer acceptable as a sacrifice.

Similarly, when a person performs melikah on a fowl outside [the Temple Courtyard], he is exempt.63For the prooftext defining the prohibition (Leviticus 17:3 mentions slaughter, but not melikah (Zevachim 107a). If he offered it [as a sacrifice there], he is exempt. If he performs melikah on a fowl inside [the Temple Courtyard], but offered it outside, he is liable for offering it.64This is equivalent to slaughtering an animal inside the Temple Courtyard and offering it outside.
If one slaughtered [a fowl] in [the Temple Courtyard]65Thus disqualifying it, for in the Temple Courtyard, a fowl should be killed through melikah not ritual slaughter. and offered it outside, he is exempt, for he offered something that is not fit to be offered. If he slaughtered the fowl outside [the Temple Courtyard] and offered it outside, he is liable twice,66Both for slaughtering and for offering. because slaughtering a fowl outside [the Temple Courtyard] is acceptable. It is comparable to performing melikah inside.
