Zevachim 14:1 - 14:2

פרת חטאת – the red heifer. It is stated there (Numbers 19:9): “[A man who is pure shall gather up the ashes of the cow and deposit them outside the camp in a pure place…]. It is for purification.”

חוץ מגתה (outside of its marked-off space – the phrase also appears in Tractate Parah, Chapter 4, Mishnah 2) – the pile of wood on the altar in the Temple that are arranged like a vat (i.e., marked off space) that they make for it in the place that they slaughter it on the Mount of Olives opposite the entrance of the Temple (i.e., the Hall containing the golden altar). But if he slaughtered it outside of that place, it is invalid. But he is not liable for it because one can slaughter Holy Things outside [the Temple], for the All-Merciful exempted him since it is written (Leviticus 17:4): “and does not bring it to the entrance of the Tent of Meeting [to present it as an offering to the LORD, before the LORD’s Tabernacle, bloodguilt shall be imputed to that man: he has shed blood; that man shall be cut off from among his people.],” but since Scripture was strict to punish him that he did not bring it [to the entrance of the Tent of Meeting], one learns from it that while standing to bring it in [to the entrance of the Tent of Meeting] is what Scripture is speaking about.

כל שאינו ראוי לבוא – etc. that will not offer a sacrifice in the future.

בלא תעשה – since they are worthy to come [before the altar of God] at another time, they do not suffer extirpation, but rather it is a mere negative commandment of (Deuteronomy 12:8): “You shall not act at all as we now act here, [every man as he pleases.”

תורים שלא הגיע זמנן – [as it is taught in the Mishnah (note: but it is NOT a Mishnah, but rather a Baraita; the Mishnah is found in Tractate Hullin, Chapter 1, Mishnah 5 on 22a) of Tractate Hullin (22b): when their plumage is glittering, they are kosher, but before this they are invalid], for we require large turtle-doves and not small ones.

ובני יונה שעבר זמנן – small pigeons and not large ones, and they are invalid from the incipient stage of brightening plumage and onward (see Tractate Hullin, Chapter 1, Mishnah 5).

בלא תעשה – since for they are worthy after the time [for the offering of he sacrifice] there is for them a negative commandment to slaughtered them outside [the Temple courtyard].

אותו ואת בנו – that he slaughtered one of them (either the parent-bird or the offspring) and he came to offer up the second on the second day, but it is prohibited because of (Leviticus 22:28): “[However, no animal from the herd or from the flock] shall be slaughtered on the same day with its young.”

מחוסר זמן (an offering that cannot be offered because the time for it be offered has not yet arrived (i.e., for an animal not yet eight days old, or a peace-offering is offered before the Temple gates were opened.) – whether it is because it is lacking time in its body that it was not seven days with its mother, or whether the owners are lacking time, as will be explained further (see the next Mishnah). And it is necessary to teach the dispute between Rabbi Shimon and the Rabbis in all of these [three segments of the Mishnah], for it if (i.e., the Mishnah) only mentioned to us regarding animals with a blemish, in that, the Rabbis state because they are repulsive, but turtle-doves and pigeons are not repulsive. I would say that they agree [on this] with Rabbi Shimon. But if it (i.e., the Mishnah) mentioned only turtle-doves and pigeons, because they were not appropriate/eligible and superseded, I would say that Rabbi Shimon agrees with the Rabbis. But if it (i.e., the Mishnah) teaches these two, because of the invalid (i.e., intrinsic) nature of its body, but the parent animal and its offspring which is invalid eternally (i.e., as a result of an accident of time), they would bring them, I would say that the Rabbis agree with Rabbi Shimon, hence it is necessary, but the Halakha is not according to Rabbi Shimon (see Tractate Zevakhim 114a).
