Sifrei Mitzvot untuk Bilangan 5:3

For thirty-three days she will remain [in the status] that the blood [she sees] is ritually pure. She shall not touch anything holy and she shall not come into the Sanctuary, until the days of her purity are completed.

That He prohibited any impure person from entering the Sanctuary (the Tabernacle) - and everything that is similar to it for [all] the generations: All of the courtyard and from the Gate of Nikanor onwards, which is the courtyard of the Israelites. And that is His, may He be exalted, saying, "so that they shall not render their camp impure" (Numbers 5:3). And in the Gemara, Makkot (Makkot 14b), they said, "One who entered the Temple [while] impure - a punishment is written and a prohibition is written: The punishment - 'he has rendered impure the Tabernacle of the Lord, and that soul shall be excised' (Numbers 19:13). The prohibition - 'so that they shall not render their camp impure.'" And in the Mekhilta: "'Command the Children of Israel to send away from the camp' - is with a positive commandment. But from where [do we know] it is [also] with a negative commandment? You can say, 'so that they shall not render their camp impure.'" And the prohibition about this content has already been repeated with different language; and that His, may He be exalted, saying about a woman who has given birth, "and she shall not come into the sanctuary" (Leviticus 12:4). And in the [Sifra] (Sifra, Tazria Parashat Yoledet, Section 1:1), they said, "Because it is stated (Leviticus 15:31), 'And you shall separate the Children of Israel,' I would understand, whether from its front or from its back, and one is impure, he is liable. [Hence] we learn to say, 'and she shall not come into the sanctuary.'"And there it is explained that the law of a woman who has given birth and the law of other impure people is the same with regards to this. And they [also] said in the [Sifra] (Sifra, Acharei Mot, Chapter 12:13-14), about His saying "But if he does not wash and does not bathe his body" (Leviticus 17:16), "How is this? For [failure in] the bathing of his body, the punishment is excision, but for [failure in] the washing of his clothes, it is with forty [lashes]. And from where [do we know] that it is speaking here of his rendering the sanctuary and its consecrated objects impure? It prohibited and punished, etc." Behold it has been made clear that one who transgresses this negative commandment - if he was intentional, he is punished with excision; and if he was inadvertent, he must bring a variable offering, as we explained in Commandment 72 of the Positive Commandments. And the regulations of this commandment have already been explained at the beginning of Shevuot and in Horayot. (See Parashat Nasso; Mishneh Torah, Admission into the Sanctuary 3.)
