The commandment of the matter of ailments of clothing: To act with ailments of clothing like the statute written in the section of the Torah, as it is stated (Leviticus 13:47), “And the garment that has an ailment in it, etc.” And this commandment includes all of the laws of the tsaraat of clothing: how they become impure and how they do not become impure; which ones of them require quarantine, or tearing or burning, or washing and purification.
It is from the roots of the commandment that God wanted in His great goodness to chasten us, ‘like a man chasten his child.’ As this matter is not natural, but [rather] a sign with the holy people, in order that they learn and take rebuke in the changing of the items that are particularly for their use — and they are clothes of wool and flax, as most usage of people is with them — and they repent through this from their evil way, before the tsaraat breaks out also in their bodies.
From the laws of the commandment is that which they, may their memory be blessed, said (Sifra, Tazria, Parashat Nega’im, Chapter 13:1) that only clothes of wool and flax alone become impure with aliments; and the measure of their impurity is a split bean, like the measure in a person. And there are three signs of impurity with them (Mishnah Negaim 3:7): deep green; deep red; and spreading — the understanding of deep green is green among the greens, like the wing of a peacock; and of deep red is red among the reds, like crimson fabric. And the laws of spreading (Mishnah Negaim 11:7); the law of green that spread red or red that spread green; the law that all [cloths] are fitting to become impure — as they, may their memory be blessed, said (Mishnah Negaim 11:11) that it becomes impure with ailments, even though it does not become impure as the base (midras) of a zav — like sails of a ship, a partition, the decorative piece of a hairnet, scribes’ handkerchiefs, a belt, the laces of a shoe or of a sandal that has the width of a split bean, and similar to them, and there is no need to say other [cloths] like bedspreads and pillows; and the rest of its details are elucidated in [the Order] of Tahorot, and most of them are in Tracate Negaim. (See Mishneh Torah, Laws of Defilement by Leprosy 12.)
And [it] is practiced with the clothes of males and females. And one who transgresses it and does not act in this matter like the law that is written in [this] section of the Torah has violated a positive commandment.
מִצְוַת עִנְיַן נִגְעֵי בְּגָדִים – לַעֲשׂוֹת בְּנִגְעֵי בְּגָדִים כַּמִּשְׁפָּט הַכָּתוּב בַּפָּרָשָׁה. שֶׁנֶּאֱמַר (ויקרא יג מו) וְהַבֶּגֶד כִּי יִהְיֶה בוֹ נֶגַע וְגוֹ'. וּמִצְוָה זוֹ כּוֹלֶלֶת כָּל דִּינֵי צָרַעַת בְּגָדִים אֵיךְ יִטַּמְּאוּ וְאֵיךְ לֹא יִטַּמְּאוּ, וּמָה מֵהֶם צָרִיךְ הֶסְגֵּר אוֹ קְרִיעָה אוֹ שְׂרֵפָה וּרְחִיצָה וְטָהֳרָה.
