וְהַבֶּ֡גֶד אֽוֹ־הַשְּׁתִ֨י אוֹ־הָעֵ֜רֶב אֽוֹ־כָל־כְּלִ֤י הָעוֹר֙ אֲשֶׁ֣ר תְּכַבֵּ֔ס וְסָ֥ר מֵהֶ֖ם הַנָּ֑גַע וְכֻבַּ֥ס שֵׁנִ֖ית וְטָהֵֽר׃
And the garment, or the warp, or the woof, or whatsoever thing of skin it be, which thou shalt wash, if the plague be departed from them, then it shall be washed the second time, and shall be clean.
Mishnah Negaim
[A nega] that remained unchanged during the first week must be washed and isolated. One that remains unchanged during the second week must be burned. One that spread during the first or the second week must be burned. If it becomes dimmer in the beginning: Rabbi Ishmael says: it should be washed and isolated. But the sages say: he is not required [to do so]. If the nega became dimmer during the first week it must be washed and isolated. If it became dimmer during the second week it must be torn out, and that which is torn out must be burnt, and it is necessary for a patch to be put on. Rabbi Nehemiah says: a patch is not necessary.
