The Portion of Tazriah
Hashem spoke to Moshe, saying:
Such is the procedure for eruptive affections of cloth, woolen or linen, in warp or in woof, or of any article of skin, for pronouncing it clean or unclean.
The portion opens with the ritual laws of a woman who gives birth, but the bulk of the content discusses the identification and quarantine of the metzorah, or leper. Unlike the medical affliction, Biblical tzaraat, or leprosy, can also affect clothing or buildings.
