Tsara'at is the technical term for the ritually significant condition traditionally rendered 'leprosy,' though modern scholarship recognizes it as a broader category of skin afflictions distinct from Hansen's disease. Its 35 occurrences cluster overwhelmingly in Leviticus 13-14 (29 times), where the Priestly code prescribes painstaking diagnostic procedures and purification rituals involving the priest, cedarwood, scarlet yarn, and hyssop. Outside the law codes, the word appears in the Naaman narrative (2 Kgs 5:3-27), where the Aramean general's healing becomes a sign of YHWH's power beyond Israel's borders. Remarkably, tsara'at can also afflict garments (Lev 13:47-59) and house walls (Lev 14:34-53), likely describing mold or fungus. Spanish and German renderings — 'tsaraat,' 'Haut-Krankheit' — reflect the modern move away from 'leprosy.'
