The Hebrew word for leprosy (tsara’ath) was a nonspecific term for any skin condition, which could also refer to mildew and mould on clothes or houses. Moses’ Law included extensive regulations for leprosy on people or their possessions. In general, anyone with an open skin lesion was considered unclean, whether it was true leprosy or something else. Lepers (those with skin lesions) had to live in isolation and shout, “Unclean! Unclean!” when around others. When a skin disorder resolved, the person had to be examined by a priest and be ceremonially cleaned. After bathing, shaving, washing one’s clothes, and offering sacrifices, the person could then officially rejoin the community. However, unlike other skin conditions, leprosy rarely self-resolved, so true lepers were typically outcasts for life.
