LEPROSY. This term, as used in Scripture, seems to include not only true leprosy ( elephantiasis ) probably the disease of Job but also such skin diseases as psoriasis , ring-worm, and vitiligo . For the priestly regulations as to the diagnosis of the disease and the treatment of lepers, see art. Clean and Unclean, § 5. The ‘leprosy’ in garments ( Leviticus 13:47 ff.) seems to be an effect of fungus or mildew, while that in houses ( Leviticus 14:34 ff.) is probably dry-rot.
