Leviticus 13:38-39

If a man also or a woman have in the skin of their flesh bright spots, even white bright spots;

If a man also or a woman have in the skin of their flesh bright spots. This modification of the leprosy is distinguished by a dull-white colour [it is called lªbaanot (H3836) bohaq (H933), a 'freckled spot'], and it is entirely a cutaneous disorder, not uncommon in the East (Niebuhr, 'Descrip. de l'Arabie,' p. 119), but never injuring the constitution. It is described as not penetrating below the skin of the flesh, and as not rendering necessary an exclusion from society. It is by medical writers termed 'lepra,' which is often confounded with leprosy, although entirely different. It is evident, then, this common form of leprosy was not contagious, otherwise Moses would have prescribed as strict a quarantine in this as in the other cases. And hereby we see the great superiority of the Mosaic law-which so accurately distinguished the characters of the leprosy, and preserved to society the services of those who were labouring under the uncontagious forms of the disease-over the customs and regulations of Eastern countries in the present day, where all lepers are indiscriminately proscribed, and are avoided as unfit for free contact with their fellow-men.
