3. Mose 13:4

Leprosy. - The law for leprosy, the observance of which is urged upon the people again in Deu 24:8-9, treats, in the first place, of leprosy in men: (a) in its dangerous forms when appearing either on the skin (vv. 2-28), or on the head and beard (Lev 13:29-37); (b) in harmless forms (Lev 13:38 and Lev 13:39); and (c) when appearing on a bald head (Lev 13:40-44). To this there are added instructions for the removal of the leper from the society of other men (Lev 13:45 and Lev 13:46). It treats, secondly, of leprosy in linen, woollen, and leather articles, and the way to treat them (Lev 13:47-59); thirdly, of the purification of persons recovered from leprosy (Lev 14:1-32); and fourthly, of leprosy in houses and the way to remove it (vv. 33-53). - The laws for leprosy in man relate exclusively to the so-called white leprosy, λεύκη λέπρα, lepra, which probably existed at that time in hither Asia alone, not only among the Israelites and Jews (Num 12:10.; Sa2 3:29; Kg2 5:27; Kg2 7:3; Kg2 15:5; Mat 8:2-3; Mat 10:8; Mat 11:5; Mat 26:6, etc.), but also among the Syrians (Kg2 5:1.), and which is still found in that part of the world, most frequently in the countries of the Lebanon and Jordan and in the neighbourhood of Damascus, in which city there are three hospitals for lepers (Seetzen, pp. 277, 278), and occasionally in Arabia (Niebuhr, Arab. pp. 135ff.) and Egypt; though at the present time the pimply leprosy, lepra tuberosa s. articulorum (the leprosy of the joints), is more prevalent in the East, and frequently occurs in Egypt in the lower extremities in the form of elephantiasis. Of the white leprosy (called Lepra Mosaica), which is still met with in Arabia sometimes, where it is called Baras, Trusen gives the following description: "Very frequently, even for years bef…

The next ceremonial uncleanness is that of the leprosy, concerning which the law was very large and particular; we have the discovery of it in this chapter, and the cleansing of the leper in the next. Scarcely any one thing in all the levitical law takes up so much room as this. I. Rules are here given by which the priest must judge whether the man had the leprosy or no, according as the symptom was that appeared. 1. If it was a swelling, a scab, or a bright spot (v. 1-17). 2. If it was a bile (Lev 13:18-23). 3. If it was in inflammation (Lev 13:24-28). 4. If it was in the head or beard (Lev 13:29-37). 5. If it was a bright spot (Lev 13:38, Lev 13:39). 6. If it was in a bald head (Lev 13:40-44). II. Direction is given how the leper must be disposed of (Lev 13:45, Lev 13:46). III. Concerning the leprosy in garments (Lev 13:47, etc.).
