Leviticus 13

Leviticus 13:1-59 . THE LAWS AND TOKENS IN DISCERNING LEPROSY.

2. When a man shall have in the skin, &c.--The fact of the following rules for distinguishing the plague of leprosy being incorporated with the Hebrew code of laws, proves the existence of the odious disease among that people. But a short time, little more than a year (if so long a period had elapsed since the exodus) when symptoms of leprosy seem extensively to have appeared among them; and as they could not be very liable to such a cutaneous disorder amid their active journeyings and in the dry open air of Arabia, the seeds of the disorder must have been laid in Egypt, where it has always been endemic. There is every reason to believe that this was the case: that the leprosy was not a family complaint, hereditary among the Hebrews, but that they got it from intercourse with the Egyptians and from the unfavorable circumstances of their condition in the house of bondage. The great excitement and irritability of the skin in the hot and sandy regions of the East produce a far greater predisposition to leprosy of all kinds than in cooler temperatures; and cracks or blotches, inflammations or even contusions of the skin, very often lead to these in Arabia and Palestine, to some extent, but particularly in Egypt. Besides, the subjugated and distressed state of the Hebrews in the latter country, and the nature of their employment, must have rendered them very liable to this as well as to various other blemishes and misaffections of the skin; in the production of which there are no causes more active or powerful than a depressed state of body and mind, hard labor under a burning sun, the body constantly covered with the excoriating dust of brick fields, and an impoverished diet--to all of which the Israelites were exposed while under the Egyptian bondage. It appears that, in consequence of these hardships, there was, even after they had left Egypt, a general predisposition among the Hebrews to the contagious forms of leprosy--so that it often occurred as a consequence of various other affections of the skin. And hence all cutaneous blemishes or blains--especially such as had a tendency to terminate in leprosy--were watched with a jealous eye from the first [GOOD, Study of Medicine]. A swelling, a pimple, or bright spot on the skin, created a strong ground of suspicion of a man's being attacked by the dreaded disease.
then he shall be brought unto Aaron the priest, &c.--Like the Egyptian priests, the Levites united the character of physician with that of the sacred office; and on the appearance of any suspicious eruptions on the skin, the person having these was brought before the priest--not, however, to receive medical treatment, though it is not improbable that some purifying remedies might be prescribed, but to be examined with a view to those sanitary precautions which it belonged to legislation to adopt.

3-6. the priest shall look on the plague in the skin of the flesh, &c.--The leprosy, as covering the person with a white, scaly scurf, has always been accounted an offensive blemish rather than a serious malady in the East, unless when it assumed its less common and malignant forms. When a Hebrew priest, after a careful inspection, discovered under the cutaneous blemish the distinctive signs of contagious leprosy, the person was immediately pronounced unclean, and is supposed to have been sent out of the camp to a lazaretto provided for that purpose. If the symptoms appeared to be doubtful, he ordered the person to be kept in domestic confinement for seven days, when he was subjected to a second examination; and if during the previous week the eruption had subsided or appeared to be harmless, he was instantly discharged. But if the eruption continued unabated and still doubtful, he was put under surveillance another week; at the end of which the character of the disorder never failed to manifest itself, and he was either doomed to perpetual exclusion from society or allowed to go at large. A person who had thus been detained on suspicion, when at length set at liberty, was obliged to "wash his clothes," as having been tainted by ceremonial pollution; and the purification through which he was required to go was, in the spirit of the Mosaic dispensation, symbolical of that inward purity it was instituted to promote.

7, 8. But if the scab spread much abroad in the skin--Those doubtful cases, when they assumed a malignant character, appeared in one of two forms, apparently according to the particular constitution of the skin or of the habit generally. The one was "somewhat dark" [ Leviticus 13:6 ]--that is, the obscure or dusky leprosy, in which the natural color of the hair (which in Egypt and Palestine is black) is not changed, as is repeatedly said in the sacred code, nor is there any depression in the dusky spot, while the patches, instead of keeping stationary to their first size, are perpetually enlarging their boundary. The patient laboring under this form was pronounced unclean by the Hebrew priest or physician, and hereby sentenced to a separation from his family and friends--a decisive proof of its being contagious.
