When the use of the Hebrew term rendered "leprosy" is examined, in this law and elsewhere, it certainly seems to be used with great definiteness to describe a disease which had as a very characteristic feature a whitening of the skin throughout, together with other marks common to the early stages of leprosy as given in this chapter. Only in ver. 12 does the Hebrew word appear to be applied to a disease of a different character, though also marked by the whitening of the skin. As for the symptoms indicated, the undoubted absence of many conspicuous marks of leprosy may be accounted for by the following considerations. In the first place, with a single exception (vv. 9-11), the earliest stages of the disease are described; and, secondly, it may reasonably be assumed that, through the desire to ensure the earliest possible separation of a leprous man from the congregation, signs were to be noted and acted upon, which might also be found in other forms of skin disease. The aim of the law is that, if possible, the man shall be removed from the camp before the disease has assumed its most unambiguous and revolting form. As for the omission to mention the insensibility of the skin of the leper, this seems to be sufficiently explained when we remember that this symptom is characteristic of only one, and that not the most fatal, variety of the disease. But, it has also been urged, that elsewhere in the Scripture the so-called lepers appear as mingling with other people--as, for example, in the case of Naaman and Gehazi--in a way which shows that the disease was not regarded as contagious; whence it is inferred, again, that the leprosy of which we read in the Bible cannot be the same with the disease which is so called in our time. But, in reply to this objection, it may be answered that even modern medical opinion has been by no means as confident of the contagiousness of the disease--at least, until quite recently--as were people in the middle ages; nor, moreover, can we assume that the prevention of contagion must have been the chief reason for the segregation of the leper, according to the Levitical law, seeing that a like separation was enjoined in many other cases of ceremonial uncleanness where any thought of contagion or infection was quite impossible.
