Those rites might seem to relate only to the case of defilement by the dead. But among the directions as to them, there is one which is unequivocal and comprehensive. “The man that shall be unclean and shall not purify himself, that soul shall be cut off from among the congregation, because he hath defiled the sanctuary of the Lord; the water of separation hath not been sprinkled on him. He is unclean.”—Num. xix, 20. Here is no limitation nor exception of any kind. “The man that is unclean;” unclean, from whatever cause. Of all such, we are here certified that no lapse of time will bring cleansing. He must be purified before he can be clean. Till that is accomplished, his presence is a profanation of the sanctuary. It is, moreover, here declared that the one only mode of cleansing for all such was the water of separation, sprinkled according to the law. That this is a true interpretation, is confirmed by the testimony of Philo, of Alexandria, a Jewish writer of the highest reputation, contemporary with the apostles. Giving an account of the Levitical law, he distinguishes between defilements of the soul and of the body; by the latter meaning, ritual defilements. Of them, he says, in unrestricted terms, that the water of separation was appointed for purifying from those things by which a body is ritually defiled.[5] Footnote 5: Below p. 175. We shall presently see one notable example of this comprehensive interpretation of the law, in the case of the daughters of Midian. Their need of the rites of purifying did not arise out of any of the categories specified in the laws which we have examined. They were unclean, because they were idolatrous Gentiles (Compare Acts xv, 9); and were purified with the water of separation, because that was the general provision made for the unclean. This is further illustrated in the fact that all the spoil taken at the same time was also purified with this same water of separation. (Num. xxxi, 19-24.)
