xxi. 1), except in cases where defilement is necessary, and the

contrary would be unnatural. For it would be unnatural to abstain from approaching the dead body of a parent, child, or brother. As it was very necessary that the high-priest should always be in the Sanctuary, in accordance with the Divine command, “And it shall always be on his forehead” (Exod. xxviii. 38), he was not permitted to defile himself by any dead body whatever, even of the above-named relatives (Lev. xxi. 10–12). Women were not engaged in sacrificial service; the above law consequently does not apply to women; it is addressed to “the sons of Aaron,” and not to “the daughters of Aaron.” It was, however, impossible to assume that none of the Israelites made a mistake, by entering the Sanctuary, or eating hallowed things in a state of uncleanliness. It was even possible that there were persons who did this knowingly, since there are wicked people who commit knowingly even the greatest crimes; for this reason certain sacrifices were commanded as an atonement for the defilement of the Sanctuary and its hallowed things. They were of different kinds; some of them atoned for defilement caused ignorantly, others for defilement caused knowingly. For this purpose were brought the goats on the Festivals and the New-moon days (Num. xxviii. 15, 22, etc.), and the goat sent away on the Day of Atonement (Lev. xvi. 16), as is explained in its place (Mishnah Shebnot, i. 4). These sacrifices serve to prevent those who defiled the Sanctuary of the Lord knowingly from thinking that they had not done a great wrong; they should know that they obtained atonement by the sacrifice of the goat, as the Law says, “That they die not in their uncleanness” (Lev. xv. 31); “That Aaron may bear the iniquity of the holy things” (Exod. xxviii. 38). This idea is frequently repeated.

The uncleanness through leprosy we have already explained. Our Sages have also clearly stated the meaning thereof. All agree that leprosy is a punishment for slander. The disease begins in the walls of the houses (Lev. xiv. 33, seq.). If the sinner repents, the object is attained; if he remains in his disobedience, the disease affects his bed and house furniture; if he still continues to sin, the leprosy attacks his own garments, and then his body. This is a miracle received in our nation by tradition, in the same manner as the effect of the trial of a faithless wife (Num. v. 11, seq.). The good effect of this belief is evident. Leprosy is besides a contagious disease, and people almost naturally abhor it, and keep away from it. The purification was effected by cedar-wood, hyssop, scarlet thread, and two birds (Lev.
