Robert Alexander Watson - The Expositor's Bible - The Book of Numbers

It may appear a strange thing that the precept, "Ye shall be holy; for I am holy," was affixed not only to moral duties but with almost the same force to ceremonial duties. We can understand this, however, when we trace the result of the priestly ordinances. They created religious care and feeling; and the end was gained not so much by directing attention, as we now do, to faults of conduct, defects of will, sins of injustice, impurity, intemperance, and the like, but by keeping up a scrupulous attention to matters not, properly speaking, either moral or immoral, not ethical as we say, which were yet declared to be of moment in religion. The moral law did its part. But to make the enforcement of moral statutes, many of which bore on desire and will, the only means of urging the fear of God, would have resulted practically in a very bare and desultory cultus. Among a comparatively rude people like the Israelites it would have been absurd to institute a religion consisting of "morality touched by emotion." For the mass of people still it is equally hopeless. There must be ordinances of prayer, praise, sacrament, and the duties which reach Godward through the Church. The value of the whole ceremonial system of the Mosaic law is clear from this point of view; and we need not wonder in the least at the nature of many provisions which, without grasp of the principle, we might reckon irksome and useless. The origin of some of the statutes is apparently hygienic; others again reach back to customs and beliefs of a very primitive world. But they are made part of the sacred law in order to enforce the conviction that the judgment of God enters into the whole of life, follows men wherever they go, decides as to their state with relation to Him hour by hour, almost moment by moment. The ceremonial law was a constant and strenuous lesson in regard to the omnipresence of God, and the oversight of human affairs by Him. It created a conscience of God's existence, His control, His superintendence of each life. And for a certain stage of the education of Israel this could be achieved in no other way. The moral and spiritual progress of a people, depending on the recognition of the authority of One who is of purer eyes than to behold iniquity, depends also, of necessity, on the sense of His oversight of human life at every point.

The rigidness of the law which excluded lepers from the camp and afterwards from the cities had its necessity in the presumed nature of their disease. Leprosy was regarded as contagious, and practically incurable by any medical appliances, requiring to be kept in check by strenuous measures. Care for the general health meant hardship to the lepers; but this could not be avoided. From friends and home they were sent forth to live together as best they might, and spend what remained of life in almost hopeless separation. The authority of Moses is attached to the statute of exclusion, and there can be no doubt of its great antiquity. In Leviticus there are detailed enactments regarding the disease, some of which contemplate its decay and provide for the restoration to privilege of those who had been cured. The ceremonies were complicated, and among them were sacrifices to be offered by way of "atonement." The leper was alienated from God, severed from the congregation as one guilty in the eye of the law (Lev. xiv. 12); and there can be no wonder that with this among other facts before him the writer of the Epistle to the Hebrews speaks of the law as having a mere "shadow of the good things to come."

And yet, in view of the malignant nature of the disease and the peril it caused to the general health, we must admit the wisdom of segregating those afflicted with leprosy. That Israel might be a robust people capable of its destiny, a rule like this was needful. It anticipated our modern laws made in harmony with advanced medical science, which require segregation or isolation in cases of virulent disease.

It has been affirmed that leprosy was from the first regarded as symbolic of moral disease, and that the legislation was from this point of view. There is, however, no evidence to support the theory. Indeed the conception of moral evil would have been confused rather than helped by any such idea. For although evil habits taint the mind and vice ruins it as leprosy taints and destroys the body; although the infectious nature of sin is fitly indicated by the insidious spread of this disease—one point in which there is no resemblance would make the symbol dangerously misleading. A few here and there were attacked by leprosy, and these with their blotched disfigured bodies were easily distinguished from the healthy. But this was in contrast with the secret moral malady by which all were tainted. The teaching that leprosy is a type of sin would make, not for morality, but for hypocrisy. The symptoms of a bad nature, like the signs of leprosy, would be looked for and found by every man in his neighbour, not in his own heart. The hypocrite would be encouraged in his self-satisfaction because he escaped the judgment of his fellow men. But the disease of sin is endemic, universal. The whole congregation was by reason of that excluded from the sanctuary of God.

According to the idea which underlies the priest law, leprosy did not typify sin; it meant sin. In no single place, indeed, is this directly affirmed. Yet the belief connecting bodily afflictions and calamities with transgressions implied it, and the fact that guilt offerings had to be made for the leper when he was cleansed. Again, in the cases of Miriam, of Gehazi, and of Uzziah, the punishment of sin was leprosy. Under the conditions of climate which often prevailed, the germs of this disease might rapidly be developed by excitement, especially by the excitement of immoral rashness. Here we may find the connection which the law assumes between leprosy and guilt, and the origin of the statute which made the intervention of the priests necessary. In their poor dwellings beyond camp and city wall the lepers lay under a double reproach. They were not only tainted in body but appeared as sinners above others, men on whom some divine judgment had fallen, as the very name of their disease implied. And not till One came who did not fear to lay His hand on the leprous flesh, whose touch brought healing and life, was the pressure of the moral condemnation taken away. Of many cases of leprosy He would have said, as of the blindness He cured: "Neither did this man sin, nor his parents."

Now is the law to be charged with creating a class of social pariahs? Is there any reason for saying that in some way the legislation should have expressed pity rather than the rigour which appears in the passage before us and other enactments regarding leprosy? It would be easy to bring arguments which would seem to prove the law defective here. But in matters of this kind civilization and Christian culture could not be forestalled. What was possible, what in the conditions that existed could be carried into effect, this only was commanded. These old enactments sprang out of the best wisdom and religion of the age. But they do not represent the whole of the Divine will, the Divine mercy, even as they were contemporaneously revealed. Add to the statutes regarding leprosy the other, "Thou shalt love thy neighbour as thyself," and those that enjoined kindness to the poor and provision for their needs, and the true tenor of the legislation will be understood. According to these laws there were to be no pariahs in Israel. It was a sad necessity if any were excluded from the congregation of God's people. The laws of brotherhood would insure for the wretched colony outside the camp every possible consideration. Denied access to God in festival and sacrifice, the lepers appealed to the humane feelings of the people. With their pathetic cry, "Unclean, unclean!" their loose hair and rent clothes, they confessed a miserable state that touched every heart. As time went on, the law of segregation was interpreted liberally. Even in the synagogues a place was set apart for the lepers. The kindly disposition promoted by the Mosaic institutions was shown thus, and in many other ways.
