The Book of Numbers, called also "In the wilderness," opens with the second month of the second year after the exodus, and goes on to the arrival of the tribes in the plains of Moab by the Jordan. As a whole it may be said to carry out the historical and religious ideas of Exodus and Leviticus: and both the history and the legislation flow into three main channels. They go to establish the separateness of Israel as a people, the separateness of the tribe of Levi and the priesthood, and the separateness and authority of Jehovah. The first of these objects is served by the accounts of the census, of the redemption of the first-born, the laws of national atonement and distinctive dress, and generally the Divine discipline of Israel recorded in the course of the book. The second line of purpose may be traced in the careful enumeration of the Levites; the minute allocation of duties connected with the tabernacle to the Gershonites, the Kohathites, and the Merarites; the special consecration of the Aaronic priesthood; the elaboration of ceremonials requiring priestly service; and various striking incidents, such as the judgment of Korah and his company, and the budding of Aaron's almond twig. Lastly, the institution of some cleansing rites, the sin offering of chap. xix. for example, the details of punishment that fell upon offenders against the law, the precautions enjoined with regard to the ark and the sanctuary, together with the multiplication of sacrifices, went to emphasise the sanctity of worship and the holiness of the unseen King. The book is sacerdotal; it is marked even more by a physical and moral Puritanism, exceedingly stringent at many points.
The whole system of religious observance and priestly ministration set forth in the Mosaic books may seem difficult to account for, not indeed as a national development, but as a moral and religious gain. We are ready to ask how God could in any sense have been the author of a code of laws imposing so many intricate ceremonies, which required a whole tribe of Levites and priests to perform them. Where was the spiritual use that justified the system, as necessary, as wise, as Divine? Inquiries like these will arise in the minds of believing men, and sufficient answer must be sought for.
In the following way the religious worth and therefore the inspiration of the ceremonial law may be found. The primitive notion that Jehovah was the exclusive property of Israel, the pledged patron of the nation, tended to impair the sense of His moral purity. An ignorant people inclined to many forms of immorality could not have a right conception of the Divine holiness; and the more it was accepted as a commonplace of faith that Jehovah knew them alone of all the families of the earth, the more was right belief towards Him imperilled. A psalmist who in the name of God reproves "the wicked" indicates the danger: "Thou thoughtest that I was altogether such an one as thyself." Now the priesthood, the sacrifices, all provisions for maintaining the sanctity of the ark and the altar, and all rules of ceremonial cleansing, were means of preventing that fatal error. The Israelites began without the solemn temples and impressive mysteries that made the religion of Egypt venerable. In the desert and in Canaan, till the time of Solomon, the rude arrangements of semi-civilised life kept religion at an everyday level. The domestic makeshifts and confusion of the early period, the frequent alarms and changes which for centuries the nation had to endure, must have made culture of any kind, even religious culture, almost impossible to the mass of the people. The law in its very complexity and stringency provided a needful safeguard and means of education. Moses had been acquainted with a great sacerdotal system. Not only would it appear to him natural to originate something of a like kind, but he would see no other means of creating in rude times the idea of the Divine holiness. For himself he found inspiration and prophetic power in laying the foundation of the system; and once initiated, its development necessarily followed. With the progress of civilisation the law had to keep pace, meeting the new circumstances and needs of each succeeding period. Certainly the genius of the Pentateuch, and in particular of the Book of Numbers, is not liberating. The tone is that of theocratic rigour. But the reason is quite clear; the development of the law was determined by the necessities and dangers of Israel in the exodus, in the wilderness, and in idolatrous, seductive Canaan.
Opening with an account of the census, the Book of Numbers evidently stood, from the first, quite distinct from the previous books as a composition or compilation. The mustering of the tribes gave an opportunity of passing from one group of documents to another, from one stage of the history to another. But the memoranda brought together in Numbers are of various character. Administrative, legislative, and historical sources are laid under contribution. The records have been arranged as far as possible in chronological order; and there are traces, as for instance in the second account of the striking of the rock by Moses, of a careful gathering up of materials not previously used, at least in the precise form they now have. The compilers collected and transcribed with the most reverent care, and did not venture in any case to reject. The historical notices are for some reason anything but consecutive, and the greater part of the time covered by the book is virtually passed over. On the other hand some passages repeat details in a way that has no parallel in the rest of the Mosaic books. The effect generally is that of a compilation made under difficulties by a scribe or scribes who were scrupulous to preserve everything relating to the great lawgiver and the dealings of God with Israel.
Recent criticism is positive in its assertion that the book contains several strata of narrative; and there are certain passages, the accounts of Korah's revolt and of Dathan and Abiram, for instance, where without such a clew the history must seem not a little confused. In a sense this is disconcerting. The ordinary reader finds it difficult to understand why an inspired book should appear at any point incomplete or incoherent. The hostile critic again is ready to deny the credibility of the whole. But the honesty of the writing is proved by the very characteristics that make some statements hard to interpret and some of the records difficult to receive. The theory that a journal of the wanderings was kept by Moses or under his direction is quite untenable. Dismissing that, we fall back on the belief that contemporary records of some incidents, and traditions early committed to writing formed the basis of the book. The documents were undoubtedly ancient at the time of their final recension, whensoever and by whomsoever it was made.
By far the greater part of Numbers refers to the second year after the exodus from Egypt, and to what took place in the fortieth year, after the departure from Kadesh. Regarding the intermediate time we are told little but that the camp was shifted from one place to another in the wilderness. Why the missing details have not survived in any form cannot now be made out. It is no sufficient explanation to say that those events alone are preserved which struck the popular imagination. On the other hand, to ascribe what we have to unscrupulous or pious fabrication is at once unpardonable and absurd. Some may be inclined to think that the book consists entirely of accidental scraps of tradition, and that inspiration would have come better to its end if the religious feelings of the people had received more attention, and we had been shown the gradual use of Israel out of ignorance and semi-barbarism. Yet even for the modern historical sense the book has its own claim, by no means slight, to high estimation and close study. These are venerable records, reaching back to the time they profess to describe, and presenting, though with some traditional haze, the important incidents of the desert journey.
Turning from the history to the legislation, we have to inquire whether the laws regarding priests and Levites, sacrifices and cleansings, bear uniformly the colour of the wilderness. The origins are certainly of the Mosaic time, and some of the statutes elaborated here must be founded on customs and beliefs older even than the exodus. Yet in form many enactments are apparently later than the
