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 time of Moses; and it does not seem well to maintain that laws requiring what was next to impossible in the wilderness were, during the journey, given and enforced as they now stand by a wise legislator. Did Moses require, for instance, that five shekels, "of the shekel of the sanctuary," should be paid for the ransom of the first-born son of a household, at a time when many families must have had no silver and no means of obtaining it? Does not this statute, like another which is spoken of as deferred till the settlement in Canaan, imply a fixed order and medium of exchange? For the sake of a theory which is intended to honour Moses as the only legislator of Israel, is it well to maintain that he imposed conditions which could not be carried out, and that he actually prepared the way for neglect of his own code?
It is beyond our range to discuss the date of the compilation of Numbers as compared with the other Pentateuchal books, or the age of the "Jehovistic" documents as compared with the "Priests' Code." This, however, is of less moment, since it is now becoming clear that attempts to settle these dates can only darken the main question--the antiquity of the original records and enactments. The assertion that Exodus, Leviticus, and Numbers belong to an age later than Ezekiel is of course meant to apply to the present form of the books. But even in this sense it is misleading. Those who make it themselves assume that many things in the law and the history are of far older date, based indeed on what at the time of Ezekiel must have been immemorial usage. The main legislation of the Pentateuch must have existed in the time of Josiah, and even then possessed the authority of ancient observance. The priesthood, the ark, sacrifice and feast, the shewbread, the ephod, can be traced back beyond the time of David to that of Samuel and Eli, quite apart from the testimony of the Books of Moses. Moreover, it is impossible to believe that the formula "The Lord said unto Moses" was invented at a late date as the authority for statutes. It was the invariable accompaniment of the ancient rule, the mark of an origin already recognised. The various legislative provisions we shall have to consider had their sanction under the great ordinance of the law and the inspired prophetism which directed its use and maintained its adaptation to the circumstances of the people. The religious and moral code as a whole, designed to secure profound reverence towards God and the purity of national faith, continued the legislation of Moses, and at every point was the task of men who guarded as sacred the ideas of the founder and were themselves taught of God. The entire law was acknowledged by Christ in this sense as possessing the authority of the great lawgiver's own commission.
