Finally, in this passage (ver. 5), by the words "him and his sons for ever," which refer back to "the priest," a hereditary character of the priesthood is asserted. This phrase is remarkably parallel to that so frequently used by P, "Aaron and his sons"; and though we are not told in what family or families the priesthood was hereditary, it must have been so in some. But in x. 6, 7, the family of Aaron is mentioned by the Deuteronomist as having hereditary right to the priesthood at the central shrine. There can therefore be no doubt that in the time of the author of Deuteronomy priesthood was hereditary, perhaps in several families, but certainly in the family of Aaron.

The remaining point in these verses of chap. xviii. is the dues. As the whole tribe had no land, so the whole tribe had a share in the dues paid by the people to their Divine King. In vv. 3 ff. we have a statement of what these were. The whole tribe of Levi are to eat "the offerings of Yahweh made by fire, and His inheritance. And they shall have no inheritance among their brethren: Yahweh is their inheritance, as He hath spoken unto them." The only place in Scripture in which such a promise is given is Numb. xviii. 20, 24, so that these passages, if not referred to by the author of Deuteronomy, must be founded upon a tradition already old in his time. As the servants of Yahweh, the Levites were to be wholly Yahweh's care; as His representatives, they were to use for the supply of their needs all such portions of the offerings made to Him by fire as were not to be consumed on the altar. Their remaining provision was to be "His," i.e. Yahweh's, "inheritance," or rather "portion," or that which belongs to Him. Now Yahweh's "portion" consisted of all the other sacred dues (besides the sacrifices) which should be paid to Yahweh, such as the tithes, the firstlings, and the firstfruits. On these the whole tribe of Levi was to live, and so be free to give their time to the special business of the sanctuary, and to related duties, in so far as they were called upon.

But there were to be distinctions. In vv. 3-5 we have a special statement of what was to be paid by the people to the priests, i.e. the sacrificing priests. Of every animal offered in sacrifice, except those offered as whole burnt-offerings, they were to receive "the shoulder, the two cheeks, and the maw," all choice pieces. Further, they were to receive the "firstfruits of corn, wine, oil, and the first of the fleece of the sheep." For the priests of one sanctuary these would be quite provision enough, though the word translated "firstfruits," rēshith, is very indefinite, and probably meant much or little, according as the donor was liberal or churlish. But how does this agree with that which is bestowed upon the priests according to the Priest Codex? In the passage corresponding to this (Lev. vii. 31-34) the wave breast and the heave thigh are the portions which are to be bestowed upon "Aaron the priest and his sons, as a due for ever from the children of Israel"; and where the firstfruits are dealt with (Numb. xviii. 12 ff.) "the first of the fleece of the sheep" is not mentioned. That is an addition made by the author of Deuteronomy; but what of "the shoulder, the two cheeks, and the maw"? Are they a substitute for the "wave breast and the heave thigh," or are they an addition? If we hold that the laws in the Pentateuch were all given by Moses in the wilderness, and in the order in which they stand, it will be most natural to think that what we have here is meant to be an addition to what Numbers prescribes. But if it is established that Deuteronomy is a distinct work, written at a different period from the other books of the Pentateuch, then, though there is not sufficient evidence to justify a dogmatic decision on either side, the weight of probability is in favour of the supposition that the Deuteronomic provision is a substitute, or at least an alternative, for what we have in Numbers. The fact that the prescription in Numbers is not repeated makes for that view, as well as the fact that Deuteronomy does not as a rule tend to increase the burdens on the people. Keil's view, that Deuteronomy and Numbers are dealing with quite different sacrifices, will hardly stand examination. He thinks that the feasts at which the firstlings, turned into money, and the third-year tithes were eaten, are referred to here, while in Numbers it is the ordinary peace-offerings which are dealt with. But the postponed firstlings were eaten at the sanctuary, and would consequently come under the head of ordinary sacrifices; and the third-year tithes were eaten in the local centres, so that the bringing of the priestly portions would be as difficult in this case as in the case of the slaughterings for ordinary meals, which Keil, partly for that reason, thinks cannot be referred to here. On the whole, the best opinion seems to be that Deuteronomy has here different prescriptions from those in Numbers, and that probably there is a considerable interval of time between the two.

In vv. 6-8 the Levite as distinguished from the priest is dealt with, though by no means fully. Only in one respect are special regulations given. When such an one came to do duty at the central sanctuary, he was to receive his share of the sacrifices with the rest.

In Chapter I. the main outlines of the Deuteronomic system of priestly arrangements have been placed alongside those of the Book of the Covenant and JE, and those of P, with a view to decide whether they could all have been the work of one lawgiver's life. Here they must be compared in order that we may ascertain whether a view of the development of the priestly tribe which will do justice to these various documents and their provisions can be suggested.

Some schools of critics offer the hypothesis that there was no special priesthood till late in the time of the kings. From the beginning, they say, the head of each household was the family priest, and secular men, such as the kings, and men of other tribes than the Levites, could be and were priests, and offered sacrifice even at Jerusalem. With Deuteronomy the tribe of Levi was established as the priestly tribe, and only after the Exile was priesthood restricted to the sons of Aaron. But this scheme does justice to one set of passages only at the expense of another. It accounts for all that is anomalous in the history, and pushes aside the main and consistent affirmation of all our authorities, that from the earliest days the tribe of Levi had a special connection with sacred things and a special position in Israel. To what straits its advocates are reduced may be seen in the fact that Wellhausen has to declare that there were two tribes of Levi, one purely secular that was all but destroyed in an attack upon Shechem, and which afterwards disappeared, and a later ecclesiastical and somewhat factitious tribe, or caste, which "towards the end of the monarchy arose out of the separate priestly families of Judah."[87] A more improbable suggestion than that can hardly be conceived.

But historical analogy, the favourite weapon of these very critics, also condemns it. Let us look at the growth of the priesthood in other ancient nations. In small and isolated communities the head of the household was generally the family priest, and in all probability this was the case in the various separate tribes of which Israel was composed; at least it was so in the households of the patriarchs. But, in communities formed by amalgamation of different tribes—and according to modern ideas Israel was so formed—there was almost always superinduced upon that more primitive state of things another and different arrangement. In antiquity no bond could hold together tribes or families conscious of different descent, save the bond of religion. Consequently, whenever such an amalgamation took place, the very first thing which had to be done was to establish religious rites common to the whole new community, which of course were not the care of the heads of households as such. Each separate section of the composite body kept up, no doubt, the family rites; but there had to be a common worship, and of course a special priesthood, for the new community. This is sufficiently attested for the Greeks and Romans by De Coulanges, who in his La Cité Antique gathers together such a mass of authorities in regard to this matter that few will be inclined to dispute his conclusion. On page 146 he says: "Several tribes might unite, on condition that the worship of each was respected. When such an alliance was entered into, the city or state came into existence. It is of little importance to inquire into the causes which induced several tribes to unite; what is certain is that the bond of the new association was again a religion. The tribes which grouped themselves to form a state never failed to light a sacred fire, and to set up a common religion." But the family and tribal rites continued to exist as sacra privata, just as the central government dominated but did not destroy the family and tribal governments.[88]

It may be objected that these customs are proved only for the Aryan races, and that, though proved for them, they form no valid analogy for Semitic peoples. But besides the fact that part of the statements we have quoted are obviously true of Israel, we have a guarantee that the principle enunciated is also valid for it. The whole process traced in the religious progress of the Aryan nations is based upon the worship of ancestors. Now one of the critical discoveries is that ancestor-worship was a part of the religion of the tribes which afterwards united to form the Israelite nation. Some, like Stade, tell us that that was the early religion of Israel itself. In that form the theory is, I think, to be rejected; but there would seem to be little doubt that, before the birth of the nation, ancestor-worship was much practised by the Hebrew tribes. If so, we may quite safely take over the analogy we have established, and believe that when Moses united the tribes into a nation, the religion of Yahweh was the absolutely necessary connecting link which bound them together. For though the tribes were related, and are represented as the descendants of Abraham, they must have varied considerably from each other in religious beliefs and usages. By Moses these variations were extinguished, as far as that was possible, by the establishment of an exclusive Yahweh-worship as the national cult; and to carry on this, not the heads of households, but a priesthood that represented the nation, must have been selected. But if so, who would most naturally be selected for this duty? A sentence from De Coulanges will show that in this case the tribe of Levi would almost necessarily be chosen. Speaking of cases in which a composite state relieved itself of the trouble of inventing a new worship by adopting the special god of one of the component tribes, he says: "But when a family consented to share its god in this fashion it reserved for itself at least the priesthood." Now if that was the case in Israel, the priesthood of the tribe of Levi would at once become a necessity. Whether Yahweh had been ever known to the other tribes or not, there can be little doubt that the knowledge of Him which made them a nation and started them on their unique career of spiritual discovery came from the Mosaic tribe, and family.

The God whom the family worshipped became the God of the confederacy, and they would be the natural guardians of His sanctuary. This would not in the least involve special sanctity and meekness on the part of the tribe, as some insist. They would remain a tribe, like the others; but their leading men would discharge the functions of priests for the confederated nation. It is difficult, indeed, to see why any one else should have been thought of: most likely the arrangement was made as a thing of course.

But if there was such a common worship, there must have been a sanctuary for it, and at it the Levitic priests must have discharged their functions. Now though the Tabernacle, as P knows it, is not spoken of either in JE or in Deuteronomy, a "tent of meeting" at which Jehovah revealed Himself to Moses and to which the people went to seek Yahweh (Exod. xxxiii. 7 ff.) is known to all our authorities. Further, Wellhausen himself says, "If Moses did anything at all he certainly founded the sanctuary at Qadesh and the Torah there, which the priests of the ark carried on after him," so that even he recognises the necessity we have pointed out. From the days of Moses onwards, therefore, there must have been special priests of Yahweh, a special Yahwistic sanctuary, ritual with a special sacrifice presented to Yahweh, and lastly a central oracle, which is precisely what the passages explained away by Wellhausen assert. But of course at that early time, even if the ultimate purpose was to have an exclusively Levitical priesthood, concessions to the old state of things would have to be made. The Passover was left in the hands of the household priest, and in other ways probably he would be considered. The old order would insist on surviving, and the rigour of the later arrangements cannot then have been attained. In other respects we know that it was so; and we may well believe that the priesthood of the individual householder and of the rulers was tolerated, and as far as possible regulated, so as to offer no public scandal to the religion of Yahweh. So, among the Homeric Greeks special hereditary priesthoods coexisted with a political priesthood of the head of the State, and with the household priesthood.[89]
