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.
