In Deuteronomy, on the contrary, the priests are very prominent; they are called, however, the Levitical priests, or priests simply, but never sons of Aaron. The whole tribe of Levi is regarded as priestly in some sense. They constitute, in fact, a clerical order, though there are clear indications of ranks, of men being assigned to special duties. Curiously enough, the tribe thus highly honoured is spoken of as being notoriously and all but universally poor. No sacrifice can legitimately be offered without them; and, though the question of the place of sacrifice has not yet been finally settled, the position of the Levitical priests as sacrificers is so entirely established that it is regarded as needing neither assertion nor justification. Nay, in one passage, Deut. x. 6--which there is no valid reason, except the wish to get rid of its contents, for supposing to belong to another authority than D[13]--the hereditary succession to the chief place among the priesthood is assigned to the family of Aaron. In xviii. 5 also the hereditary character of the priesthood is asserted in the words, "For Yahweh thy God hath chosen him--_i.e._ the priest--out of all thy tribes, to stand to minister in the name of Yahweh, _him and his sons for ever_." As for the body of the Levites, their position is somewhat ill-defined. On the authority of xviii. 6 ff. many claim that at the date of Deuteronomy every Levite was, at least potentially, a priest, that in fact Levite and priest were synonymous. But, as will appear in the exposition of the verses referred to, that is a very questionable proposition. Nevertheless it cannot be denied that in Deuteronomy the line between priests and Levites is a very indistinct one; there is _prima facie_ reason to believe that it could be passed, and the gap between the two is certainly not nearly so wide as it appears to be in the undeniably post-exilic literature.

In the Priest Codex again, the priesthood is confined exclusively to the house of Aaron, with the high priest at their head. The Levites have no possible way of entrance into the priesthood. They are Yahweh's gift to the priests, and are confined most strictly to the duty of waiting upon these in the ministration of the Sanctuary. They have none but the most subordinate share in the sacrifices; they are shut out from the holy places of the Tabernacle; and they have assigned to them cities in which they may dwell together when they are not on duty at the Sanctuary. There is no word there of Levites being poor, and altogether the position of the tribe is, through the priests, much more dignified and prosperous in a worldly sense than we found it to be in Deuteronomy.
