So far then as departures from earlier custom can be shown in the sacrificial dues enjoined by the Priestly Code, they must not indeed be treated as purely local differences, but neither are they to be regarded as on the whole showing a serious raising of the tariff.  But in the Code the sacrificial dues are only a subordinate part of the income of the priests.  In Deuteronomy the priests are entirely thrown upon the sacrifices; they live upon them (xviii. 1) and upon invitations to the sacred banquets (xii.  I2, 18 seq.); if they are not exercising the priestly function they must starve (1Samuel ii. 36).  On the other hand, the Aaronidae of the Priestly Code do not need to sacrifice at all, and yet have means of support, for their chief revenue consists of the rich dues which must be paid them from the products of the soil.

V.I.2.  The dues falling to the priests according to the law were all originally offerings—­the regular offerings which had to be brought on the festivals; and these all originally were for sacred banquets, of which the priests received nothing more than the share which was generally customary.  This is true in the first instance of the male firstlings of cattle.  As we have seen in the chapter on the sacred feasts, these are sacrifices and sacrificial meals, alike in the Jehovistic legislation and in the Jehovistic narrative of the exodus and of Abel, as were all the offerings brought by private individuals in the olden time.  When in Exodus xxii. 29 it is said that they must be given to JEHOVAH, this does not mean that they must be given to THE PRIESTS; no such thing is anywhere said in thc Book of the Covenant.  Matters still stand on essentially the same footing in Deuteronomy also:  “THOU SHALT SANCTIFY THEM UNTO JEHOVAH; thou shalt not plough with the firstling of the bullock, nor shear the firstling of thy sheep; THOU SHALT EAT IT BEFORE JEHOVAH year by year in the place which He shall choose; and if there be any blemish therein, thou shalt not OFFER IT TO JEHOVAH THY GOD” (Deuteronomy xv. 19, 20).  To sanctify to Jehovah, to eat before Jehovah, to offer to Jehovah, are here three equivalent ideas.  If now, in Numbers xviii. 15 seq., every first birth is assigned without circumlocution to the priest, and a special paschal offering is appointed in addition, this can only be understood as the last phase in the development, partly because the idea of dues altogether is secondary to that of offerings, and partly because the immense augmentation in the income of the priests points to an increase of the hierocratic power.  Ezekiel does not yet reckon the firstlings among the revenues of the clergy (xliv. 28-3I); the praxis of Judaism, on the other hand, since Nehemiah x. 37, is regulated, as usual, in accordance with the norm of the Priestly Code.
