The surviving sons of Aaron, Eleazar and Ithamar, were anointed and "consecrated to minister in the priest's office." The form of designation is indicated by the expression, "whose hand he filled to exercise priesthood." This has been explained as referring to a portion of the ceremony described in Lev. viii. 26 f. "And out of the basket of unleavened bread, that was before the Lord, he took one unleavened cake, and one cake of oiled bread, and one wafer, and placed them on the fat, and upon the right thigh: and he put the whole upon the hands of Aaron, and upon the hands of his sons, and waved them for a wave offering before the Lord." The explanation is scarcely satisfactory. In the long ceremony of consecration this incident was not the only one to which the expression "filling the hand" was applied; and something simpler must be found as the source of an idiomatic phrase. To fill the hand would naturally mean to pay or hire, and we seem to be pointed to the time when for the patriarchal priesthood there was substituted one that was official, supported by the community. In Exod. xxviii. 41 and in Lev. viii. 33, the expression in question is used in a general sense incompatible with its reference to any particular portion of the ceremony of consecration. It is also used in Judges xvii., where to all appearance the consecration of Micah's Levite implied little else than the first payment on account of a stipulated hire. The phrase, then, appears to be a mark of history, and carries the mind back to the simple origin of the priestly office. Eleazar and Ithamar "ministered in the priest's office in the presence of Aaron their father." So far as the narrative of the Pentateuch gives information, there were originally, and during the whole of the wilderness journey, no other priests than Aaron and his sons. Nadab and Abihu having died, there remained but the two besides their father. Phinehas the son of Eleazar appears in the history, but is not called a priest, nor has he any priestly functions. What he does is indeed quite apart from the holy office. And this early restriction of the number is not only in favour of the Pentateuchal history, but partly explains the fact that in Deuteronomy the priests and Levites are apparently identified. Taking at their very heaviest the duties specially laid on the priests, much must have fallen to the share of their assistants, who had their own consecration as ministers of the sanctuary. It is certain that members of the Levitical families were in course of time admitted to the full status of priests.
