Yet all Aaron's sons had not been of this quiet disposition. Nadab and Abihu, the two eldest, had sinned presumptuously, and brought on themselves the doom of death. No fewer than five times is their fall referred to in the books of Leviticus and Numbers. Whatever that strange fire was which they put in their censers and used before the Lord, the judgment that befell them was signal and impressive. And here reference is made to the fact that they died without issue, as if to mark the barrenness of the sacrilegious. Did it not appear that inherent disqualification for the priesthood, the moral blindness or self-will which was shown in their presumptuous act, had been foreseen by God, who wrote them childless in His book? This race must not be continued. Israel must not begin with priests who desecrate the altar.
Whether the death of those two sons of Aaron came by an unexpected stroke, or was a doom inflicted after judgment in which their father had to acquiesce, the terrible event left a most effectual warning. The order appointed for the incense offering, and all other sacred duties, would thenceforth be rigidly observed. And the incident—revived continually for the priests when they studied the Law—must have had especial significance through their knowledge of the use and meaning of fire in idolatrous worship. The temptation was often felt, against which the fate of Nadab and Abihu set every priest on his guard, to mingle the supposed virtue of other religious symbols with the sanctities of Jehovah. Who can doubt that priests of Israel, secretly tempted by the rites of sun-worship, might have gone the length of carrying the fire of Baal into Jehovah's temple, if the memory of this doom had not held back the hand? Here also the degradation of the burnt offering by taking flame from a common fire was by implication forbidden. The source of that which is the symbol of Divine purity must be sacredly pure.
Those who minister in holy things have still a corresponding danger, and may find here a needed warning. The fervour shown in sacred worship and work must have an origin that is purely religious. He who pleads earnestly with God on behalf of men, or rises to impassioned appeal in beseeching men to repent, appearing as an ambassador of Christ urged by the love of souls, has to do not with symbols, but with truths, ideas, Divine mysteries infinitely more sacred than the incense and fire of Old Testament worship. For the Hebrew priest outward and formal consecration sufficed. For the minister of the New Testament, the purity must be of the heart and soul. Yet it is possible for the heat of alien zeal, of mere self-love or official ambition, to be carried into duties the most solemn that fall to the lot of man; and if it is not in the Spirit of God a preacher speaks or offers the sacrifice of thanksgiving, if some other inspiration makes him eloquent and gives his voice its tremulous notes, sin like that of Nadab and Abihu is committed, or rather a sin greater than theirs. With profound sorrow it must be confessed that the "strange fire" from idolatrous altars too often desecrates the service of God. Excitement is sought by those who minister in order that the temperament may be raised to the degree necessary for free and ardent speech; and it is not always of a purely religious kind. Those who hear may for a time be deceived by the pretence of unction, by dramatic tones, by alien fire. But the difference is felt when it cannot be defined; and on the spiritual life of the ministrant the effect is simply fatal.
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.
The direction is given in ver. 10, "Thou shalt appoint Aaron and his sons, and they shall keep their priesthood; and the stranger that cometh nigh shall be put to death." This is rigorously exclusive, and seems to contrast with the statements of Deuteronomy, "At that time the Lord separated the tribe of Levi to bear the ark of the covenant of the Lord, to stand before the Lord to minister unto Him and to bless in His name unto this day" (x. 8); and again, "The priests the Levites, even all the tribe of Levi, shall have no portion nor inheritance with Israel; they shall eat the offerings of the Lord made by fire, and His inheritance" (xviii. 1); and once more, "Moses wrote the law and delivered it unto the priests, the sons of Levi, which bore the ark of the covenant of the Lord, and unto all the elders of Israel" (xxxi. 9). Throughout Deuteronomy the priests are never called sons of Aaron, nor is Aaron called a priest. Whether the cause of this apparent discrepancy is that Deuteronomy regarded the arrangements for the priestly service in a different light, or that the distinction of priests from Levites fell into abeyance and was afterwards revived, the variation cannot be ignored. In the book of Joshua "the children of Aaron the priest" appear on a few occasions, and certain of the duties of high priest are ascribed to Eleazar. Yet even in Joshua the importance attached to the Aaronic house is far less than in Exodus, Leviticus, and Numbers; and the expression "the priests the Levites" occurs twice. If we regard the origin of the Aaronic priesthood as belonging to the Mosaic period, then the wars and disturbances of the settlement in Canaan must have entirely disorganised the system originally instituted. In the days of the judges there seems to have been no orderly observance of those laws which gave the priesthood importance. Scattered Levites had to do as they best could what was possible in the way of sacrifice and purification. And this confusion may have begun in the plain of Moab. The death of Aaron, the personal insignificance of his sons, and still more the death of Moses himself, would place the administration of religious as well as secular affairs on an entirely different footing. Memoranda preserved in Leviticus and Numbers may therefore be more ancient than those of Deuteronomy; and Deuteronomy, describing the state of things before the passage of Jordan, may in regard to the priesthood reflect the conditions of a new development, the course of which did not blend with the original design till after the captivity.
