But, meeting such objectors on their own ground, we need not go into the matter further than to refer to the high authority of Dillmann, who declares this theory of the post-exilian origin of this institution to be "absolutely incredible;" and in reply to the objection that the day is not alluded to in the whole Old Testament history, justly adds that this argument from silence would equally forbid us to assign the origin of the ordinance to the days of the return from Babylon, or any of the pre-Christian centuries! for "one would then have to maintain that the festival first arose in the first Christian century; since only out of that age do we first have any explicit testimonies concerning it."[20]
Again, the first verse of the chapter gives as the occasion of the promulgation of this law, "the death of the two sons of Aaron," Nadab and Abihu, "when they drew near before the Lord and died;" a historical note which is perfectly natural if we have here a narrative dating from Mosaic days, but which seems most objectless and unlikely to have been entered, if the law were a late invention of rabbinical forgers. On that occasion it was, as we read (v. 2), that "the Lord said unto Moses, Speak unto Aaron thy brother, that he come not at all times into the holy place within the veil, before the mercy-seat which is upon the ark; that he die not: for I will appear in the cloud upon the mercy-seat."
Into this place of Jehovah's most immediate earthly manifestation, even Aaron is to come only once a year, and then only with atoning blood, as hereinafter prescribed.
The object of the whole service of this day is represented as atonement; expiation of sin, in the highest and fullest sense then possible. It is said to be appointed to make atonement for Aaron and for his house (ver. 6), for the holy place, and for the tent of meeting (vv. 15-17); for the altar of burnt-offering in the outer court (vv. 18, 19); and for all the congregation of Israel (vv. 20-22, 33); and this, not merely for such sins of ignorance as had been afterward recognised and acknowledged in the ordinary sin-offerings of each day, but for "all the iniquities of the children of Israel, and all their transgressions, even all their sins:" even such as were still unknown to all but God (ver. 21). The fact of such an ordinance for such a purpose taught a most impressive lesson of the holiness of God and the sinfulness of man, on the one hand, and, on the other, the utter insufficiency of the daily offerings to cleanse from all sin. Day by day these had been offered in each year; and yet, as we read (Heb. ix. 8, 9), the Holy Ghost this signified by this ordinance, "that the way into the holy place hath not yet been made manifest;" it was "a parable for the time now present;" teaching that the temple sacrifices of Judaism could not "as touching the conscience, make the worshipper perfect" (Heb. ix. 9). We may well reverse the judgment of the critics, and say—not that the deepened sense of sin in Israel was the cause of the day of atonement; but rather, that the solemn observances of this day, under God, were made for many in Israel a most effective means to deepen the conviction of sin.
The time which was ordained for this annual observance is significant—the tenth day of the seventh month. It was appointed for the seventh month, as the sabbatic month, in which all the related ideas of rest in God and with God, in the enjoyment of the blessings of a now complete redemption, received in the great feast of tabernacles their fullest expression. It was therefore appointed for that month, and for a day which shortly preceded this greatest of the annual feasts, to signify in type the profound and most vital truth, that the full joy of the sabbatic rest of man with God, and the ingathering of the fruits of complete redemption, is only possible upon condition of repentance and the fullest possible expiation for sin. It was appointed for the tenth day of this month, no doubt, because in the Scripture symbolism the number ten is the symbol of completeness; and was fitly thus connected with a service which signified expiation completed for the sins of the year.
The observances appointed for the day had regard, first, to the people, and, secondly, to the tabernacle service. As for the former, it was commanded (ver. 29) that they should "do no manner of work," observing the day as a Sabbath Sabbathon, "a high Sabbath," or "Sabbath of solemn rest" (ver. 31); and, secondly, that they should "afflict their souls" (ver. 31), namely, by solemn fasting, in visible sign of sorrow and humiliation for sin. By which it was most distinctly taught, that howsoever complete atonement may be, and howsoever, in making that atonement through a sacrificial victim, the sinner himself have no part, yet apart from his personal repentance for his sins, that atonement shall profit him nothing; nay, it was declared (xxiii. 29), that if any man should fail on this point, God would cut him off from his people. The law abides as regards the greater sacrifice of Christ; except we repent, we shall, even because of that sacrifice, only the more terribly perish; because not even this supreme exhibition of the holy love and justice of God has moved us to renounce sin.
As regards the tabernacle service for the day, the order was as follows. First, as most distinctive of the ritual of the day, only the high-priest could officiate. The other priests, who, on other occasions, served continually in the holy place, must on this day, during these ceremonies, leave it to him alone; taking their place, themselves as sinners for whom also atonement was to be made, with the sinful congregation of their brethren. For it was ordered (ver. 17): "There shall be no man in the tent of meeting when the high priest goeth in to make atonement in the holy place, until he come out," and the work of atonement be completed.
And the high priest could himself officiate only after certain significant preparations. First (ver. 4), he must "bathe in water" his whole person. The word used in the original is different from that which is used of the partial washings in connection with the daily ceremonial cleansings; and, most suggestively, the same complete washing is required as that which was ordered in the law for the consecration of the priesthood, and for cleansing from leprosy and other specific defilements. Thus was expressed, in the clearest manner possible, the thought, that the high priest, who shall be permitted to draw near to God in the holiest place, and there prevail with Him, must himself be wholly pure and clean.
Then, having bathed, he must robe himself in a special manner for the service of this day. He must lay aside the bright-coloured "garments for glory and beauty" which he wore on all other occasions, and put on, instead, a vesture of pure, unadorned white, like that of the ordinary priest; excepting only that for him, on this day, unlike them, the girdle also must be white. By this substitution of these garments for his ordinary brilliant robes was signified, not merely the absolute purity which the white linen symbolised, but especially also, by the absence of adornment, humiliation for sin. On this day he was thus made in outward appearance essentially like unto the other members of his house, for whose sin, together with his own, he was to make atonement.
