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. * * * * *
