Leviticus 16:18

After he had made atonement for the dwelling, Aaron was to expiate the altar in the court, by first of all putting some of the blood of the bullock and he-goat upon the horns of the altar, and then sprinkling it seven times with his finger, and thus cleansing and sanctifying it from the uncleannesses of the children of Israel. The application of blood to the horns of the altar was intended to expiate the sins of the priests as well as those of the nation; just as in the case of ordinary sin-offerings it expiated the sins of individual members of the nation (Lev 4:25, Lev 4:30, Lev 4:34), to which the priests also belonged; and the sevenfold sprinkling effected the purification of the place of sacrifice from the uncleannesses of the congregation. The meaning of the sprinkling of blood upon the capporeth and the horns of the two altars was the same as in the case of every sin-offering. The peculiar features in the expiatory ritual of the day of atonement were the following. In the first place, the blood of both sacrifices was taken not merely into the holy place, but into the most holy, and sprinkled directly upon the throne of God. This was done to show that the true atonement could only take place before the throne of God Himself, and that the sinner was only then truly reconciled to God, and placed in the full and living fellowship of peace with God, when he could come directly to the throne of God, and not merely to the place where, although the Lord indeed manifested His grace to him, He was still separated from him by a curtain. In this respect, therefore, the bringing of the blood of atonement into the most holy place had a prophetic signification, and was a predictive sign that the curtain, which then separated Israel from its God, would one day be removed, and th…

In this chapter we have the institution of the annual solemnity of the day of atonement, or expiation, which had as much gospel in it as perhaps any of the appointments of the ceremonial law, as appears by the reference the apostle makes to it, Heb 9:7, etc. We had before divers laws concerning sin-offerings for particular persons, and to be offered upon particular occasions; but this is concerning the stated sacrifice, in which the whole nation was interested. The whole service of the day is committed to the high priest. I. He must never come into the most holy place but upon this day (Lev 16:1, Lev 16:2). II. He must come dressed in linen garments (Lev 16:4). III. He must bring a sin-offering and a burnt-offering for himself (Lev 16:3), offer his sin-offering (Lev 16:6-11), then go within the veil with some of the blood of his sin-offering, burn incense, and sprinkle the blood before the mercy-seat (Lev 16:12-14). IV. Two goats must be provided for the people, lots cast upon them, and, 1. One of them must be a sin-offering for the people (Lev 16:5, Lev 16:7-9), and the blood of it must be sprinkled before the mercy-seat (Lev 16:15-17), and then some of the blood of both the sin-offerings must be sprinkled upon the altar (Lev 16:18, Lev 16:19). 2. The other must be a scape-goat (Lev 16:10), the sins of Israel must be confessed over him, and then he must be sent away into the wilderness (Lev 16:20-22), and he that brought him away must be ceremonially unclean (Lev 16:26). V. The burnt-offerings were then to be offered, the fat of the sin-offerings burnt on the altar, and their flesh burnt without the camp (Lev 16:23-25, Lev 16:27, Lev 16:28). VI. The people were to observe the day religiously by a holy rest and holy mourning for sin; and this was to be a statute for eve…
