Leviticus 16:14 And he shall take of the blood of the bullock, and sprinkle it with his finger upon the mercy seat eastward; and before the mercy seat shall he sprinkle of the blood with his finger seven times.
[Patriarchs & Prophets pp 355>356] The priest was to bring his blood within the veil, and sprinkle it upon the mercy seat. “And he shall make an atonement for the holy place, because of the uncleanness of the children of Israel, and because of their transgressions in all their sins; and so shall he do for the tabernacle of the congregation, that remaineth among them in the midst of their uncleanness.” “And Aaron shall lay both his hands upon the head of the live goat, and confess over him all the iniquities of the children of Israel, and all their transgressions in all their sins, putting them upon the head of the goat, and shall send him away by the hand of a fit man into the wilderness: and the goat shall bear upon him all their iniquities into a land not inhabited.”
Not until the goat had been thus sent away did the people regard themselves as freed from the burden of their sins. Every man was to afflict his soul while the work of atonement was going forward. All business was laid aside, and the whole congregation of Israel spent the day in solemn humiliation before God, with prayer, fasting, and deep searching of heart. Important truths concerning the atonement were taught the people by this yearly service. In the sin offerings presented during the year, a substitute had been accepted in the sinner's stead; but the blood of the victim had not made full atonement for the sin. It had only provided a means by which the sin was transferred to the sanctuary.
By the offering of blood, the sinner acknowledged the authority of the law, confessed the guilt of his transgression, and expressed his faith in Him who was to take away the sin of the world; but he was not entirely released from the condemnation of the law. On the Day of Atonement the high priest, having taken an offering for the congregation, went into the most holy place with the blood and sprinkled it upon the mercy seat, above the tables of the law. Thus the claims of the law, which demanded the life of the sinner, were satisfied.
Leviticus 16:16 And he shall make an atonement for the holy place, because of the uncleanness of the children of Israel, and because of their transgressions in all their sins: and so shall he do for the tabernacle of the congregation, that remaineth among them in the midst of their uncleanness.
May God add His blessing to the study of His word. "Good night" and God bless!
