Leviticus 16:15 - Coke's Commentary on the Holy Bible

Then shall he kill the goat of the sin-offering— Having performed the ceremonies requisite for his own expiation and that of his family, he was to proceed, in the same manner, to make expiation for the sins of the whole people, whose transgressions in the foregoing year rendered their place of worship unfit for God's habitation; and, therefore, the victim's blood was offered by the priests, as a sign of their having forfeited their own blood or life, and as an atonement for them, through the blood of the great Mediator. All this, as the apostle to the Hebrews has set forth, served abundantly to shew the imperfection of the legal dispensation; see Hebrews, chap. 10: Note; 1. Our most solemn services need pardon; even our prayers and duties must be sprinkled with the blood of Jesus. 2. When Jesus gave himself for us, of the people there was none with him: the work was all his own, and to him be all the glory of it ascribed.
