8 and Aaron shall cast lots on the two goats, one lot for the Lord and the other lot for Azazel. 9 Aaron shall present the goat on which the lot fell for the Lord, and offer it as a sin offering; 10 but the goat on which the lot fell for Azazel shall be presented alive before the Lord to make atonement over it, that it may be sent away into the wilderness to Azazel.
Matthew Henry's Commentary on Leviticus 16:8-10
Commentary on Leviticus 16:1-14
(Read Leviticus 16:1-14)
Without entering into particulars of the sacrifices on the great day of atonement, we may notice that it was to be a statute for ever, till that dispensation be at an end. As long as we are continually sinning, we continually need the atonement. The law of afflicting our souls for sin, is a statue which will continue in force till we arrive where all tears, even those of repentance, will be wiped from our eyes. The apostle observes it as a proof that the sacrifices could not take away sin, and cleanse the conscience from it, that in them there was a remembrance made of sin every year, upon the day of atonement, Hebrews 10:1,3. The repeating the sacrifices, showed there was in them but a feeble effort toward making atonement; this could be done only by offering up the body of Christ once for all; and that sacrifice needed not to be repeated.
