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, Heb 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.

That plain dress was more in harmony with a season of humiliation (as well as lighter and more convenient for the duties which on that occasion he had singly to perform) than the gorgeous robes of the pontificate. It showed that when all appeared as sinners, the highest and lowest were then on a level, and that there is no distinction of persons with God [Ac 10:34].
