"The atonement which the priest made for the people in connection with their daily ministration was different from that made on the tenth day of the seventh month.
In making the former, they went no further than in the Holy; but to make the latter they entered the Holy of Holies - the former was made for individual cases, the latter for the whole nation of Israel collectively - the former was made for the forgiveness of sins, the latter for blotting them out - the former could be made at any time, the latter only on the tenth day of the seventh month. Hence the former may be called the daily atonement and the latter the yearly.
It should be distinctly remembered that the priest did not begin his duties till he obtained the blood of the victim, and that they were all performed in the court (the enclosure of the Sanctuary), and that the atonement thus made was only for the forgiveness of sins.
These points are expressly taught in this chapter and the following one on the trespass-offering. Here is an atonement, to make which, the priests only entered the Holy, and to make it they could enter that apartment "always" or "daily".
"But into the second (the Holy of Holies) went the high priest alone once every year, not without blood, which he offered for himself, and for the errors of the people," (Laos, nation).
"And he shall go out (of the Holy of Holies) unto the altar that is before the Lord (in the Holy) and make an atonement for it; and shall take of the blood (for himself), and of the blood of the goat (for the people), and put it upon the horns of the altar round about. And he shall sprinkle of the blood upon it with his finger seven times, and cleanse it, and hallow it from the uncleanness of the children of Israel," verses 18, 19.
The holy place within the veil contained the ark of the covenant, covered with the mercy-seat, overshadowed by the cherubims, between which the Lord dwelt in the cloud of divine glory.
Q: Who would think of calling such a place unclean?
---Yet the Lord provided at the time, yea, before it was built, that it should be annually cleansed. It was by blood, and not by fire, that this Sanctuary, which was a type of the new covenant Sanctuary was cleansed."
