Exodus 30:10

10 aAaron shall make atonement on its horns once a year. With the blood of the bsin offering of atonement he shall make atonement for it once in the year throughout your generations. It is most holy to the Lord.”

Leviticus 16:2-20

2and the Lord said to Moses, “Tell Aaron your brother not to ccome at any time into the Holy Place inside the veil, before the mercy seat that is on the ark, so that he may not die. For dI will appear in the cloud over the mercy seat. 3But in this way Aaron shall come into the Holy Place: ewith a bull from the herd for a sin offering and fa ram for a burnt offering. 4He shall put on gthe holy linen coat and shall have the linen undergarment on his body, and he shall tie the linen sash around his waist, and wear the linen turban; these are the holy garments. hHe shall bathe his body in water and then put them on. 5And he shall take from ithe congregation of the people of Israel two male goats for a sin offering, and one ram for a burnt offering.

6Aaron shall joffer the bull as a sin offering for himself and shall kmake atonement for himself and for his house. 7Then he shall take the two goats and set them before the Lord at the entrance of the tent of meeting. 8And Aaron shall cast lots over the two goats, one lot for the Lord and the other lot for lAzazel.
The meaning of  Azazel is uncertain; possibly the name of a place or a demon, traditionally a scapegoat; also verses 10, 26
9And Aaron shall present the goat on which the lot fell for the Lord and use it as a sin offering, 10but the goat on which the lot fell for nAzazel shall be presented alive before the Lord to make atonement over it, that it may be sent away into the wilderness to oAzazel.

11Aaron shall present pthe bull as a sin offering for himself, and shall make atonement for himself and for his house. He shall kill the bull as a sin offering for himself. 12And he shall take qa censer full of coals of fire from the altar before the Lord, and two handfuls of sweet incense beaten small, and he shall bring it inside the veil 13 rand put the incense on the fire before the Lord, that the cloud of the incense may cover sthe mercy seat that is over the testimony, so that he does not die. 14And the shall take some of the blood of the bull and sprinkle it with his finger on the front of the mercy seat on the east side, and in front of the mercy seat he shall sprinkle some of the blood with his finger seven times.

15 u“Then he shall kill the goat of the sin offering that is for the people and bring its blood vinside the veil and do with its blood as he did with the blood of the bull, sprinkling it over the mercy seat and in front of the mercy seat. 16Thus he shall wmake atonement for the Holy Place, because of the uncleannesses of the people of Israel and because of their transgressions, all their sins. And so he shall do for the tent of meeting, which dwells with them in the midst of their uncleannesses. 17 xNo one may be in the tent of meeting from the time he enters to make atonement in the Holy Place until he comes out and has made atonement for himself and for his house and for all the assembly of Israel. 18Then he shall go out to the altar that is ybefore the Lord and zmake atonement for it, and shall take some of the blood of the bull and some of the blood of the goat, and put it on the horns of the altar all around. 19And he shall sprinkle some of the blood on it with his finger seven times, and cleanse it and consecrate it from the uncleannesses of the people of Israel.

20“And when he has made an end of aaatoning for the Holy Place and the tent of meeting and the altar, he shall present the live goat.

Leviticus 16:34

34And this shall be a statute forever for you, that atonement may be made for the people of Israel abonce in the year because of all their sins.” And Aaron
Hebrew he
did as the Lord commanded Moses.

Hebrews 9:24-25

24For Christ has entered, not into holy places admade with hands, which are copies of the true things, but into heaven itself, now to appear in the presence of God aeon our behalf. 25Nor was it to offer himself repeatedly, as afthe high priest enters agthe holy places every year with blood not his own,
