Leviticus 16:15   “Then he shall kill the goat of the sin offering that is for the people, and bring his blood within the veil, and do with his blood as he did with the blood of the bull, and sprinkle it on the mercy seat and before the mercy seat. ¹⁶ He shall make atonement for the Holy Place, because of the uncleanness of the children of Israel, and because of their transgressions, even all their sins; and so he shall do for the Tent of Meeting that dwells with them in the middle of their uncleanness. ¹⁷ No one shall be in the Tent of Meeting when he enters to make atonement in the Holy Place, until he comes out, and has made atonement for himself and for his household, and for all the assembly of Israel.

Hebrews 9:7  but into the second the high priest alone, once in the year, not without blood, which he offers for himself, and for the errors of the people. ⁸ The Holy Spirit is indicating this, that the way into the Holy Place wasn’t yet revealed while the first tabernacle was still standing. ⁹ This is a symbol of the present age, where gifts and sacrifices are offered that are incapable, concerning the conscience, of making the worshiper perfect, ¹⁰ being only (with meats and drinks and various washings) fleshly ordinances, imposed until a time of reformation.

¹¹ But Christ having come as a high priest of the coming good things, through the greater and more perfect tabernacle, not made with hands, that is to say, not of this creation, ¹² nor yet through the blood of goats and calves, but through his own blood, entered in once for all into the Holy Place, having obtained eternal redemption. ¹³ For if the blood of goats and bulls, and the ashes of a heifer sprinkling those who have been defiled, sanctify to the cleanness of the flesh, ¹⁴ how much more will the blood of Christ, who through the eternal Spirit offered himself without defect to God, cleanse your conscience from dead works to serve the living God?
