The rituals that were performed by the Jewish high priests were only a model of what Jesus our high priest does in heaven.

Hebrews 8:1-6

8 The main point of all that I have written is that we have a Supreme Priest like that. He has sat down to rule [MTY] with God [EUP] at the place of greatest honor in heaven. 2 He ministers in the Most Holy Place, that is, in the true place of worship in heaven. That is a place that Moses’ tent represented. The Lord set up the true place of worship. No human set it up.

3 Every Supreme Priest was appointed {God appointed every Supreme Priest} to offer to God gifts and sacrifices for people who sinned. So, since Christ became a Supreme Priest, he also had to offer something. 4 Since there are already Jewish priests who offer gifts as God’s laws require, if Christ were now living on the earth, he would not be a Supreme Priest. 5 The Jewish priests perform rituals which are only a model [DOU] of what Christ would do in heaven [MTY]. What God told Moses when Moses was about to set up the tent for worshipping him supports the idea that those rituals were only a model. God said, “Be sure that you (sg) make everything according to the model that I showed you on Sinai Mountain!” 6 But now as it is, Christ ministers in a more excellent way than the Jewish priests do. Likewise, the new covenant that he established between God and people is better than the old one. When the new covenant was established {God established the new covenant}, he promised us better things than the laws that God gave Moses did.
