Leviticus 16:29-34

Lev 16:29 “And it will be a permanent prescription to you that in the seventh month, on the tenth day of the month, you will discipline your souls and will do no work, either the native or the foreign guests who are temporary residents among you.
Lev 16:30 Because on this day will reconciliation be provided for you to cleanse you. You will be clean in Yahveh’s sight from all your mistakes.
Lev 16:31 It is a Sabbath of solemn rest to you, and you will discipline your souls; it is a permanent prescription.
Lev 16:32 And the priest who is anointed and consecrated as priest in his father’s place will provide reconciliation, wearing the holy linen garments.
Lev 16:33 He will provide reconciliation for the holy sanctuary, and he will provide reconciliation for the conference tent and for the altar, and he will provide reconciliation for the priests and for all the people of the collected assembly.
Lev 16:34 And this will be a permanent prescription for you, that reconciliation may be provided for the people of Israel once in the year because of all their mistakes.” And Aaron did as Yahveh commanded Moses.

priest in his father’s place

The LORD established a priestly dynasty, so that there would always be a son of Aaron serving and providing reconciliation for the nation on that special day. It was important that the ritual for that special day reflect the fact that the great high priest to come would be serving in his Father’s place. He would not be a son of Aaron, but the only Son of God. His ministry would not be in type and symbol, but eternal reality. His ministry would make null and void the ministry of the tabernacle or temple in the same way that the event prophesied makes null and void the prophecy.

LORD, thank you for the finished work of reconciliation, and our great high priest who performed it.
