No 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.
Leviticus 16:17 ESV

No one but the High Priest can make the atonement of #yomkippur. Nobody else is even allowed in the Tent.

As Hebrews says, if Yeshua were on earth, he would not be qualified to offer any sacrifices in the Temple, because he is not a son of Aaron. However, the Aaronic High Priest is analogous to the Heavenly High Priest, Yeshua. He is the only one who can make atonement in the Most Holy Place in Heaven.
