Leviticus 16:17

17. There shall be no man in the tabernacle The entire tabernacle must be vacant. The priests must leave their place and mingle with the Levites on guard around the sacred abode of Jehovah. The penitent people stand in silence and awe while their solitary representative, with trembling, approaches the presence of the holy God. How strikingly this prefigures the fact that there is but one Mediator, the man Jesus Christ. He must ever be solitary in his office. No virgin mother, no saint, no angel can be associated with him in making his atonement and in pleading its merits on high. To thrust an imaginary associate into the office of Intercessor, where Jesus stands alone, is to degrade and vilify him. Hebrews 1:3; Hebrews 9:7. See concluding note, (6.)

For all the congregation Every penitent Israelite had a share in the benefits of that atonement, as every penitent believer in Jesus Christ receives pardoning grace through his atoning blood. The conditional repentance, though not expressed, is evidently implied; for the notion that the mere mechanical performance of the high priest, irrespective of the state of heart of the sinner, resulted in a reconciliation, is even in the Talmud itself mentioned only to be forthwith rejected. The universality of the atonement is here clearly fore-shadowed.
