There was to be no one in the ohel moed when Aaron went into it to make expiation in the most holy place, until he came out (of the tabernacle) again; not because no one but the chief servant of Jehovah was worthy to be near or present either as spectator or assistant at this sacred act before Jehovah (Knobel), but because no unholy person was to defile by his presence the sanctuary, which had just been cleansed; just as no layman at all was allowed to enter the holy place, or could go with impunity into the presence of the holy God.
