Aaron’s ordination has been completed. Going into the tent symbolizes his new role as the high priest. It may also demonstrate that the priesthood, rather than Moses alone, will now mediate between the Lord and his people. This is reinforced by the realization that this is the first time that Moses enters the holy place, though he had free communication with God outside the sanctuary. This marks a change in the way that the Lord deals with his people.
23 Moïse et Aaron entrèrent dans la tente d'assignation. Lorsqu'ils en sortirent, ils bénirent le peuple. Et la gloire de l'Eternel apparut à tout le peuple.
