Aaron, returning from the Most Holy, obtained some of the bull’s blood, entered this compartment with it, and spattered some of the blood with his finger seven times in front of the Ark cover on the E side. Thus was completed the atonement for the priesthood, which rendered the priests clean and able to mediate between Jehovah and his people.​—Le 16:14.

Aaron sacrificed the bull for the priests and the rest of the tribe of Levi, sprinkling its blood in the Most Holy. (Le 16:11, 14) Christ comparably presented the value of his human blood to God in heaven, where it could be applied to benefit those who would come to rule with him as priests and kings. (Re 14:1-4; 20:6)
