Leviticus 9:1-24

Here we see the priests actually beginning their sacred work. After the gathering of the people, they stood in solemn silence in the presence of Jehovah. Aaron's first act was bringing the sin offering and the burnt offering for himself. He could not be the instrument of mediation between the people and God for worship save as he was brought into right relationship with God

The first acts of the priests on behalf of the people are now recorded. The offerings brought were presented: first the sin offering, then the burnt offering, then the meal offering, and, finally, the peace offering. The very order of procedure is a revelation of the fundamental principles on the life of worship.

His work completed in the outer court Aaron, accompanied by Moses, passed within the Tent. What took place there is not described. Coming forth again, Moses as representative of God and Aaron as mediating priest, blessed the people and immediately the glory of the Lord was manifested in the sight of the congregation. This a was followed by the prostration and worship of the gathered multitude.

Carefully observe this order. Sin put away, life and work devoted, communion made possible; then the priestly blessing, speaking of acceptance, followed by a second blessing, which declared the divine satisfaction as it was accompanied by the manifestation of glory, and so finally the full worship of the people.
