And Aaron lifted up his hand toward the people, and blessed them, and came down from offering of the sin offering, and the burnt offering, and peace offerings. And Aaron lifted up his hand toward the people, and blessed them - On lifting up the hands in prayer, see Exodus 9:29. The form of the blessing we have in Numbers 6:23, etc.: "The Lord bless thee and keep thee! The Lord make his face shine upon thee, and be gracious unto thee! The Lord lift up his countenance upon thee, and give thee peace!" See the notes on these passages Exodus 9:29 (note), and Numbers 6:23 (note).
And came down from offering of the sin-offering, etc. - A sin-offering, a burnt-offering, a meat-offering, and peace-offerings, were made to God that his glory might appear to the whole congregation. This was the end of all sacrifice and religious service; not to confer any obligation on God, but to make an atonement for sin, and to engage him to dwell among and influence his worshippers.
