Aaron’s sons - The common priests. Nothing is said here, or in Exodus 29:7-9, of the anointing of the common priests, though it is expressly commanded in Exodus 28:41; Exodus 40:15, and is evidently implied as a fact in Leviticus 7:36; Leviticus 10:7; Numbers 3:3. It would seem that the anointing of the common priests consisted in some rite common to them and the high priest Exodus 40:15, and this was the sprinkling mentioned in Leviticus 8:30. Compare further Leviticus 10:7 with Leviticus 21:12.
