1 Chronicles 23:13

The sons of Amram; Aaron and Moses,.... A son of Kohath, 1 Chronicles 23:2

and Aaron was separated; from the children of Israel, Exodus 28:1,

that he should sanctify the most holy things, he and his sons for ever; by an holy use of them, and keeping them from all unholy and profane uses; and this they were to do as long as the Aaronic priesthood lasted:

to burn incense before the Lord; in the holy place, on the altar of incense; which none but priests descended from Aaron might do:

to minister unto him; both at the altar of burnt offering and of incense; and the high priest in the holy of holies:

and to bless his name for ever, or "in his name"; that is, the people in his name; see Numbers 6:23.
