The sons of Amram; Aaron and Moses
 A son of Kohath, ( 1 Chronicles 23:2 ) ( Exodus 6:20 ) 
 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 6:23-27 ) .
