Matthew Poole and continuators on 1 Chronicles 23:13

13 The sons of Amram; Aaron and Moses: and Aaron was separated, that he should sanctifie the most holy things , he and his sons for ever, to burn incense before the LORD, to minister unto him, and to bless in his name for ever.

Not positively; for so he could not sanctifie them, they being already sanctified by God in the highest Degree; but negatively, i. e. that he might keep them from Pollution: For these most holy things were polluted when they were touched by any other persons.

Not onely his eldest Sons the High-priests successively, but all his Posterity or all the Priests; for the Works here following were not peculiar to the High-priest, but common to all the Priests, who might all burn Incense, 2 Chron. 29. 11. Luke 1. 9. and to minister in the Temple, and to bless the People in Gods Name, Numb. 6. 23. Deut. 10. 8.
