1 Chronicles 23:13

That he should sanctify the most holy things; not positively, for so he could not sanctify 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. He and his sons; not only 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 Chronicles 29:11 Luke 1:9, and to minister in the temple, and to bless the people in God's name, Numbers 6:23 Deuteronomy 10:8.
