Those that descended from him, though of the same tribe of Levi were all priests:

the daily sacrifice, and all the offerings of the people brought to them:

and on the altar of incense;
they burnt incense night and morning: and were appointed

for all the work of the place most holy;
such as were high priests of the line of Eleazar, whose work it was to go into the most holy place once a year:

to make atonement for all Israel, according to all that Moses the
servant of God commanded;
in ( Leviticus 16:1 ) which see; and on mention of this, a list of the high priests from Aaron, in the line of Eleazar, is given, to the times of Solomon, in the four following verses, just in the same order as in ( 1 Chronicles 6:4-8 ) .
