Numbers 3:32
And Eleazar the son of Aaron the priest shall be chief over the chief of the Levites, and have the oversight of them that keep the charge of the sanctuary.
And Eleazar the son of Aaron the priest,.... Who was of the first of these families, the Amramites:
shall be chief over the chief of the Levites; over the three chiefs of the three houses of the Levites, who were Eliasaph the son of Lael, the chief of the Gershonites; and Elizaphan the son of Uzziel, the chief of the Kohathites; and Zuriel the son of Abihail, the chief of the Merarites:
and have the oversight of them that keep the charge of the sanctuary; the Kohathites, who had the care of the things belonging to the holy and most holy places; and these were particularly under the inspection of Eleazar, because they were things the priests had a, special concern in; see Numbers 4:32.
