(32) And Eleazar the son of Aaron the priest . . . --In virtue, as it should seem, of the descent of Moses and Aaron from Kohath, the Kohathites had the most honourable portion of the service of the Tabernacle assigned to them; and hence, as the priests belonged to the Amramites, one of the four families of the Kohathites, Eleazar, the eldest surviving son of Aaron, was chosen to have the oversight over the whole body of the Levites.

Verse 32. - Eleazar. The priests were themselves Kohathites, and therefore their chief is here mentioned as having the oversight over the other overseers - ipsos custodes custodiens.

3:14-39 The Levites were in three classes, according to the sons of Levi; Gershon, Kohath, and Merari; and these were subdivided into families. The posterity of Moses were not at all honoured or privileged, but stood upon the level with other Levites; thus it was plain, that Moses did not seek the advancement of his own family, or to secure any honours to it. The tribe of Levi was by much the least of all the tribes. God's chosen are but a little flock in comparison with the world.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.
