As the priests also formed part of the Kohathites, their chief is mentioned as well, viz., Eleazar the eldest son of Aaron the high priest, who was placed over the chiefs of the three Levitical families, and called פּקדּה, oversight of the keepers of the charge of the sanctuary," i.e., authority, superior, of the servants of the sanctuary.

The chief of the Levites - That is, over those three persons, who were each the chief of their several families, Numbers 3:24, Numbers 3:31, Numbers 3:34.
