Numbers 4:33
This is the service of the families of the sons of Merari, according to all their service, in the tabernacle of the congregation, under the hand of Ithamar the son of Aaron the priest.
This is the service of the families of the sons of Merari,.... The Mahlites and Mushites, namely, the service before observed, the particulars of which are given:
according to all their service in the tabernacle of the congregation; agreeably to what was allotted to them in that part of the tabernacle they were concerned in:
under the hand of Ithamar the son of Aaron the priest; who had the oversight of these as well as of the Gershonites, as Eleazar had of the Kohathites; though as Eleazar was the chief of the tribe of Levi, it is thought that Ithamar acted under him, Numbers 3:32.
