“Take a census of the sons of Kohath from amongst the sons of Levi, by their families, by their fathers’ houses,
The sons of Kohath by their families: Amram, Izhar, Hebron, and Uzziel.
Of Kohath was the family of the Amramites, the family of the Izharites, the family of the Hebronites, and the family of the Uzzielites. These are the families of the Kohathites.
The LORD spoke to Moses and to Aaron, saying,
from thirty years old and upward even until fifty years old, all who enter into the service to do the work in the Tent of Meeting.
