Take the sum of the sons of Kohath from among the sons of Levi, by their families, by their fathers' houses,
And the sons of Kohath by their families; Amram, and Izhar, Hebron, and Uzziel.
And of Kohath was the family of the Amramites, and the family of the Izharites, and the family of the Hebronites, and the family of the Uzzielites: these are the families of the Kohathites.
And the LORD spake unto Moses and unto Aaron, saying,
from thirty years old and upward even until fifty years old, all that enter upon the service, to do the work in the tent of meeting.
