“Take a census of the sons of Kohath from among the sons of Levi, by their families (clans), by their fathers’ households,
and the [four] sons of Kohath by their families: Amram, Izhar, Hebron, and Uzziel;
Of Kohath were the families of the Amramites, the Izharites, the Hebronites, and the Uzzielites; these are the families of the Kohathites.
Then the Lord spoke to Moses and Aaron, saying,
from thirty years old and upward, even to fifty years old, all who enter the service to do the work in the Tent of Meeting (tabernacle).
