This is the service of the clans of the sons of Merari, the whole of their service in the tent of meeting, under the direction of Ithamar the son of Aaron the priest.” 34
And Moses and Aaron and the chiefs of the congregation listed the sons of the Kohathites, by their clans and their fathers’ houses, 35
from thirty years old up to fifty years old, everyone who could come on duty, for service in the tent of meeting; 36
and those listed by clans were 2,750.
