*Take a census of the sons of Gershon also, by their fathers' houses, by their families;
These are the names of the sons of Gershon by their families: Livni and Shim`i.
Of Gershon was the family of the Livni, and the family of the Shim`i: these are the families of the Gershoni.
The prince of the fathers' house of the Gershoni shall be Elyasaf the son of La'el.
The LORD spoke to Moshe, saying,
from thirty years old and upward until fifty years old shall you number them; all who enter in to wait on the service, to do the work in the Tent of Meeting.
