“At the mouth of Aharon and his sons is all the service of the sons of the Gĕrshonites, all their burden and all their service. And you shall appoint to them all the duty of all their burden.
“This is the service of the clans of the sons of Gĕrshon in the Tent of Appointment. And let their duties be under the hand of Ithamar, son of Aharon the priest.
