Numbers 26:57

And the sons of Levi according to their families; to Gedson, the family of the Gedsonites; to Caath, the family of the Caathites; to Merari, the family of the Merarites.

And these are they that were numbered of the Levites after their families: of Gershon, the family of the Gershonites: of Kohath, the family of the Kohathites: of Merari, the family of the Merarites.

These are those who were counted of the Levites after their families: of Gershon, the family of the Gershonites; of Kohath, the family of the Kohathites; of Merari, the family of the Merarites.
