Chapter 26
56Their inheritance shall be divided according to lot between the larger and the smaller."
57This was the list of the Levites according to their clans: of Gershon, the clan of the Gershonites; of Kohath, the clan of the Kohathites; of Merari, the clan of the Merarites.
58These are the clans of Levi: the clan of the Libnites, the clan of the Hebronites, the clan of the Mahlites, the clan of the Mushites, the clan of the Korahites. And Kohath was the father of Amram.
