These are the Levites who started to work. From the Kohathite family there were Mahath son of Amasai and Joel son of Azariah. From the Merarite family there were Kish son of Abdi and Azariah son of Jehallelel. From the Gershonite family there were Joah son of Zimmah and Eden son of Joah.
Korah, Dathan, Abiram, and On turned against Moses. (Korah was the son of Izhar, the son of Kohath, the son of Levi; Dathan and Abiram were brothers, the sons of Eliab; and On was the son of Peleth; Dathan, Abiram, and On were from the tribe of Reuben.)
The tribe of Levi was also counted. These were the family groups of Levi: From Gershon came the Gershonite family group; from Kohath came the Kohathite family group; from Merari came the Merarite family group.
The Kohath family groups were part of the tribe of Levi. Some of the Levites in the Kohath family groups were from the family of Aaron the priest. To these Levites were given thirteen towns in the areas of Judah, Simeon, and Benjamin.
