Double city, a town of Naphali, assigned to the Gershonite Levites, and one of the cities of refuge (Joshua 21:32). It was probably near the north-western shore of the Sea of Tiberias, identical with the ruined village el-Katanah.
Int. Standard Bible Encyclopedia
kar'-tan (qartan): A city in the territory of Naphtali, given to the Gershonite Levites (Joshua 21:32). It is called Kiriathaim in 1 Chronicles 6:76. Kartan may be a contraction of this. Cheyne (EB, under the word) suggests that both names may be corruptions from "Chinnereth." Neither is mentioned in Joshua 19:32, 38, in the list of Naphtalite cities, while Chinnereth is.
