Joshua 21:26

All the cities were ten, with their suburbs ,.... Four out of Ephraim, four out of Dan, and two out of the half tribe of Manasseh: which were

for the families of the children of Kohath that remained : who were of the other branch of the Kohathites, and who did not descend from Aaron, and were only Levites, and not priests; See Gill on Joshua 21:20 .
