“And the rest of the children of Kohath had by lot out of the families of the tribe of Ephraim, and out of the tribe of Dan, and out of the half tribe of Manasseh, ten cities.”
King James Version (KJV)
21:5 Children of Kohath - Who were of Aaron's family. Ephraim, Dan, and Manesseh - Which tribes are nearest to the three former, and so the Kohathites are placed next to their brethren the Aaronites. Ten cities - Fewer than they gave out of the three former tribes, because their inheritance was less than the former.
