C. F. Keil and Franz Delitzsch on Joshua 21:20-25

Jos 21:20-25 Towns of the Levites. - Jos 21:20-26. The other Kohathites received four towns from the tribe of Ephraim (Jos 21:21, Jos 21:22), four from Dan (Jos 21:23, Jos 21:24), and two from the half tribe of Manasseh on this side of the Jordan (Jos 21:25). From Ephraim they received Shechem (see Jos 17:7), Gezer (Jos 10:33), Kibzaim - for which we find Jockmeam in 1Ch 6:68, possibly a different name for the same place, which has not yet been discovered - and Beth-horon, whether Upper or Lower is not stated (see Jos 10:10). From Dan they received Elthekeh and Gibbethon (Jos 19:44), Ajalon and Gath-rimmon (Jos 19:42, Jos 19:45). From half Manasseh they received Taanach (Jos 17:11; Jos 12:21) and Gath-rimmon - eye to the previous verse, for Bileam (1Ch 6:70), i.e., Jibleam (Jos 17:11).
