Charles Ellicott Commentary 1 Chronicles 6:70

"and out of the half-tribe of Manasseh, Aner with its suburbs, and Bileam with its suburbs, for the rest of the family of the sons of Kohath." — 1 Chronicles 6:70 (ASV)

Aner ... Bileam. —Joshua 21:25 reads, Taa-nach [see Joshua 17:11] and Gath-rimmon. The latter is a mere repetition from the preceding verse. Bileam is a man’s name, being the Hebrew spelling of Balaam. It should be Ibleam (Joshua 17:11). So the Septuagint Aner (Genesis 14:13) is also a man, one of Abraham’s allies. Taanach is probably right, the last three letters of the Hebrew word closely resembling those of Aner.

For the family. —Better, unto the family of the sons of Kohath who were left. This depends on the idea of giving (1 Chronicles 6:67). The phrase is a sort of subscription to the whole list of 1 Chronicles 6:67–70. For “family” the plural should be read, as in Joshua 21:26.
