Aner and Bileam are mentioned in Chronicles, instead of Tanach
   and Gath-rimmon.  (1; Ch 6:70.)  Either the cities had at this
   time different names, or afterwards their names were changed;
   or the Levites, being by some means dispossessed of the cities
   first assigned them, received others from their brethren.  A
   careful examination of the marginal references will discover
   other variations of this kind, which may be accounted for in
   the same manner.

 * Tanach.
