Joshua 19:7

‘ Ain, Rimmon and Ether and Ashan. Four cities with their villages.’

For the first two see Joshua 15:32 and 1 Chronicles 4:32. Ether and Ashan were in the Shephelah (Joshua 15:42).

LXX here combines Ain and Rimmon as one city and includes a further city Tochen (1 Chronicles 4:32), but in 1 Chronicles 4:32 LXX keeps Ain and Rimmon as separate ‘cities’. This suggests that the Hebrew text is correct.
