Joshua 15:32

Twenty nine — Here are thirty seven or thirty eight cities named before; how then are they only reckoned twenty nine? There were only twenty nine of them, which either, properly belonged to Judah; the rest fell to Simeon's lot; or Were cities properly so called, that is, walled cities, or such as had villages under them, as it here follows; the rest being great, but unwalled towns, or such as had no villages under them.
