'Unwalled' in the Bible

All of these cities were fortified with high walls, gates, and bars. Furthermore, there were very many unwalled regions.

The gold mice represented the number of all the Philistine towns belonging to the five lords, both fortified towns and unwalled villages. The large stone, beside which they put the Ark of the LORD, is a witness to this day in the field of Joshua of Beth-shemesh.

Therefore the Jewish people in the rural areas who live in unwalled towns make the fourteenth day of the month Adar a holiday for joy and feasting, and people send presents to one another.
