'Unwalled' in the Bible

All these were cities fortified with high walls, gates, and bars; besides the unwalled towns a great many.

Therefore do the Jews of the villages, that dwell in the unwalled towns, make the fourteenth day of the month Adar a day of gladness and feasting, and a good day, and of sending portions one to another.

and thou shalt say, I will go up to the land of unwalled villages; I will go to them that are at rest, that dwell securely, all of them dwelling without walls, and having neither bars nor gates;
