'Unwalled' in the Bible

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

Therefore the Jews of the villages, who live in the unwalled towns, make the fourteenth day of the month Adar a day of gladness and feasting, a good day, and a day of sending presents of food to one another.

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