'Cities of the Plain' in the Bible

So Abram lived in the land of Canaan, while Lot settled in the cities of the plain, setting up his tent in the vicinity of Sodom.

And so it was that, when God destroyed the cities of the plain, he remembered Abraham and brought Lot out from the midst of the destruction when he overthrew the cities where Lot had lived.

We took control of all the cities of the plain, all of Gilead and Bashan as far as Salecah and Edrei, cities of the kingdom of Og in Bashan.

all of the cities of the plain, the entire kingdom of King Sihon of the Amorites, who used to reign in Heshbon and whom Moses attacked, along with the chiefs of Midian, Evi, Rekem, Zur, Hur, and Reba, nobles of Sihon who lived in the land.
