'Cities of the Plain' in the Bible

And when God destroyed the cities of the plain, it happened that God remembered Abraham, and sent Lot out of the midst of the overthrow, when He overthrew the cities in which Lot lived.

All the cities of the plain, and all Gilead, and all Bashan, and Salecah and Edrei, cities of the kingdom of Og in Bashan were taken.

and all the cities of the plain, and all the kingdom of Sihon king of the Amorites, who reigned in Heshbon (whom Moses struck with the rulers of Midian, Evi, and Rekem, and Zur, and Hur, and Reba, rulers of Sihon, the inhabitants of the land).
