Boyd’s Bible Dictionary:
(walled). A city six miles S. E. of Sea of Galilee. Jesus healed the demoniac there. Now Um-keis.
Concise Bible Dictionary:
The capital of the Roman province of Peraea. It is referred to in the Gospels as in “the country of the Gadarenes.” It has been identified with the ruins at Umm Keis, 32° 40' N, 35° 40' E, that is S. E. of the Sea of Galilee, but the town is too far from the sea to have been the scene of the miracle; besides which there is a deep ravine between the ruins of the town and the sea. There are many large tombs in the district, in which some of the rude inhabitants still take up their abode, as the demoniac had done (Mark 5:1-3). See GADARENES.
