Concise Bible Dictionary:
These are also called GERGESENES and GERASENES in the different Greek MSS. As the Sea of Galilee had various names, so had the inhabitants according as they were associated with different districts in the vicinity. The Gadarenes abode on the east of the Sea of Galilee, where the Lord cured the two demoniacs, though Mark and Luke mention but one. One of them said his name was Legion. The demons obtained permission to go into a herd of swine, which, being possessed, rushed down into the water and were drowned. Travelers have found a place in the locality which has a steep decline into the sea and which exactly answers to the details of the gospel narrative (Matt. 8:28-34; Mark 5:1-20; Luke 8:26-39).
