Theophylact of Ohrid — as excerpted in the Catena Aurea on Mark 5:1-20

“But amazed at the miracle, which they had heard, they were afraid, and for this reason they beseech him to depart out of their borders; which is expressed in what follows: And they began to pray him to depart out of their coasts; for they feared lest some time or other they should suffer a like thing: for, saddened at the loss of their swine, they reject the presence of the Saviour.”
