Now a great herd of pigs was feeding there on the hillside,
We have here an instance of Christ's dispossessing the strong man armed, and disposing of him as he pleased, to make it appear that he was stronger than he. This he did when he was come to the other side, whither he went through a storm; his business there was to rescue this poor creature out of the hands of Satan, and when he had done that, he returned.
Commenting on Mark 5:1-20
Now there was there, nigh unto the mountains,.... Where this man often was, Mar 5:5 according to Beza, the mountains of Galaad, which ran through that country, or the mountains that surrounded Tiberias. Some copies, as the Alexandrian copy and others, read "at", or "about the mountain", in the singular number. The Vulgate Latin and Arabic versions read, "about the mountain".
Now there was there nigh unto the mountains a great herd of swine feeding. (e) This whole country is for the most part very hilly, for the mountains of Galeed run through it.
