Mark 5:13

And forthwith Jesus gave them leave
For the reason of this (See Gill on Matthew 8:32).

and the unclean spirits went out;
of the man, in whom they had for some time dwelt:

and entered into the herd of swine;
according to the leave given them by Christ: this shows not only the existence of spirits, but their going from one to another shows that they are circumscribed by space; that they are here, and not there, or there, and not here: there is an "ubi", a somewhere, where they are; and whilst there, are not elsewhere:

and the herd ran violently down a steep place into the sea.
The Syriac and Arabic versions read, "the herd ran to the rock", or "promontory", and "fell into the sea". The Ethiopic, the "herd grew mad, and was carried headlong into the sea": the sense is, that the devils having entered into them, it had a like effect on them, as on the man possessed; they ran mad, and were hurried on by the devils, to the rocks on the sea shore; where, falling down the precipice, they were all lost; and a considerable loss it was to their owners; for

they were about two thousand;
a very large herd, but there were devils enought in that one man, to possess all these, and run them into the sea:

and were choked in the sea;
not suffocated by the devils, but drowned in the waters of the sea, or lake, as Luke calls it; the lake of Gennesareth, or sea of Tiberias and Galilee; which, as often observed, were the same. Though some think it was not this lake or sea, but some other place of water near Gadara. Strabo says ^F5, that in the country of Gadara, there was a very bad laky water, of which if cattle tasted, they cast their hair, hoofs, and horns; which perhaps may be the same with what the Talmudists call ^F6, (rdgd hewlb) , "the whirlpool of Gadara"; said to be from the time of the deluge, and so called from its swallowing up every thing that came into it; but the sea of Tiberias seems rather to be the place, where this herd perished. The Jew ^F7 objects to the destroying this herd of swine as an unjust action, being a great injury to the owners; and seeks to blacken the character of Christ, as being concerned in it: but, as Bishop Kidder ^F8 well observes, it does not appear that Jesus destroyed it; it was the devils that did it: he suffered them indeed to go into it, nor did he restrain the natural power which they had; nor did he think fit to do it, nor was he obliged to it: but had he destroyed it himself, since he is Lord of all, the proprietor of all creatures, who has all under him, and at his disposal, can give and take away as he pleases, no charge of evil and injustice can be brought against him: and this should be satisfactory to a Christian, who believes him to be God over all blessed for ever; though it will not be to a Jew: let it therefore be further observed, that the owners of these swine were either Jews or Gentiles; if they were Jews, and they brought up these swine in order to eat them themselves, to destroy them was a just punishment, for their violation of the law of God, ( Deuteronomy 14:8 ) . And if they brought them up to sell to others, this was contrary to their own canons; (See Gill on Matthew 8:30), to the rules and customs of their own country, which were made as a fence to keep off from breaking the above law; and such a practice could only proceed from an avaricious disposition, of which this was a proper rebuke: or if they were Gentiles that were the owners of them, these were idolatrous persons, worshippers of devils; and it was but a righteous thing, to suffer the devils, whom they worshipped, to do this mischief to their property, to whom they devoted themselves soul and body; and a Jew cannot well find fault with this, who believes that idolaters cannot be punished too severely: add to this, what the above learned prelate observes; this practice of the Gentiles in breeding hogs, was a temptation to the Jews to follow the same business, and even to taste of the forbidden flesh; so that to use his words, it was in truth an act of grace and favour to the Jews, to remove from them so dangerous a snare, and so bad an example: and it may be added, by suffering the devils to go into the swine, several valuable ends were answered, infinitely preferable to the herd of swine; such as evincing the truth of the dispossession; showing the greatness of the mercy to the dispossessed; the power of Christ over the devils; and making for the spread of the fame of this miracle the more; as well as giving further proof of the malignity and mischievous disposition and actions of these evil spirits; by which the inhabitants of the adjacent places might learn, how hurtful they were to them, and what a blessing it was to be rid of them: and therefore ought to have been thankful to Christ for this dispossession, notwithstanding the loss of their swine; but such an effect it had not upon them, but the reverse, as the words following show.
