He said unto them, Go. — Men have asked sometimes, in scorn, why the word was spoken; why permission was given for a destructive work which seemed alike needless and fruitless. The so-called rationalistic explanation, that the demoniacs drove the swine down the cliff in a last paroxysm of frenzy, is no solution of the difficulty, for, even if that hypothesis were on other grounds tenable, it is clear that our Lord’s words sanctioned what they did. We are at least on the right track in suggesting that only in some such way could the man be delivered from the inextricable confusion between himself and the unclean spirits in which he had been involved. Not till he saw the demoniac forces that had oppressed him transferred to the bodies of other creatures, and working on them the effects which they had wrought on him, could he believe in his own deliverance. Those who measure rightly the worth of a human spirit thus restored to itself, to its fellow-men, and to God, will not think that the destruction of brute life was too dear a price to pay for its restoration. Other subordinate ends — such, e.g., as that it was a penalty on those who kept the unclean beasts for their violation of the Law, or that it taught men that it was through their indulgence of the swinish nature in themselves that they became subject to the darker and more demoniac passions — have been suggested with more or less plausibility.
Down a steep place. — Literally, down the cliff.
