In this case evidently compassion was the secret force that produced all the subsequent beneficence: yet we must not too readily count that all is safe for practical efficiency, when in presence of a brother's suffering this tender emotion begins to flutter about the heart. As the heart itself is deceitful, so also in turn are each of its affections; even those that in name and nature are good may swerve aside after they have sprung, and degenerate into selfishness. Probably both the priest and the Levite experienced some compassion as they looked on the pale and bleeding victim of lawless violence; perhaps they went away pleased with themselves on account of their tenderness, and somewhat angry with the wounded man for being wounded, and so hurting their sensibilities. The best things corrupted become the worst; and sometimes the sight of distress among poorer neighbours stirs into fermentation some of the worst elements of character in the comfortable classes. A little water may spring in the bottom of the well; but if it do not increase so as to fill the cavity, and freely overflow, it will become fetid where it lies, and more noisome than utter dryness. It is quite possible, as to emotion, to be very languishing over the misfortunes of others, and yet do the unfortunate as little good as the misanthrope who laughs at human sorrows. But while the spurious compassion is thus vile and worthless, the true is beyond expression beautiful and good. It breaks forth in power, and sweeps down whatever obstacles may be thrown in its way. In this parable the Lord expressly points to the fountain of compassion opened before he invites us to follow the stream of beneficence in its course. The nationality of the compassionate traveller is an important feature of the parable; he was a Samaritan. The Jews and Samaritans were locally nearest neighbours, but morally most unneighbourly. An enmity of peculiar strength and persistency kept the communities asunder from age to age. The alienation, originating in a difference of race, was kept alive by rivalry in religion. The Samaritans endeavoured to cover the defects of their pedigree by a zealous profession of orthodox forms in divine worship. The temple which they presumed to erect on Gerizzim as a rival to that of Jerusalem was naturally more odious to the Jews than others that were more distant in space, and more widely diverse in profession. Distinct traces of the keen reciprocal enmity that raged between the Jews and the Samaritans crop out here and there incidentally in the evangelical history, as in chapter ix. 54.
