Although serpents generally love music, yet here, as in most other cases, there are exceptions to the general rule; for I am told there is one species, which, instead of being allured by the charms of music, testifies a very remarkable aversion to it; and we need not wonder at this peculiarity, for we know that, generally speaking, all the human species, whether civilized or savage, are fond of music: but we know also that there are many individuals to whom it is rather an annoyance than a pleasure. The serpent I have alluded to is probably the species which the Psalmist had in his eye, when he compared wicked men to it, in respect of their dislike and antipathy to divine truth. It has been said, indeed, that there is a serpent, or adder, to which the Psalmist's comparison literally applies; that it actually covers one ear with its tail, and applies the other close upon the ground, to prevent itself being overcome with the charms of music, so as to run the hazard of being taken and killed. We know certainly, both from Scripture and observation, that the serpent is subtile above all beasts of the field, but this surely is a piece of cunning which is beyond its nature. It is surely much more rational to think that the Psalmist refers entirely to the utter dislike of the charmer and his music, which this serpent is characterized by; and, moreover, we have the words "stoppeth his ears," in Isaiah xxxiii. 15, employed to express the utmost disregard and abhorrence.
