The word פרט, pereth, means to divide; so some explain it, and derive it from the clusters which remain after the vintage, because there are not then thick grapes, but a cluster here and there, and a great distance between: hence they think that the participle הפורטים, epurethim, is to be taken here metaphorically as meaning to divide by marks, as music has its various notes; for except there be a distinct variety in singing, the sound would be confused, and would produce no pleasing effect. Who sing then with the harps and have invented for themselves, after the example of David, musical instruments.

The Prophet still continues his discourse, and shows that these men lived sumptuously; as though they did not belong to the common class, they delighted themselves, against God’s will, not only in the common mode of living, but even sought new pleasures, as if they were continually at marriage feasts, or celebrating birthdays. As then they had no season for mourning, they pursued their own indulgences; and this is what the Prophet now reprehends. If then any one thinks that music is in these words condemned, he is much deceived, as it appears from the context. Indeed, the Prophet never dealt so rigidly with that people, but he ever kept to this point — that they were extremely torpid, nay, destitute of common sense, who perceived not that God showed himself angry with them, in order that they might flee immediately to the standard of repentance and humbly deprecate, with mourning, the wrath of God, as they ought to have done. It was therefore meet ever to set before them Gods wrath, which ought to have humbled the Jews and the Israelites, inasmuch as they ever obstinately set up against God their own indifference.

In saying that after the example of David they invented for themselves musical instruments, he no doubt greatly aggravated their sin by this comparison: for it is not likely that they had abused this pretext, as hypocrites do, who are wont to boast of the examples of the saints, when they seek to disguise their own vices, — “What!” some will say, “Did not David use musical instruments?” Others will say, “Had not Solomon very splendid palaces?” And some will add, “Had not Abraham a company of servants in his house?” So every one lays hold on what may avail for an excuse: and thus the examples of the saints are absurdly referred to by many. But it seems not probable that this was done by those whom Amos now addresses: but, on the contrary, he appears sharply to reprove them for provoking God’s wrath by self indulgence, and for manifesting their perverseness, while David employed musical instruments in the exercises of religion, to raise up his mind to God. No doubt, David, when in a peaceful state, after having been delivered from all dangers, could also amuse himself: but he applied musical instruments to another purpose — to sound forth the praises of God in the temple, that thereby he and other godly persons might together elevate their thoughts to a religious devotion. While David then, even in a state of peace and prosperity, did not allow his mind to become sunk in vain self-indulgences, these men, when God appeared angry, when he spread terror by so many tokens of his vengeance, yet dared contumaciously to follow their own ways, so that they left off nothing of their usual pomp and of their accustomed pleasures.

We now see the design of the comparison which the Prophet makes: He aggravates, I have no doubt, their sin, because they regarded not the example of David, but transferred musical instruments to serve the purpose of gross and beastly indulgences, and thus they did when God was opposed to them, when he had begun to terrify them by his vengeance.
