However it may be with the "time when and the manner" in which this idea of the Psalms has hit upon by the inspired David, he at least seems to have been the first, and indeed the only one, concerned in it, and that, too, at the earliest period, when he taught his fingers to tune the psaltery. For if any other before him showed the use of the psaltery and lute, it was at any rate in a very different way that such an one did it, only putting together some rude and clumsy contrivance, or simply employing the instrument, without singing either to melody or to words, but only amusing himself with a rude sort of pleasure. But after such he was the first to reduce the affair to rhythm, and order, and art, and also to wed the singing of the song with the melody. And, what is of greater importance, this most inspired of men sang to God, or of God, beginning in this wise even at the period when he was among the shepherds and youths in a simpler and humbler style, and afterwards when he became a man and a king, attempting something loftier and of more public interest. And he is said to have made this advance, especially after he had brought back the ark into the city. At that time he often danced before the ark, and often sang songs of thanksgiving and songs to celebrate its recovery. And then by and by, allocating the whole tribe of the Levites to the duty, he appointed four leaders of the choirs, viz., Asaph, Aman (Heman), Ethan, and Idithum (Jeduthun), inasmuch as there are also in all things visible four primal principles. And he then formed choirs of men, selected from the rest. And he fixed their number at seventy-two, having respect, I think, to the number of the tongues that were confused, or rather divided, at the time of the building of the tower. And what was typified by this, but that hereafter all tongues shall again unite in one common confession, when the Word takes possession of the whole world?
