7.

As there are "psalms," and "songs," and "psalms of song," and "songs of psalmody," ¹ it remains that we discuss the difference between these. We think, then, that the "psalms" are those which are simply played to an instrument, without the accompaniment of the voice, and (which are composed) for the musical melody of the instrument; and that those are called "songs" which are rendered by the voice in concert with the music; and that they are called "psalms of song" when the voice takes the lead, while the appropriate sound is also made to accompany it, rendered harmoniously by the instruments; and "songs of psalmody," when the instrument takes the lead, while the voice has the second place, and accompanies the music of the strings. And thus much as to the letter of what is signified by these terms. But as to the mystical interpretation, it would be a "psalm" when, by smiting the instrument, viz., the body, with good deeds we succeed in good action though not wholly proficient in speculation; and a "song," when, by revolving the mysteries of the truth, apart from the practical, and assenting fully to them, we have the noblest thoughts of God and His oracles, while knowledge enlightens us, and wisdom shines brightly in our souls; and a "song of psalmody," when, while good action takes the lead, according to the word, "If thou desire wisdom, keep the commandments, and the Lord shall give her unto thee," ² we understand wisdom at the same time, and are deemed worthy by God to know the truth of things, till now kept hid from us; and a "psalm of song," when, by revolving with the light of wisdom some of the more abstruse questions pertaining to morals, we first become prudent in action, and then also able to tell what, and when, and how action is to be taken. And perhaps this is the reason why the first inscriptions nowhere contain the word "songs," but only "psalm" or "psalms;" for the saint does not begin with speculation; but when he has become in a simple way a believer, according to orthodoxy, he devotes himself to the actions that are to be done. For this reason, also, are there many "songs" at the end; and wherever there is the word "degrees," there we do not find the word "psalm," whether by itself alone or with any addition, but only "songs." For in the "degrees" (or "ascents"), the saints will be engaged in nothing but in speculation alone. And let the account which we have offered, following the indications given in the interpretation of the Seventy, suffice for this subject in general.
