Psalms 150:5

"Praise Him on the well-sounding cymbals, praise Him on cymbals of jubilation" [Psalm 150:5]. Cymbals touch one another in order to sound, and therefore are by some compared to our lips. But I think it better to understand that God is in a manner praised on the cymbal, when each is honoured by his neighbour, not by himself, and then honouring one another, they give praise to God. But lest any should understand such cymbals as sound without life, therefore I think he added, "on cymbals of jubilation." For "jubilation" that is, unspeakable praise, proceeds not, save from life. Nor do I think that I should pass over what musicians say, that there are three kinds of sounds, by voice, by breath, by striking: by voice, uttered by throat and windpipe, when man sings without any instrument; by breath, as by pipe, or anything of that sort: by striking, as by harp, or anything of that kind. None then of these kinds is omitted here: for there is voice in the choir, breath in the trumpet, striking in the harp, representing mind, spirit, body, but by similitudes, not in the proper sense of the words. When then he proposed, "Praise God in His saints," to whom said he this, save to themselves? And in whom are they to praise God, save in themselves? For you, says he, are "His saints;" you are "His strength," but that which He wrought in you; you are "His mighty works, and the multitude of His greatness," which He has wrought and set forth in you. You are "trumpet, psaltery, harp, timbrel, choir, strings, and organ, cymbals of jubilation sounding well," because sounding in harmony. All these are you: let nought that is vile, nought that is transitory, nought that is ludicrous, be here thought of.
