"The pleasant psaltery, 1 with the harp." I remember that we once intimated to your charity the difference of psaltery and harp. 2 ...For heavenly is the preaching of the word of God. But if we wait for heavenly things, let us not be sluggish in working at earthly things; because, "the psaltery is pleasant," but, "with the harp." The same is expressed in another way as above, "Take the Psalm, and give the tabret:" here for "Psalm," is put "psaltery," for "tabret," "harp." Of this, however, we are admonished, that to the preaching of God's word we make answer by bodily works.
