5. “The pleasant psaltery, with the harp.” I remember that we once intimated to your charity the difference of psaltery and harp.…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.
