Charles H. Spurgeon on Psalms 33:2

(last clause). It is said that David praised God upon an instrument of ten strings; and he would never have told how many strings there were, but that without doubt he made use of them all. God hath given all of us bodies, as it were, instruments of many strings; and can we think it music good enough to strike but one string, to call upon him with our tongues only? No, no; when the still sound of the heart by holy thoughts, and the shrill sound of the tongue by holy words, and the loud sound of the hands by pious works, do all join together, that is God's concert, and the only music wherewith he is affected. Sir Richard Baker.
