Charles H. Spurgeon on Psalms 92:3

Upon an instrument of ten strings. Eusebius, in his comment on this psalm, says: "The psaltery of ten strings is the worship of the Holy Spirit performed by means of the five senses of the body, and by the five powers of the soul." And to confirm this interpretation, he quotes the apostle, 1Co 14:15: "I will pray with the spirit, and with the understanding also; I will sing with the spirit, and with the understanding also." "As the mind has its influence by which it moves the body, so the spirit has its own influence by which it moves the soul." Whatever may be thought of this gloss, one thing is pretty evident from it, that instrumental music was not in use in the church of Christ in the time of Eusebius, which was near the middle of the fourth century. Had any such thing then existed in the Christian Church, he would have doubtless alluded to or spiritualized it; or, as he quoted the words of the apostle above, would have shown that carnal usages were substituted for spiritual exercises. —Adam Clarke.
