"Have mercy upon me, O God, according to Thy lovingkindness: according to the multitude of Thy tender mercies blot out my transgressions!" Could we be permitted to possess any visible relic of King David, and to choose what that relic might be, it would not be the crown of Rabbah, that was set on his head, the weight of which was a talent of gold; it would not be even the sword of Goliath, though with David we might say of that weapon, "there is none like that;" no, surely it would be the harp of the sweet singer of Israel that we would choose as the most precious relic of him whom God's Holy Spirit inspired. But were that harp visibly before us, would it not appear almost sacrilege to lay a hand on its strings; would the mightiest or most gifted of mortals presume to waken its chords? Far, far better for us to have its divine music preserved for us in the Scriptures, where the little child can make it sound, and yet be not guilty of presumption; where it is accessible to all—to the dying pauper on her sick-bed, as well as to the crowned queen or mitred archbishop. The ragged child's Psalter is truly more precious than the identical harp of King David would be. And we have a key to the divine harmonies of the psalms which those who first stood listening around David did not possess. The blessed name of Jesus sounds to us thrilling through all the deepest chords of his music. If the Psalmist's strain be mournful, a Saviour's sufferings are its theme. "My God, my God, why hast Thou forsaken Me? . . . The assembly of the wicked have inclosed Me: they pierced My hands and My feet." If it burst into a loud song of triumph, its keynote is still the name of our Lord. "Thy throne, O God, is for ever and ever: the sceptre of Thy kingdom is a right sceptre. Thou hast loved righteousness, and hated iniquity: wherefore God, Thy God, hath anointed Thee with the oil of gladness above Thy fellows." It would be deeply interesting could we know how far King David himself understood the meaning of his own songs when, guided by the inspiring Spirit, he uttered dark sayings to the sound of his harp. Let us not quit this subject without alluding to the fact that the harp is the only instrument which is mentioned in Revelation as adding to the music of Heaven. * The elders beheld by St. John around the throne of the Lamb had "every one of them harps," when "they sung a new song, saying, Thou art worthy to take the book, and to open the seals thereof: for Thou wast slain, and hast redeemed us to God by Thy blood out of every kindred, and tongue, and people, and nation; and hast made us unto our God kings and priests: and we shall reign on the earth." * The trump of God, which shall awaken the dead, cannot be spoken of under such a term.
