Psalms 144:9

Fresh favours call for fresh returns of thanks; we must praise God for the mercies we hope for by his promise, as well as those we have received by his providence. To be saved from the hurtful sword, or from wasting sickness, without deliverance from the dominion of sin and the wrath to come, is but a small advantage. The public prosperity David desired for his people, is stated. It adds much to the comfort and happiness of parents in this world, to see their children likely to do well. To see them as plants, not as weeds, not as thorns; to see them as plants growing, not withered and blasted; to see them likely to bring forth fruit unto God in their day; to see them in their youth growing strong in the Spirit. Plenty is to be desired, that we may be thankful to God, generous to our friends, and charitable to the poor; otherwise, what profit is it to have our garners full? Also, uninterrupted peace. War brings abundance of mischiefs, whether it be to attack others or to defend ourselves. And in proportion as we do not adhere to the worship and service of God, we cease to be a happy people. The subjects of the Saviour, the Son of David, share the blessings of his authority and victories, and are happy because they have the Lord for their God.

I will sing a new song unto thee, O God. Weary of the false, I will adore the true. Fired with fresh enthusiasm, my gratitude shall make a new channel for itself. I will sing as others have done; but it shall be a new song, such as no others have sung. That song shall be all and altogether for my God: I will extol none but the Lord, from whom my deliverance has come. Upon a psaltery and an instrument of ten strings will I sing praises unto thee. His hand should aid his tongue, not as in the case of the wicked, cooperating in deceit; but his hand should unite with his mouth in truthful praise. David intended to tune his best instruments as well as to use his best vocal music: the best is all too poor for so great a God, and therefore we must not fall short of our utmost. He meant to use many instruments of music, that by all means he might express his great joy in God. The Old Testament dispensation abounded in types, and figures, and outward ritual, and therefore music dropped naturally into its place in the "worldly sanctuary"; but, after all, it can do no more than represent praise, and assist our expression of it; the real praise is in the heart, the true music is that of the soul. When music drowns the voice, and artistic skill takes a higher place than hearty singing, it is time that instruments were banished from public worship; but when they are subordinate to the song, as here, it is not for us to prohibit them, or condemn those who use them, though we ourselves greatly prefer to do without them, since it seems to us that the utmost simplicity of praise is far more congruous with the spirit of the gospel than pomp of organs. The private worshipper, singing his solo unto the Lord, has often found it helpful to accompany himself on some familiar instrument, and of this David in the present psalm is an instance, for he says, "I will sing praise unto thee", —that is, not so much in the company of others as by himself alone. He saith not "we", but "I."
