(9) See Psalm 33:2-3.

O God.--The only instance of Elohim in the last two books of the psalter with the exception of Psalms 108, which is a compilation from two older songs.

Verse 9. - I will sing a new song unto thee, O God. Another change of strain. The psalmist returns to his original theme of the praise of God (see vers. 1, 2), and promises a "new song," as in Psalm 40:3. Upon a psaltery and an instrument of ten strings will I sing praises unto thee; rather, upon a psaltery of ten strings (see the Revised Version, and comp. Psalm 33:2). Assyrian harps had commonly, in the earlier ages, either eight, nine, or ten strings ('Ancient Monarchies,' vol. 1. p. 530, 2nd edit.).

144:9-15 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,.... The author of his being, the Father of mercies, temporal and spiritual, and therefore to him praise is always due; a new song of praise is to be sung for new mercies; and as these are new every morning, and are renewed day by day, new songs should be sung continually: or this is a song suited to New Testament times, in which all things are become new; there is a new covenant of grace; and a new and living way to the throne of grace; a newly slain sacrifice; redemption newly wrought out, and therefore the new song of redeeming grace must be sung. Arama suggests that this refers to the days of the Messiah;

upon a psaltery, and an instrument of ten strings, will I sing praises unto thee; such instruments of music were used in the Old Testament dispensation, and were typical of the hearts of God's people; which are the harps they now strike upon, and where they make melody to the Lord; see Psalm 33:2.
