Awake, psaltery and harp: I myself will awake early.

Matthew Henry's Concise Commentary

108:1-13 We may usefully select passages from different psalms, as here, Ps 57; 60, to help our devotions, and enliven our gratitude. When the heart is firm in faith and love, the tongue, being employed in grateful praises, is our glory. Every gift of the Lord honours and profits the possessor, as it is employed in God's service and to his glory. Believers may pray with assured faith and hope, for all the blessings of salvation; which are secured to them by the faithful promise and covenant of God. Then let them expect from him help in every trouble, and victory in every conflict. Whatever we do, whatever we gain, God must have all the glory. Lord, visit all our souls with this salvation, with this favour which thou bearest to thy chosen people.

Matthew Henry's Whole Bible Commentary

PSALM 108

This psalm begins with praise and concludes with prayer, and faith is at work in both. I. David here gives thanks to God for mercies to himself (v. 1-5). II. He prays to God for mercies for the land, pleading the promises of God and putting them in suit (v. 6-13). The former part it taken out of Ps. 57:7, etc., the latter out of Ps. 60:5, etc., and both with very little variation, to teach us that we may in prayer use the same words that we have formerly used, provided it be with new affections. It intimates likewise that it is not only allowable, but sometimes convenient, to gather some verses out of one psalm and some out of another, and to put them together, to be sung to the glory of God. In singing this psalm we must give glory to God and take comfort to ourselves.

Verses 1-5

We may here learn how to praise God from the example of one who was master of the art. 1. We must praise God with fixedness of heart. Our heart must be employed in the duty (else we make nothing of it) and engaged to the duty (v. 1): O God! my heart is fixed, and then I will sing and give praise. Wandering straggling thoughts must be gathered in, and kept close to the business; for they must be told that here is work enough for them all. 2. We must praise God with freeness of expression: I will praise him with my glory, that is, with my tongue. Our tongue is our glory, and never more so than when it is employed in praising God. When the heart is inditing this good matter our tongue must be as the pen of a ready writer, Ps. 45:1. David's skill in music was his glory, it made him famous, and this should be consecrated to the praise of God; and therefore it follows, Awake my psaltery and harp. Whatever gift we excel in we must praise God with. 3. We must praise God with fervency of affection, and must stir up ourselves to do it, that it may be done in a lively manner and not carelessly (v. 2): Awake, psaltery and harp; let it not be done with a dull and sleepy tune, but let the airs be all lively. I myself will awake early to do it, with all that is within me, and all little enough. Warm devotions honour God. 4. We must praise God publicly, as those that are not ashamed to own our obligations to him and our thankful sense of his favours, but desire that others also may be in like manner affected with the divine goodness (v. 3): I will praise thee among the people of the Jews; nay, I will sing to thee among the nations of the earth. Whatever company we are in we must take all occasions to speak well of God; and we must not be shy of singing psalms, though our neighbours hear us, for it looks like being ashamed of our Master. 5. We must, in our praises, magnify the mercy and truth of God in a special manner (v. 4), mercy in promising, truth in performing. The heavens are vast, but the mercy of God is more capacious; the skies are high and bright, but the truth of God is more eminent, more illustrious. We cannot see further than the heavens and clouds; whatever we see of God's mercy and truth there is still more to be seen, more reserved to be seen, in the other world. 6. Since we find ourselves so, defective in glorifying God, we must beg of him to glorify himself, to do all, to dispose all, to his own glory, to get himself honour and make himself a name (v. 5): Be thou exalted, O God! above the heavens, higher than the angels themselves can exalt thee with their praises, and let thy glory be spread over all the earth. Father, glorify thy own name. Thou hast glorified it; glorify it again. It is to be our first petition, Hallowed be thy name.
