But I will hope continually. David again, as having obtained the victory, prepares himself for thanksgiving. There is, however, no doubt, that during the time when the wicked derided his simplicity, he struggled manfully amidst his distresses, as may be gathered from the word hope. Although, to outward appearance, there was no prospect of deliverance from his troubles, and although the wicked ceased not proudly to pour contempt upon his trust in God, he nevertheless determined to persevere in the exercise of hope; even as it is a genuine proof of faith, to look exclusively to the Divine promise, in order to be guided by its light alone amidst the thickest darkness of afflictions. The strength, then, of the hope of which David speaks, is to be estimated by the conflicts which he at that time sustained. In saying, I will add to all thy praises, he shows the confidence with which he anticipated a desirable escape from his troubles. It is as if he had said -- Lord, I have been long accustomed to receive benefits from thee, and this fresh accession to them, I doubt not, will furnish me with new matter for celebrating thy grace.

But I will hope continually - I will always cherish hope; I will not give up to despair. I will trust in God whatever may be the number, the power, and the confidence of my enemies. None of these things shall make me despair, for as long as I have a God, I have every ground for hope. No man should despair who has God for his Friend. Compare Psalm 42:5, Psalm 42:11; Psalm 43:5.
And will yet praise thee more and more - literally, "I will add upon all thy praise." That is, I will accumulate it; I will increase it. He saw abundant cause in the past for praising God; he had such confidence in him, and he felt such an assurance that he would interpose in his behalf, that he did not doubt that in the future dealings of God with him, he would have every reason to "add" to that praise.

I will hope continually - I shall expect deliverance after deliverance, and blessing after blessing; and, in consequence, I will praise thee more and more. As thy blessings abound, so shall my praises.

But I will hope continually,.... For deliverance and salvation from present outward troubles, for; more grace here and glory hereafter: it is the excellency of the grace of hope to be exercised in times of affliction and distress, and with Abraham to believe in hope against hope; and then it is that this grace is eminently and remarkably useful: it is an anchor to the soul when in distress, which keeps it firm and steadfast; and an helmet, which covers the head in the day of battle; in the exercise of which the believer glories in tribulation: it is an abiding grace, and should be continually exercised by those that have it, which is to abound in it; but this must be through the power of the Holy Ghost, Romans 15:13;
and will yet praise thee more and more; or "will add to all thy praise" (b); to former praises and thanksgivings, fresh ones, as his mercies were renewed to him, and he was daily loaded with benefits.
(b) "omnibus laudibus tuis adjiciam", Tigurine version.

The psalmist declares that the righteousness of Christ, and the great salvation obtained thereby, shall be the chosen subject of his discourse. Not on a sabbath only, but on every day of the week, of the year, of his life. Not merely at stated returns of solemn devotion, but on every occasion, all the day long. Why will he always dwell on this? Because he knew not the numbers thereof. It is impossible to measure the value or the fulness of these blessings. The righteousness is unspeakable, the salvation everlasting. God will not cast off his grey-headed servants when no longer capable of labouring as they have done. The Lord often strengthens his people in their souls, when nature is sinking into decay. And it is a debt which the old disciples of Christ owe to succeeding generations, to leave behind them a solemn testimony to the advantage of religion, and the truth of God's promises; and especially to the everlasting righteousness of the Redeemer. Assured of deliverance and victory, let us spend our days, while waiting the approach of death, in praising the Holy One of Israel with all our powers. And while speaking of his righteousness, and singing his praises, we shall rise above fears and infirmities, and have earnests of the joys of heaven. The work of redemption ought, above all God's works, to be spoken of by us in our praises. The Lamb that was slain, and has redeemed us to God, is worthy of all blessing and praise.

The ruin of his enemies, as illustrating God's faithfulness, is his deliverance, and a reason for future confidence.
