14 But I will go on ever hoping, and increasing in all your praise. 15 My mouth will make clear your righteousness and your salvation all the day; for they are more than may be measured. 16 I will give news of the great acts of the Lord God; my words will be of your righteousness, and of yours only. 17 O God, you have been my teacher from the time when I was young; and I have been talking of your works of wonder even till now. 18 Now when I am old and grey-headed, O God, give me not up; till I have made clear your strength to this generation, and your power to all those to come. 19 Your righteousness, O God, is very high; you have done great things; O God, who is like you? 20 You, who have sent great and bitter troubles on me, will give me life again, lifting me up from the deep waters of the underworld. 21 You will make me greater than before, and give me comfort on every side. 22 I will give praise to you with instruments of music, O my God, for you are true; I will make songs to you with music, O Holy One of Israel. 23 Joy will be on my lips when I make melody to you; and in my soul, to which you have given salvation. 24 My tongue will be talking of your righteousness all the day; for those whose purpose is to do me evil have been crushed and put to shame.

Matthew Henry's Commentary on Psalm 71:14-24

Commentary on Psalm 71:14-24

(Read Psalm 71:14-24)

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.
