14 But I will always hope,
and will add to all of your praise. 15 My mouth will tell about your righteousness,
and of your salvation all day,
though I don’t know its full measure. 16 I will come with the mighty acts of the Lord Yahweh.
I will make mention of your righteousness, even of yours alone. 17 God, you have taught me from my youth.
Until now, I have declared your wondrous works. 18 Yes, even when I am old and gray-haired, God, don’t forsake me,
until I have declared your strength to the next generation,
your might to everyone who is to come. 19 Your righteousness also, God, reaches to the heavens;
you have done great things.
God, who is like you? 20 You, who have shown us many and bitter troubles,
you will let me live.
You will bring us up again from the depths of the earth. 21 Increase my honor,
and comfort me again. 22 I will also praise you with the harp for your faithfulness, my God.
I sing praises to you with the lyre, Holy One of Israel. 23 My lips shall shout for joy!
My soul, which you have redeemed, sings praises to you! 24 My tongue will also talk about your righteousness all day long,
for they are disappointed, and they are confounded,
who want to harm me.

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.
