My mouth shall speak the praise of the Lord - That is, I will utter his praise. In view of all these things, in view of his character and doings, I will praise him. I will be found among those who honor him; who acknowledge him as the true God; who render homage for what he is, and thanks for what he has done.

And let all flesh bless his holy name forever and ever - All people; all that dwell upon the earth. Let his praise be universal and eternal. This is the language of true piety; all in whose bosom there is any true religion will heartily say Amen. No desire of a pious heart is more constant and strong than that God should be praised, adored, honored by all intelligent creatures; that he should be known and acknowledged in all the earth as the true God; that his praise should ascend from all parts of the universe forever. See the notes at Psalm 100:1-5.

Let all flesh bless his holy name - He is good to all, wants to save all, actually feeds and preserves all. And as near as שמר shamar is to שמד shamad, so near is he a Savior to those who stand on the brink of destruction, if they will look to him.

For the application of all this Psalm to the Church of Christ, see the analysis.

My mouth shall speak the praise of the Lord,.... Always, at all times, as long as he lived; and particularly when all the Lord's people shall be brought safe to glory, and the wicked destroyed; when, as Kimchi observes, he should live again with the dead that shall be raised;

and let all flesh bless his holy name for ever and ever; not every animal, or irrational creature; not carnal men, but spiritual men; such as are praying ones, that come to a God hearing prayer: these should be praising ones; such who have hearts of flesh given them, and are sensible of divine favours, as well as of their sinfulness and unworthiness; Jews and Gentiles, all sorts of men called by grace, all flesh on whom the Spirit of God is poured; these are all excited to praise and bless the holy name of the Redeemer, with the words and by the example of the psalmist. And thus the psalm ends as it begun, with praise and blessing.

My mouth shall speak the praise of the LORD: and let all {n} flesh bless his holy name for ever and ever.

(n) That is, all men will be bound to praise him.

21. (Compare Ps 33:21).

all flesh-(Ps 65:2). The Psalm ends, as it began, with ascriptions of praise, in which the pious will ever delight to join.

145:10-21 All God's works show forth his praises. He satisfies the desire of every living thing, except the unreasonable children of men, who are satisfied with nothing. He does good to all the children of men; his own people in a special manner. Many children of God, who have been ready to fall into sin, to fall into despair, have tasted his goodness in preventing their falls, or recovering them speedily by his graces and comforts. And with respect to all that are heavy laden under the burden of sin, if they come to Christ by faith, he will ease them, he will raise them. He is very ready to hear and answer the prayers of his people. He is present every where; but in a special way he is nigh to them, as he is not to others. He is in their hearts, and dwells there by faith, and they dwell in him. He is nigh to those that call upon him, to help them in all times of need. He will be nigh to them, that they may have what they ask, and find what they seek, if they call upon him in truth and sincerity. And having taught men to love his name and holy ways, he will save them from the destruction of the wicked. May we then love his name, and walk in his ways, while we desire that all flesh should bless his holy name for ever and ever.
