All thy works, etc. Though many would suppress God's praises, observing a wicked silence regarding them, David declares that they shine forth everywhere, appear of themselves, and are sounded, as it were, by the very dumb creatures. He then assigns the special work of declaring them to believers, who have eyes to perceive God's works, and know that they cannot be employed better than in celebrating his mercies. What is added -- they shall speak the glory of thy kingdom -- I consider to have reference only to believers. If any incline to think that these words rather apply to God's creatures universally, I would not object to that view. But the particular kind of speaking or teaching which David here refers to, applies only to saints. Accordingly I have retained the future tense of the verbs, rather than the optative mood, as others have done. In using the term kingdom, David intimates that this is the tendency of the manifestation of God's works, to reduce the whole world to a state of order, and subject it to his government. He insists upon the excellency of this kingdom, that men may know that things are to be considered as in disorder and confusion, unless God alone be acknowledged supreme. He denies it to be transitory, like all earthly kingdoms, asserting that it will stand fast for ever. And to call our attention more particularly to its everlasting nature, he breaks out into an admiring exclamation, and addresses his discourse to God.

All thy works shall praise thee - Or, do praise thee; that is, all thy works show what thou art, and combine in setting forth thy perfections. See the notes at Psalm 19:1.
And thy saints shall bless thee - Or, do bless thee. All those who are holy in heaven and on earth, the angels around thy throne, and thy people below, all combine to proclaim thy praise.

All thy works shall praise thee - The God who is good to all.
Thy saints - חסידיך chasideycha, thy compassionate ones; those who are partakers of thy great mercy, Psalm 145:8. These shall bless thee, because they know, they feel, that thou willest the salvation of all. The dark, the gloomy, the hard-hearted, the narrow-minded bigots, who never have had thy love shed abroad in their hearts, can unfeelingly deal in the damnation of their fellows.

All thy works shall praise thee, O Lord,.... Not all his works or creatures in general; though these do objectively praise him, or are the cause rather of others praising him on their account: but those who are in a special manner the works of his hands, of his powerful and efficacious grace; when he has formed for himself, that they may show forth his praise; such as are a chosen generation, a royal priesthood, an holy nation, a peculiar people: these in an eminent sense, in the best way and manner, praise their blessed Saviour and Redeemer; see Isaiah 43:21;
and thy saints shall bless thee: which are mentioned last, not as distinct from the former; but as explanative of them, as well as of their work: these are they that are set apart by the Lord, on whom his favours are bestowed; to whom Christ is made sanctification, and who are sanctified by his blood, and also by his Spirit; and, being sensible of the blessings of grace they receive from him, rise up and call him blessed, and ascribe blessing, honour, glory, and praise to him, for ever and ever.

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.

bless--as in Psalm 145:1, to praise with reverence, more than merely to praise.
