(31) The Lord shall rejoice.--The poet still follows Genesis in representing God as looking on His finished work with pleasure, but he says nothing of a sabbath. But it is possible that the thought of the sabbath hymns of praise led him to join man with the Divine Being in celebrating the glory and perfection of creation.

Verse 31. - The glory of the Lord shall endure forever; rather, let the glory of the Lord, etc. The psalmist prays that there may be no further interruption of the glorious course of nature besides the Deluge, which has come into his thoughts in connection with the destruction of animal life (ver. 29). Henceforward he trusts and prays that the Lord shall rejoice in his works, and not again repent him that he has made them (Genesis 6:7).

104:31-35 Man's glory is fading; God's glory is everlasting: creatures change, but with the Creator there is no variableness. And if mediation on the glories of creation be so sweet to the soul, what greater glory appears to the enlightened mind, when contemplating the great work of redemption! There alone can a sinner perceive ground of confidence and joy in God. While he with pleasure upholds all, governs all, and rejoices in all his works, let our souls, touched by his grace, meditate on and praise him.The glory of the Lord shall endure for ever,.... The glory which arises from the works of his hands, which is due unto him, and shall be given him; this is opposed to the perishing and fading glory of all created beings: and as Christ is the person spoken of throughout the whole psalm, this may be understood of his glory as the only begotten of the Father; and which is equal to his Father's glory, and is the same yesterday, today, and for ever; and of the glory of his office as Mediator: and of all his works of nature and grace, of creation and redemption: nor will there be creatures wanting, angels and men to glorify his name, to all eternity. The Targum, Septuagint, Vulgate Latin, and all the Oriental versions render it as a prayer, "let the glory of the Lord be for ever"; or, let him be for ever glorified, on account of the perfections of his nature, and the works of his hands; as he will and ought to be.

The Lord shall rejoice in his works; being well pleased with them, as he was with the works of creation; they appearing, on a survey of them, to be all very good, Genesis 1:31 so he rejoices in the sustaining and preservation of them; and the rather when he is glorified in them. And this should be a reason why glory should be given him, that he may rejoice in his works, and not be grieved, as he is sometimes said to be and to repent of his making them, Genesis 6:6. Christ rejoices in the work of redemption, which he undertook and performed with pleasure; he rejoiced at the finishing it, and he rejoices in the application of it to his people and will rejoice in their complete enjoyment of it; they being the objects of his love, in whom he has an interest; whom he engaged for, are the purchase of his blood, and for whom he prays and intercedes; he rejoices in them as the work of his hands now; in their persons, who are his "hephzibah", in whom he delights; "his beulah", to whom he is married: he rejoices in his own grace wrought in them, and in the exercise of it on him; he rejoices over them to do them good, and never ceases doing good to them and for them.
