Verse 1. - Bless the Lord, O my soul. Repeated in ver. 2; also at the end of the psalm; and again in Psalm 104:1, 35. To "bless" is more than to praise; it is to praise with affection and gratitude. The psalmist calls upon his own soul, and so on each individual soul, to begin the song of praise, which is to terminate in a general chorus of blessing from all creation (vers. 20-22). And all that is within me. "All my whole nature - intellect, emotion, feeling, sentiment - brain, heart, lungs, tongue," etc. Bless his holy Name; i.e. his manifested Personality, which is almost the same thing as himself.

103:1-5 By the pardon of sin, that is taken away which kept good things from us, and we are restored to the favor of God, who bestows good things on us. Think of the provocation; it was sin, and yet pardoned: how many the provocations, yet all pardoned! God is still forgiving, as we are still sinning and repenting. The body finds the melancholy consequences of Adam's offence, it is subject to many infirmities, and the soul also. Christ alone forgives all our sins; it is he alone who heals all our infirmities. And the person who finds his sin cured, has a well-grounded assurance that it is forgiven. When God, by the graces and comforts of his Spirit, recovers his people from their decays, and fills them with new life and joy, which is to them an earnest of eternal life and joy, they may then be said to return to the days of their youth, Job 33:25.Bless the Lord, O my soul,.... His better part, his soul, which comes immediately from God, and returns to him, which is immaterial and immortal, and of more worth than the world: God is to be served with the best we have; as with the best of our substance, so with the best of our persons; and it is the heart, or soul, which he requires to be given him; and such service as is performed with the soul or spirit is most agreeable to him; he being a Spirit, and therefore must be worshipped in spirit and in truth: unless the spirit or soul of a man, is engaged in the service of God, it is of little avail; for bodily exercise profiteth not; preaching, hearing, praying, and praising, should be both with the spirit, and with the understanding: here the psalmist calls upon his soul to "bless" the Lord; not by invoking or conferring a blessing on him, which as it is impossible to be done, so he stands in no need of it, being God, all sufficient, and blessed for evermore; but by proclaiming and congratulating his blessedness, and by giving him thanks for all mercies, spiritual and temporal:

and all that is within me, bless his holy name; meaning not only all within his body, his heart, reins, lungs, &c. but all within his soul, all the powers and faculties of it; his understanding, will, affections, and judgment; and all the grace that was wrought in him, faith, hope, love, joy, and the like; these he would have all concerned and employed in praising the name of the Lord; which is exalted above all blessing and praise; is great and glorious in all the earth, by reason of his works wrought, and blessings of goodness bestowed; and which appears to be holy in them all, as it does in the works of creation, providence, and redemption; at the remembrance of which holiness thanks should be given; for he that is glorious in holiness is fearful in praises, Psalm 97:12.
