Psalm of David. The Targum adds,"spoken in prophecy,''as doubtless it was, under the inspiration of the Holy Spirit. Some think it was written by David, after a fit of illness, and his recovery from it, since he speaks of his diseases being healed, and his youth renewed; for which reason the Syriac interpreter suggests it was written in his old age; for he makes the subject of the psalm to be,"concerning coldness which prevailed upon him in old age;''but rather he wrote it when his heart was warm with a sense of the love of God, and spiritual blessings of grace flowing from thence; and in it celebrates and sings the benefits of New Testament times; and it is a psalm suitable to be sung by every believer, under a quick sense of divine favours: wherefore the above interpreter better adds,"also an instruction and thanksgiving by men of God;''whom the psalmist may very well be thought to personate, even in Gospel times; and much rather than the Jews in captivity, as Kimchi thinks.
Ver. 1. 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.
