John Gill's Exposition of the Whole Bible
Psalms 103 - Introduction
INTRODUCTION TO PSALM 103
A 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.
