EXPOSITION
A PSALM of joy and thanksgiving for God's manifold mercies, especially for his loving kindness in forgiving sin and transgression (Psalms 103:3, Psalms 103:8-12, Psalms 103:17) passing into adoration of him upon his heavenly throne (Psalms 103:19), and a call on all creation to praise him (Psalms 103:20-22). The "title" assigns the psalm to David, and this view of its authorship is taken by Hengstenberg and Professor Alexander. But other critics see in "certain Aramaic terminations" indications of a later date. Whoever the author, we must regard the composition as less "the outbreathing of gratitude from one individual spirit" than "intended to be used as a national thanksgiving" (Kay).
The psalm divides itself into four portions:
the first (Psalms 103:1-5) an outburst of praise for blessings granted by God to each man severally;
the second (Psalms 103:6-14) an enumeration of his loving kindnesses towards his Church as a whole;
the third (Psalms 103:15-18) a representation of man's weakness and dependence on God; and
the fourth (Psalms 103:19-22) a glance at God's unchanging glory, and a call upon all his creation to bless and worship him.
