David
Psalm 103:1BSB·traditional attribution

Of David. Bless the LORD, O my soul; all that is within me, bless His holy name.

John Calvin Reformed @genevareformer

PSALM 103 By this psalm every godly man is taught to give thanks to God for the mercies bestowed upon himself in particular, and then for the grace which God has vouchsafed to all his chosen ones in common, by making a covenant of salvation with them in his law, that he might make them partakers of his adoption.

C.H. Spurgeon Reformed Baptist @princeofpreachers

Bless the Lord O my soul. Soul music is the very soul of music. The Psalmist strikes the best keymote when he begins with stirring up his inmost self to magnify the Lord. He soliloquizes, holds self-communion and exhorts himself, as though he felt that dulness would all too soon steal over his faculties, as, indeed, it will over us all, unless we are diligently on the watch.

Matthew Henry Presbyterian @wholebiblehenry

David is here communing with his own heart, and he is no fool that thus talks to himself and excites his own soul to that which is good. Observe, I. How he stirs up himself to the duty of praise, Psa 103:1, Psa 103:2. 1.
