Albert Barnes Commentary Psalms 104:1

"Bless Jehovah, O my soul. O Jehovah my God, thou art very great; Thou art clothed with honor and majesty:" — Psalms 104:1 (ASV)

Bless the Lord, O my soul - See (Psalms 103:1).

O Lord my God, thou art very great - This is a reason why the psalmist calls on his soul to bless God; namely, for the fact that He is so exalted; so vast in His perfections; so powerful, so wise, so great.

Thou art clothed with honor and majesty - That is, with the emblems of honor and majesty, as a king is arrayed in royal robes. Creation is the garment with which God has invested Himself. Compare the notes at (Psalms 93:1).
