Psalms 103:1

Bless the Lord, O my soul -The word “bless,” as applied to God, means to praise, implying always a strong affection for him as well as a sense of gratitude. As used with reference to people, the word implies a “wish” that they may be blessed or happy, accompanied often with a prayer that they may be so. Such is the purport of the “blessing” addressed to a congregation of worshippers. CompareNumbers 6:23-27. The word “soul” here is equivalent to mind or heart: my mental and moral powers, as capable of understanding and appreciating his favors. The soul of man was “made” to praise and bless God; to enjoy his friendship; to delight in his favor; to contemplate his perfections.
