Passage
Bless Jehovah, O my soul; And all that is within me, [bless] his holy name.
Bless Jehovah, O my soul; And all that is within me, [bless] his holy name.
Psalms 103:1 Bless Jehovah, O my soul; And all that is within me, [bless] his holy name.
Psalms 103:2 Bless Jehovah, O my soul, And forget not all his benefits:
Psalms 103:3 Who forgiveth all thine iniquities; Who healeth all thy diseases;
The verse centers on "bless", "jehovah", "soul", "within", "holy", and "name". It is saying that the verse draws attention to "bless" and "jehovah", so its meaning should be read from those terms before moving to application.
The next verse adds "Bless Jehovah O my soul And forget...", so "bless" and "jehovah" should be read forward into that movement. In Psalms context, the local focus is worship, trust, the LORD's kingship, and covenant mercy.
A plain takeaway is to answer the verse's own emphasis on "bless" and "jehovah" with trust shaped by these words, not by a vague optimism outside the passage.
