Passage
Bless Jehovah, all his works, in all places of his dominion. Bless Jehovah, O my soul!
Bless Jehovah, all his works, in all places of his dominion. Bless Jehovah, O my soul!
Psalms 103:20 Bless Jehovah, ye his angels, mighty in strength, that execute his word, hearkening unto the voice of his word.
Psalms 103:21 Bless Jehovah, all ye his hosts; ye ministers of his that do his will.
Psalms 103:22 Bless Jehovah, all his works, in all places of his dominion. Bless Jehovah, O my soul!
The verse centers on "bless", "jehovah", "works", "places", "dominion", and "soul". 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 prior verse says "Bless Jehovah all ye his hosts ye...", giving immediate footing for "bless" and "jehovah". 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.
