Passage
Prayse the Lord, all ye his workes, in all places of his dominion: my soule, prayse thou the Lord.
Prayse the Lord, all ye his workes, in all places of his dominion: my soule, prayse thou the Lord.
Psalms 103:20 Prayse the Lord, ye his Angels, that excell in strength, that doe his commandement in obeying the voyce of his worde.
Psalms 103:21 Prayse the Lord, all ye his hostes, ye his seruants that doe his pleasure.
Psalms 103:22 Prayse the Lord, all ye his workes, in all places of his dominion: my soule, prayse thou the Lord.
The verse centers on "prayse", "lord", "workes", "places", "dominion", "soule", and "thou". It is saying that the verse draws attention to "prayse" and "lord", so its meaning should be read from those terms before moving to application.
The prior verse says "Prayse the Lord all ye his hostes...", giving immediate footing for "prayse" and "lord". 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 "prayse" and "lord" with trust shaped by these words, not by a vague optimism outside the passage.
