Passage
The heavens declare the glory of God; and the firmament sheweth his handywork.
The heavens declare the glory of God; and the firmament sheweth his handywork.
Psalms 19:1 The heavens declare the glory of God; and the firmament sheweth his handywork.
Psalms 19:2 Day unto day uttereth speech, and night unto night sheweth knowledge.
Psalms 19:3 There is no speech nor language, where their voice is not heard.
The verse centers on "heavens", "declare", "glory", "firmament", "sheweth", and "handywork". It is saying that the verse draws attention to "heavens" and "declare", so its meaning should be read from those terms before moving to application.
The next verse adds "Day unto day uttereth speech and night...", so "heavens" and "declare" 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 "heavens" and "declare" with trust shaped by these words, not by a vague optimism outside the passage.
