Passage
Day to day uttereth speech, And night to night sheweth knowledge.
Day to day uttereth speech, And night to night sheweth knowledge.
Psalms 19:1 To the Overseer. --A Psalm of David. The heavens <FI>are<Fi> recounting the honour of God, And the work of His hands The expanse <FI>is<Fi> declaring.
Psalms 19:2 Day to day uttereth speech, And night to night sheweth knowledge.
Psalms 19:3 There is no speech, and there are no words. Their voice hath not been heard.
Psalms 19:4 Into all the earth hath their line gone forth, And to the end of the world their sayings, For the sun He placed a tent in them,
The verse centers on "uttereth", "speech", "night", "sheweth", and "knowledge". It is saying that the verse draws attention to "uttereth" and "speech", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 1's "To the Overseer A Psalm of David..." into verse 3's "There is no speech and there are...", so "uttereth" and "speech" belong inside that flow. 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 "uttereth" and "speech" with trust shaped by these words, not by a vague optimism outside the passage.
