Passage
Thou hast put gladness in my heart, More than [they have] when their grain and their new wine are increased.
Thou hast put gladness in my heart, More than [they have] when their grain and their new wine are increased.
Psalms 4:5 Offer the sacrifices of righteousness, And put your trust in Jehovah.
Psalms 4:6 Many there are that say, Who will show us [any] good? Jehovah, lift thou up the light of thy countenance upon us.
Psalms 4:7 Thou hast put gladness in my heart, More than [they have] when their grain and their new wine are increased.
Psalms 4:8 In peace will I both lay me down and sleep; For thou, Jehovah, alone makest me dwell in safety. Psalm 5 For the Chief Musician; with the Nehiloth. A Psalm of David.
The verse centers on "thou", "hast", "gladness", "heart", "than", "grain", "wine", and "increased". It is saying that the verse draws attention to "thou" and "hast", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 6's "Many there are that say Who will..." into verse 8's "In peace will I both lay me...", so "thou" and "hast" 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 "thou" and "hast" with trust shaped by these words, not by a vague optimism outside the passage.
