Passage
Thou hast put gladness in my heart, more than in the time that their corn and their wine increased.
Thou hast put gladness in my heart, more than in the time that their corn and their wine increased.
Psalms 4:5 Offer the sacrifices of righteousness, and put your trust in the LORD.
Psalms 4:6 There be many that say, Who will shew us any good? LORD, lift thou up the light of thy countenance upon us.
Psalms 4:7 Thou hast put gladness in my heart, more than in the time that their corn and their wine increased.
Psalms 4:8 I will both lay me down in peace, and sleep: for thou, LORD, only makest me dwell in safety.
The verse centers on "thou", "hast", "gladness", "heart", "than", "time", "corn", and "wine". 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 "There be many that say Who will..." into verse 8's "I will both lay me down in...", 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.
