Passage
When I called upon him, the God of my justice heard me: when I was in distress, thou hast enlarged me. Have mercy on me: and hear my prayer.
When I called upon him, the God of my justice heard me: when I was in distress, thou hast enlarged me. Have mercy on me: and hear my prayer.
Psalms 4:1 Unto the end, in verses. A psalm for David.
Psalms 4:2 When I called upon him, the God of my justice heard me: when I was in distress, thou hast enlarged me. Have mercy on me: and hear my prayer.
Psalms 4:3 O ye sons of men, how long will you be dull of heart? why do you love vanity, and seek after lying?
Psalms 4:4 Know ye also that the Lord hath made his holy one wonderful: the Lord will hear me when I shall cry unto him.
The verse centers on "called", "mercy", "upon", "justice", "heard", "distress", "thou", and "hast". It is saying that the verse draws attention to "called" and "mercy", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 1's "Unto the end in verses A psalm..." into verse 3's "O ye sons of men how long...", so "called" and "mercy" 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 "called" and "mercy" with trust shaped by these words, not by a vague optimism outside the passage.
