Passage
For be ye sure that the Lord hath chosen to himselfe a godly man: the Lord will heare when I call vnto him.
For be ye sure that the Lord hath chosen to himselfe a godly man: the Lord will heare when I call vnto him.
Psalms 4:1 To him that excelleth on Neginoth. A Psalme of Dauid. Heare me when I call, O God of my righteousnes: thou hast set me at libertie, when I was in distresse: haue mercie vpon me and hearken vnto my prayer.
Psalms 4:2 O ye sonnes of men, howe long will yee turne my glory into shame, louing vanitie, and seeking lyes? Selah.
Psalms 4:3 For be ye sure that the Lord hath chosen to himselfe a godly man: the Lord will heare when I call vnto him.
Psalms 4:4 Tremble, and sinne not: examine your owne heart vpon your bed, and be still. Selah.
Psalms 4:5 Offer the sacrifices of righteousnes, and trust in the Lord.
The verse centers on "sure", "lord", "hath", "chosen", "himselfe", "godly", and "heare". It is saying that the verse draws attention to "sure" and "lord", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 2's "O ye sonnes of men howe long..." into verse 4's "Tremble and sinne not examine your owne...", so "sure" and "lord" 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 "sure" and "lord" with trust shaped by these words, not by a vague optimism outside the passage.
