Passage
For the Lord knoweth the way of the righteous, and the way of the wicked shall perish.
For the Lord knoweth the way of the righteous, and the way of the wicked shall perish.
Psalms 1:4 The wicked are not so, but as the chaffe, which the winde driueth away.
Psalms 1:5 Therefore the wicked shall not stande in the iudgement, nor sinners in the assemblie of the righteous.
Psalms 1:6 For the Lord knoweth the way of the righteous, and the way of the wicked shall perish.
The verse centers on "lord", "knoweth", "righteous", "wicked", "shall", and "perish". It is saying that the verse draws attention to "lord" and "knoweth", so its meaning should be read from those terms before moving to application.
The prior verse says "Therefore the wicked shall not stande in...", giving immediate footing for "lord" and "knoweth". 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 "lord" and "knoweth" with trust shaped by these words, not by a vague optimism outside the passage.
