Passage
The righteous shall possess the land, and dwell therein for ever.
The righteous shall possess the land, and dwell therein for ever.
Psalms 37:27 Depart from evil, and do good, and dwell for evermore;
Psalms 37:28 for Jehovah loveth judgment, and will not forsake his saints: They are preserved for ever; but the seed of the wicked shall be cut off.
Psalms 37:29 The righteous shall possess the land, and dwell therein for ever.
Psalms 37:30 The mouth of the righteous proffereth wisdom, and his tongue speaketh judgment;
Psalms 37:31 the law of his God is in his heart; his goings shall not slide.
The verse centers on "righteous", "shall", "possess", "land", "dwell", "therein", and "ever". It is saying that the verse draws attention to "righteous" and "shall", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 28's "for Jehovah loveth judgment and will not..." into verse 30's "The mouth of the righteous proffereth wisdom...", so "righteous" and "shall" 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 "righteous" and "shall" with trust shaped by these words, not by a vague optimism outside the passage.
