Passage
The mouth of the righteous talketh of wisdom, And his tongue speaketh justice.
The mouth of the righteous talketh of wisdom, And his tongue speaketh justice.
Psalms 37:28 For Jehovah loveth justice, And forsaketh not his saints; They are preserved for ever: But the seed of the wicked shall be cut off.
Psalms 37:29 The righteous shall inherit the land, And dwell therein for ever.
Psalms 37:30 The mouth of the righteous talketh of wisdom, And his tongue speaketh justice.
Psalms 37:31 The law of his God is in his heart; None of his steps shall slide.
Psalms 37:32 The wicked watcheth the righteous, And seeketh to slay him.
The verse centers on "mouth", "righteous", "talketh", "wisdom", "tongue", "speaketh", and "justice". It is saying that the verse draws attention to "mouth" and "righteous", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 29's "The righteous shall inherit the land And..." into verse 31's "The law of his God is in...", so "mouth" and "righteous" 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 "mouth" and "righteous" with trust shaped by these words, not by a vague optimism outside the passage.
