Passage
And there shall be life to thy soul, and grace to thy mouth.
And there shall be life to thy soul, and grace to thy mouth.
Proverbs 3:20 By his wisdom the depths have broken out, and the clouds grow thick with dew.
Proverbs 3:21 My son, let not these things depart from thy eyes: keep the law and counsel:
Proverbs 3:22 And there shall be life to thy soul, and grace to thy mouth.
Proverbs 3:23 Then shalt thou walk confidently in thy way, and thy foot shall not stumble:
Proverbs 3:24 If thou sleep, thou shalt not fear: thou shalt rest, and thy sleep shall be sweet.
The verse centers on "grace", "shall", "life", "soul", and "mouth". It is saying that the verse draws attention to "grace" and "shall", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 21's "My son let not these things depart..." into verse 23's "Then shalt thou walk confidently in thy...", so "grace" and "shall" belong inside that flow. In Proverbs context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "grace" and "shall" with trust shaped by these words, not by a vague optimism outside the passage.
