Passage
Be not afraid of sudden fear, nor of the power of the wicked falling upon thee.
Be not afraid of sudden fear, nor of the power of the wicked falling upon thee.
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.
Proverbs 3:25 Be not afraid of sudden fear, nor of the power of the wicked falling upon thee.
Proverbs 3:26 For the Lord will be at thy side, and will keep thy foot that thou be not taken.
Proverbs 3:27 Do not withhold him from doing good, who is able: if thou art able, do good thyself also.
The verse centers on "afraid", "sudden", "fear", "power", "wicked", "falling", "upon", and "thee". It is saying that the verse draws attention to "afraid" and "sudden", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 24's "If thou sleep thou shalt not fear..." into verse 26's "For the Lord will be at thy...", so "afraid" and "sudden" 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 "afraid" and "sudden" with trust shaped by these words, not by a vague optimism outside the passage.
