Adam Clarke's Bible Commentary Verse 1. The wicked flee ] Every wicked man, however bold he may appear, is full of dreary apprehensions relative to both worlds. But the righteous has true courage, being conscious of his own innocence, and the approbation of his God. "The unpitious fleeith". - Old MS. Bible. This word is often used for impious, wicked, ungodly; hence it appears that our word pity anciently meant piety or godliness.
Matthew Henry Commentary
Verses 1 - Sin makes men cowards. Whatever difficulties the righteous meet in the way of duty, they are not daunted.
