Proverbs 4:16
For they sleep not, except they have done mischief; and their sleep is taken away, unless they cause some to fall.
Wicked friends will destroy you. If you want to grow in wisdom and godliness, you must avoid foolish companions. Paul wrote, evil communications corrupt good manners (I Cor 15:33). Solomon soberly warned his son to stay far away from evil men (Pr 4:14-15). Their hearts are controlled by sin and their thoughts dedicated to it (Pr 4:16-17).
Good and evil are opposites, and good men and evil men are also opposites. They are perpetual enemies (Pr 29:27). Wise and just men choose to live successful lives, and God blesses them with light (Pr 4:18). Foolish and wicked men live in darkness, stumbling through a dysfunctional life by the blindness of arrogant and ignorant hearts (Pr 4:19).
