'Unwise' in the Bible

Do ye thus requite Jehovah, Foolish and unwise people? Is not he thy father that hath bought thee? Hath he not made thee and established thee?

See therefore how ye walk carefully, not as unwise but as wise,

But those who desire to be rich fall into temptation and a snare, and many unwise and hurtful lusts, which plunge men into destruction and ruin.
