To work out evil devices is as laughter to the fool; so wisdom is to a man of understanding.
Foolish ones laugh at guilt offering, but favor is among the upright ones.
Foolishness is joy to him who lacks understanding, but a man of understanding directs his going.
The wise in heart shall be called understanding, and sweetness of lips increases learning.
rejoicing to do evil; they delight in the perversity of the evil one,
Rejoice, O young man, in your youth. And make your heart glad in the days of your youth, and walk in the ways of your heart, and in the sight of your eyes; but know that for all these things God will bring you into judgment.
