14Knowledge is stored up by the wise, but the mouth of the foolish man is a destruction which is near.
15The property of the man of wealth is his strong town: the poor man's need is his destruction.
16The work of the upright gives life: the increase of the evil-doer is a cause of sin.
17He who takes note of teaching is a way of life, but he who gives up training is a cause of error.
18Hate is covered up by the lips of the upright man, but he who lets out evil about another is foolish.
