11 The mouth of the upright man is a fountain of life, but the mouth of the evil-doer is a bitter cup.
12 Hate is a cause of violent acts, but all errors are covered up by love.
13 In the lips of him who has knowledge wisdom is seen; but a rod is ready for the back of him who is without sense.
14 Knowledge is stored up by the wise, but the mouth of the foolish man is a destruction which is near.
15 The property of the man of wealth is his strong town: the poor man's need is his destruction.
16 The work of the upright gives life: the increase of the evil-doer is a cause of sin.
17 He who takes note of teaching is a way of life, but he who gives up training is a cause of error.
