15. Good understanding giveth grace, And the way of the treacherous [is] hard.
16. Every prudent one dealeth with knowledge, And a fool spreadeth out folly.
17. A wicked messenger falleth into evil, And a faithful ambassador is healing.
18. Whoso is refusing instruction--poverty and shame, And whoso is observing reproof is honoured.
19. A desire accomplished is sweet to the soul, And an abomination to fools [is]: Turn from evil.
20. Whoso is walking with wise men is wise, And a companion of fools suffereth evil.
