Proverbs 14:7-9 Go from the presence of a foolish man, when thou perceives not in him the lips of knowledge. The wisdom of the prudent is to understand his way: but the folly of fools is deceit. Fools make a mock at sin: but among the righteous there is favour. 

‘Go from the presence of a foolish man, when thou perceives not in him the lips of knowledge.’ Never associate with vain, empty, ignorant men who can neither convey nor receive the truth (Matt. 7:6).

‘The wisdom of the prudent is to understand his way: but the folly of fools is deceit.’ The wisdom of the prudent is to direct his way rightly, but the folly of fools is to live deceitful lives.

‘Fools make a mock at sin: but among the righteous there is favour.’ Fools make sport of sin and live in disfavour with all who are good, but the righteous find favour.
