Ecclesiastes 10
11 Ref If a snake gives a bite before the word of power is said, then there is no longer any use in the word of power.
12 Ref The words of a wise man's mouth are sweet to all, but the lips of a foolish man are his destruction.
13 Ref The first words of his mouth are foolish, and the end of his talk is evil crime.
14 Ref The foolish are full of words; man has no knowledge of what will be; and who is able to say what will be after him?
