Ecclesiastes 10:12-15

[12] The words of a wise man's mouth win him favor,
but the lips of a fool consume him.
[13] The beginning of the words of his mouth is foolishness,
and the end of his talk is wicked madness.
[14] A fool multiplies words,
though no man knows what is to be,
and who can tell him what will be after him?
[15] The toil of a fool wearies him,
so that he does not know the way to the city.
