Ecclesiastes 10:14 in the King James Version
A fool also is full of words: a man cannot tell what shall be; and what shall be after him, who can tell him?
Context
13 The beginning of the words of his mouth is foolishness; and the end of his talk is mischievous madness.
14 A fool also multiplies words. Man doesn’t know what will be; and that which will be after him, who can tell him?
15 The labor of fools wearies every one of them; for he doesn’t know how to go to the city.
