Ecclesiastes 10:13-15

King James Version

¹³ The beginning of the words of his mouth is foolishness: and the end of his talk is mischievous madness.

¹⁴ A fool also is full of words: a man cannot tell what shall be; and what shall be after him, who can tell him?

¹⁵ The labour of the foolish wearieth every one of them, because he knoweth not how to go to the city.
