Ecclesiastes 10:12-15

New International Version

¹² Words from the mouth of the wise are gracious,^(A)
    but fools are consumed by their own lips.^(B)
13 At the beginning their words are folly;
    at the end they are wicked madness—
¹⁴     and fools multiply words.^(C)

No one knows what is coming—
    who can tell someone else what will happen after them?^(D)

¹⁵ The toil of fools wearies them;
    they do not know the way to town.
