Ecclesiastes 10:11-15

11If a snake bites before you charm it, what’s the use of being a snake charmer?

12Wise words bring approval, but fools are destroyed by their own words.

13Fools base their thoughts on foolish assumptions, so their conclusions will be wicked madness;

14they chatter on and on. No one really knows what is going to happen; no one can predict the future.

15Fools are so exhausted by a little work that they can’t even find their way home.
