Ecclesiastes 10:11-15

11If the snake bites before it is charmed, there is no profit for the charmer.

12Words from the mouth of the wise are gracious, but the lips of a fool destroy him.

13The words from his mouth begin as folly and end as grievous madness—

14and the fool multiplies words. No one knows what will happen, and who can tell him what will happen after him?

15The mischief of fools wearies them for he doesn’t know how to go to town.
