Ecclesiastes 10:11-14

11If a snake bites before it is charmed, the charmer receives no fee.

12Words from the mouth of the wise are gracious, but fools are consumed by their own lips.

13At the beginning their words are folly; at the end they are wicked madness—

14and fools multiply words. No one knows what is coming— who can tell someone else what will happen after them?
