Ecclesiastes 10:10-15

10If the ax is dull and its edge unsharpened, more strength is needed, but skill will bring success.

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?

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