'Fool's' in the Bible

It is a fool's pleasure to do wickedness, but wisdom is a man of understanding's pleasure.

The fool's talk brings a rod to his back, but the lips of the wise protect them.

A fool's lips come into strife, and his mouth invites beatings.

A fool's mouth is his destruction, and his lips are a snare to his soul.

A stone is heavy, and sand is a burden; but a fool's provocation is heavier than both.
