Ecclesiastes 10:3

King James 2000

Yea also, when he that is a fool walks by the way, his wisdom fails him, and he says to every one that he is a fool.

See the chapter Copy

A fool has no delight in understanding, but that his heart may express itself.

Every prudent man deals with knowledge: but a fool lays open his folly.

In which they think it strange that you run not with them to the same excess of dissipation, speaking evil of you:

For a dream comes through much business; and a fool's voice is known by a multitude of words.

A fool's lips enter into contention, and his mouth calls for blows.
