Ecclesiastes 10:3

Even when a fool walks along the road he lacks sense, and shows everyone what a fool he is.

Every shrewd person acts with knowledge, but a fool displays his folly.

A fool takes no pleasure in understanding but only in disclosing what is on his mind.

The lips of a fool enter into strife, and his mouth invites a flogging.

Just as dreams come when there are many cares, so the rash vow of a fool occurs when there are many words.

So they are astonished when you do not rush with them into the same flood of wickedness, and they vilify you.

Even a fool who remains silent is considered wise, and the one who holds his tongue is deemed discerning.
