Silence is a fence around wisdom.

The silence of a treacherous man is to be feared even more than his words.

Even silence speaks.

If a word be worth one shekel, silence is worth two.

Silence was never written down.

To silence another, first be silent yourself.

Repentance for silence is better than repentance for speaking.

Silence betokens consent.

Silence is golden; speech is silver.

Beware of a man that does not talk and a dog that does not bark.
