A fair request should be followed by the deed in silence.

A horrid stillness first invades the ear, And in that silence we the tempest fear.

And they three passed over the white sands, between the rocks, silent as the shadows.

Better to remain silent and be thought a fool than to speak out and remove all doubt.

But silence never shows itself to so great an advantage, as when it is made the reply to calumny and defamation, provided that we give no just occasion for them.

Even a fool, when he holdeth his peace, is counted wise.

He that refraineth his lips is wise.

He that would live in peace and at ease, must not speak all he knows, nor judge all he sees.

I have often regretted my speech, never my silence.

If you don't say anything, you won't be called on to repeat it.
