As who should say, “i am Sir Oracle,
And when I ope my lips, let no dog bark!”
O! my Antonio, I do know of these
That therefore are reputed wise
For saying nothing, when, I am sure,
If they should speak, would almost dam those ears,
Which, hearing them, would call their brothers fools.
The Merchant of Venice -- I. 1.
