Be innocent of the knowledge, dearest chuck,
Till thou applaud the deed.
SHAKS.: _Macbeth,_ Act iii., Sc. 2.

Thou wilt not utter what thou dost not know;
And so far will I trust thee.

Is like a wild bird put into a cage,
Whose door no sooner opens, but 't is out.
BEN JONSON: _Case is Altered,_ Act iii., Sc. 3
