Or tutti sorgete,  Lady Macbeth's aria from Macbeth

Or tutti sorgete, ministri infernali,		And now all you, infernal ministers, rise up,
Che al sangue incorate, spingete i mortali!	you who thrust and urge the mortals to blood!
Tu, notte, ne avvolgi di tenebra immota;	You, night, wrap us in motionless darkness;
Qual petto percota non vegga il pugnale		the dagger doesn't see which breast it strikes!
