I do the wrong and first begin to brawl

Richard
I do the wrong and first begin to brawl.
The secret mischiefs that I set abroach
I lay unto the grievous charge of others.

And thus I clothe my naked villainy
With odd old ends stol’n forth of Holy Writ,
And seem a saint when most I play the devil.

Clarence, who I indeed have cast in darkness,
I do beweep to many simple gulls,
Namely, to Derby, Hastings, Buckingham,
And tell them ’tis the Queen and her allies
That stir the King against the Duke my brother.
Now they believe it and withal whet me
To be revenged on Rivers, Dorset, Grey;
But then I sigh and, with a piece of scripture,
Tell them that God bids us do good for evil;
And thus I clothe my naked villainy
With odd old ends stol’n forth of Holy Writ,
And seem a saint when most I play the devil.
   Enter two Murderers.
But soft, here come my executioners.—
How now, my hardy, stout, resolvèd mates?
Are you now going to dispatch this thing?
Murderer
We are, my lord, and come to have the warrant
That we may be admitted where he is.
