Why, worthy thane

You do unbend your noble strength, to think

So brain-sickly of things:—go, get some water,

And wash this filthy witness from your hand.—

Why did you bring these daggers from the place?

They must lie there. Go. Carry them; and smear

The sleepy grooms with blood.

Mac. I’ll go no more;

I am afraid to think on what I have done.

Look out again I dare not.
