Read it through once

DUKE. The contents of this is the return of the Duke; you shall anon over-read it at your pleasure, where you shall find within these two days he will be here.

Look, th’ unfolding star calls up the shepherd. Put not yourself into amazement how these things should be. All difficulties are but easy when they are known. Call your executioner, and off with Barnardine’s head. I will give him a present shrift, and advise him for a better place. Yet you are amazed; but this shall absolutely resolve you. Come away; it is almost clear dawn.
