Read it through once

TITUS. Do me some service ere I come to thee. Lo, by thy side where Rape and Murder stands; Now give some surance that thou art Revenge: Stab them, or tear them on thy chariot wheels, And then I’ll come and be thy waggoner, And whirl along with thee about the globe. Provide thee two proper palfreys, black as jet, To hale thy vengeful waggon swift away, And find out murderers in their guilty caves. And when thy car is loaden with their heads, I will dismount, and by the waggon-wheel Trot like a servile footman all day long, Even from Hyperion’s rising in the east Until his very downfall in the sea. And day by day I’ll do this heavy task, So thou destroy Rapine and Murder there.
