MACBETH: Now the fever of fear comes again...otherwise I would have been perfect! Solid as marble, firm as rock, free as the air itself, but now I am cramped, enclosed, confined by my doubts and fears... but Banquo is secured?
FIRST MURDERER: Yes, my good lord. Secured in a ditch, with twenty deep gashes in his head, each one a certain death.
MACBETH: Thanks for that. The grown serpent lies there dead—but the young worm that escaped will breed his venom, given time, but for now he has no fangs.
Get thee gone. Tomorrow we will speak with you again.
