Julius Caesar Act II, Scene III
"Caesar, beware of Brutus; take heed of Cassius; come not hear Casca; have an eye to Cinna; trust not Trebonius; mark well Metellus Cimber; Decius Brutus loves thee not; thou hast wrong'd Caius Ligarius. There is but one mind in all these men, and it is bent against Caesar. If thou beest not immortal, look about you: security gives way to conspiracy. The mighty gods defend thee!" Act. II, Scene III, Line 1
The note names all of the conspirators.
