Julius Caesar, Act III, Scene I
. . .

CINNA: O Caesar -

CAESAR: Hence! Wilt thou lift up Olympus?

DECIUS: Great Caesar -

CAESAR: Does not Brutus bootless kneel?

CASCA: Speak, hands, for me!

[CASCA stabs CAESAR in the neck. CAESAR catches hold of his arm. He is then stabbed by several other conspirators, and at last by MARCUS BRUTUS].

CAESAR: Et tu, Brute? -- Then fall, Caesar!
[Dies. The Senators and People retire in confusion.]
CINNA: Liberty! Freedom! Tyranny is dead! Run hence, proclaim, cry it about the streets.
