Who ever answers this gets 93 points!!! In this excerpt from act III of Shakespeare’s Macbeth, which rhetorical device is used in the underlined words?

MACBETH:
It will have blood; they say, blood will have blood:
"Stones have been known to move, and trees to speak;"

By maggot-pies, and coughs, and rooks, brought forth
The secret'st man of blood.—What is the night?
(act III, scene IV)

The sentence in parenthesis is supposed to be the underlined sentence
