Act One, Scene Two
CAPTAIN ( speaking to Duncan about Macbeth fighting Macdonwald)
And fortune, on his damnèd quarrel smiling,
Showed like a rebel’s whore. But all’s too weak,
For brave Macbeth—well he deserves that name—
Disdaining fortune, with his brandished steel,
Which smoked with bloody execution,
Like valor’s minion carved out his passage
Till he faced the slave;
Which ne'er shook hands, nor bade farewell to him,
Till he unseamed him from the nave to th' chops,
And fixed his head upon our battlements.

Look like the time. Bear welcome in your eye,
Your hand, your tongue. Look like th' innocent flower,
But be the serpent under ’t. He that’s coming
Must be provided for; and you shall put
This night’s great business into my dispatch,
Which shall to all our nights and days to come
Give solely sovereign sway and masterdom.
We will speak further.
Only look up clear.
To alter favor ever is to fear.
Leave all the rest to me.

Act Four, Scene One
Second Witch:
By the pricking of my thumbs,
Something wicked this way comes.
Macbeth! Macbeth! Macbeth! Beware Macduff.
Beware the thane of Fife. Dismiss me. Enough.
Be bloody, bold, and...
