Example 1:
There's one did laugh in 's sleep, and one
cried 'Murder!"
That they did wake each other: I stood and heard them;
But they did say their prayers, and address'd them
Again to sleep
Act II, Scene 2- Macbeth
Summary: Macbeth is telling what he had heard as he passes a bedroom on the way back from Duncan's room.
Comment: In this case, "blood" is referring to murder because with murder comes bloodshed.
Example 2:
Who was it that thus cried? Why,
worthy thane
You do unbend your noble strength to think
So brainsickly of things. Go get some water,
And wash this filthy witness from your hand.
Why did you bring these daggers from the place?
They must lie there: go carry them, and smear
The sleepy grooms with blood.
Act II, Scene 2- Lady Macbeth
Summary: Lady Macbeth is asking Macbeth who he heard crying murder. She doesn't believe Macbeth that there was really someone that was crying murder then she tells him to go get some water and wash the blood off of his hands and then she wonders why he has daggers.
Comment: In this case, "blood" refers to the blood on the daggers that Macbeth has and Lady Macbeth wants him to smear it on the grooms.
Example 3:
Whence is that knocking?
How is 't with me, when every noise appals me?
what hands are here! Ha! they pluck out mine eyes.
Will all great Neptune's ocean wash this blood
Clean from my hand? No, this my hand will rather
The multitudinous seas incarnadine,
Making the green one red.
Act II, Scene 2- Macbeth
Summary: Macbeth is wondering why every noise appeals to him and if the ocean will wash his hands clean of blood. He thinks not and that his bloody hands will turn the ocean red instead.
Comment: In this case, "blood" is referring to the color red in which Macbeth will change the ocean to that color with all of the blood that is on his hands.
