Answer:
Explanation:
She is really giving him the gears.
He cannot bear the thought of going into Duncan's chamber again, for there lies Duncan murdered in his bed -- a scene that gives Macbeth a terrible feeling.
So lady Macbeth says give me the daggers. Almost as an aside she says the the sleeping and the dead surely resemble each and it is the eyes of childhood that fear the devil (whom I believe was seen as red).
She goes on to say that if Duncan is bleeding, she's going to smear the grooms (attendants) with his blood so that they look all the more guilty.
One writer proposes that there is a pun in the word gild (which is gold which in Shakespeare's time was seen as red). She's saying that the red appears like red gold. Think about that bit of irony for a moment. I think she is suggesting that the good that gold can do is shadowed by the evil that it does. Concentrate on the joke she utters. She's calm cool and collected enough to make a joke, poor though it may be.
The point of the remark is that not only is Lady Macbeth in control, she is able at this point to joke about it. Contrast that with Macbeth who is starting to go mad from the thoughts of the crime he has committed. Quite a bit is made about the knocking. Is it real or is it in his mind? At this point we don't know.
