Explanations on Macbeth (III.iv.) quotes...?

Question

There's a few quotes that I'm supposed to "explain the significance of" for an English assignment, but I do not understand:

1) "It will have blood..."

2) "Stones have been known to move and trees to speak. Augures, and understood relations, have by maggot-pies, and choughs, and rooks brought forth the secret'st man of blood. What is the night?"

3) "I hear it by the way, but I will send. There's not a one of them but in his house I keep a servant feed."

4) "I will tomorrow - and betimes I will - to the weird sisters. More shall they speak. For now I am bent to know by the worst means, the worst; for mine own good, all causes shall give way. I am in blood stepped in so far that should I wade no more, returning were as tedious as go o'er. Strange things I have in head that will to hand, which must be acted ere they may be scanned."

5) "Come, we'll to sleep. My strange and self-abuse is the initiate fear that wants hard use; we are yet but young in deed."

Answer 1

1. Statement saying that he will have revenge, in this case, the death of someone.

2. He's speaking of the supernatural and bad things happening, so why should he be afraid of the night? He's saying that the fear of the night is not important to him.

3. He has someone in the house that works for him? That one I don't know.

4. He will return to the witched the next day. He is afraid because of the murder he has made and worried about it.

5. Fear over an upcoming event. They have worried a good deal before even doing what they are thinking of.
