Macbeth Soliloquy
“Thou marshall’st me the way that I was going And such an instrument I was to use.”
Macbeth here is saying the dagger is going to guide and lead him to kill King Duncan and he is also saying that the dagger he sees he wants to make it his weapon of choice to kill King Duncan. This is the point weere Macbeth is hallucinating imaging a dagger and he wants this dagger of his imagination to guide him to where he needs to go and he wants to make this dagger his weapon of choice since it is encouraging him to do it.
