Help! Macbeth! When does...?

Question: Help! Macbeth! When does!.!.!.!?

I'm trying to connect something to this specific part in Macbeth!. Macbeth asks someone, I think it's Macduff, to follow him in his plans/go along with his pursuits/agree with him (something along those lines) and Macduff responds that he will as long as it is right/true/good (something along those words)!. Which scene is that or around which part!? Or is it not Macduff and Macbeth at all!? I can't remember! I read it last year!.Www@QuestionHome@Com

I think this is what you're referring to:

All's well!.
I dreamt last night of the three weird sisters:
To you they have show'd some truth!.

MACBETH
I think not of them:
Yet, when we can entreat an hour to serve,
We would spend it in some words upon that business,
If you would grant the time!.

BANQUO
At your kind'st leisure!.

MACBETH
If you shall cleave to my consent, when 'tis,
It shall make honour for you!.

BANQUO
So I lose none
In seeking to augment it, but still keep
My bosom franchised and allegiance clear,
I shall be counsell'd!.
