Macbeth Quote Help?

Question

I need to have who said it and to whom it was said to. I also need an explanation of the quote. Any help is appreciated

"To be thus is nothing, But to be safely thus. Our fears in Banquo stick deep, and in his royalty of nature Reigns that which would be feared.

Answer 1

It is from the play Macbeth by William Shakespeare.

Macbeth is the one who said that quote.

Here, Macbeth, having killed the king, contemplates killing his friend, Banquo.

Macbeth: To be thus is nothing, but to be safely thus--

Our fears in Banquo stick deep,

And in his royalty of nature reigns that

Which would be feared. 'Tis much he dares;

And to that dauntless temper of his mind

He hath a wisdom that doth guide his valour

To act in safety. There is none but he

Whose being I do fear; and under him  

My genius is rebuked, as it is said

Hope that helps!

Answer 2

Act III, Scene i, lines 48-50. Macbeth is speaking to himself. It is a soliloquy. He is brooding about what he has done in killing Duncan. He feels unsafe ("but" means "unless"). It is no good being king except if one is secure in that position, and since Banquo is by nature royal, as Macbeth is not, Macbeth fears that Banquo poses a threat. There is no rational cause for Macbeth to feel so; Banquo nowhere manifests the desire to do the sort of deed Macbeth has done, but Macbeth does not know that, and, moreover, not having done murdered Duncan wholly willingly (his wife had to push him into it), and thinking that he could also be murdered, projects his fears onto Banquo. This is an early stage of his paranoia.
