Point out an example of dramatic irony in this scene?

Example One:

Macbeth plans to murder Duncan in his home at Inverness.

Stars, hide your fires!

Let not light see my black and deep desires;

The eye wink at the hand; yet let that be,

Whic the eye fears, when it is done, to see.

All while Duncan praises Macbeth's honor......

True, worthy Banquo: he is full so valiant,

And in his commendations I am fed;

It is a banquet to me. Let's after him,

Whose care is gone before to bid us welcome:

It is a peerless kinsmen.
