O worthiest cousin, The sin of my ingratitude

Duncan
O worthiest cousin,
The sin of my ingratitude even now
Was heavy on me. Thou art so far before
That swiftest wing of recompense is slow
To overtake thee. Would thou hadst less deserved,Metaphor
That the proportion both of thanks and payment
Might have been mine! Only I have left to say,
More is thy due than more than all can pay.Hyperbaton & Ellipses

The sin of my ingratitude even now
Was heavy on me.

Macbeth
The service and the loyalty I owe
In doing it pays itself. Your Highness’ part
Is to receive our duties, and our duties
Are to your throne and state children and servants,
Which do but what they should by doing everything
Safe toward your love and honor.Anadiplosis
Duncan
Welcome hither.
I have begun to plant thee and will labor
To make thee full of growing.Metaphor—Noble Banquo,
That hast no less deserved nor must be known
No less to have done so, let me enfold thee
And hold thee to my heart.
Banquo
There, if I grow,
The harvest is your own.Metaphor
Duncan
My plenteous joys,
Wanton in fullness, seek to hide themselves
In drops of sorrow.—Sons, kinsmen, thanes,
And you whose places are the nearest, know
We will establish our estate upon
Our eldest, Malcolm, whom we name hereafter
The Prince of Cumberland; which honor must
Not unaccompanied invest him only,
But signs of nobleness, like stars, shall shine
On all deserversSimile.—From hence to Inverness
And bind us further to you.
Macbeth
The rest is labor which is not used for you.
I’ll be myself the harbinger and make joyful
The hearing of my wife with your approach.Hyperbaton
So humbly take my leave.
Duncan
My worthy Cawdor.
Macbeth, aside
The Prince of Cumberland! That is a step
On which I must fall down or else o’erleap,
For in my way it lies.Metaphor Stars, hide your fires;
Let not light see my black and deep desires.
SynecdocheThe eye wink at the hand, yet let that be
Which the eye fears, when it is done, to see.Personification
