Prove that Macbeth is adept at playing the hypocrite

Macbeth gives Duncan all kinds of complements and pledges his undying loyalty while planning to kill him at the same time.

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.
