What are some examples of juxtaposition in Macbeth?

Macbeth's violence in 1:2 and Lady Macbeth's separation in 1:7. Macbeth is filled with contrasts, including the juxtaposition of Macbeth's and Banquo's reaction to the witches. Juxtaposition was also used to compare between Macbeth's ambition and Lady Macbeth's ambition. Macbeth is juxtaposed with the fifth scene of Act 1 because they both take place in palaces. But the fourth scene began at king Duncan's palace and the fifth scene begins in Macbeth's palace but both scenes take place in palaces.
