'A little water clears us of this deed'
Embedded and contextualised example: When she returns from incriminating the chamberlains, Lady Macbeth claims, in contrast to Macbeth’s metaphor about Neptune’s oceans, that “a little water clears [them] of this deed”.
The juxtaposition of this line with Macbeth’s line (above) conveys the early difference between the two when it comes to guilt and remorse
The adjective “little” used to further diminish the significance of the regicide - it doesn’t even need much water
The irony that this line later evokes given how much guilt and remorse Lady Macbeth goes on to feel, evidence in Act 5 Scene 1
The symbolic use of water as cleansing people of sin - linking to Christian ideas of baptism
