At the beginning of the scene when Lady Macbeth is reading the
letter from her husband, Macbeth confides in her the unusual
encounter he has just experienced with the witches. Macbeth
completely trusts his wife and tells her every detail, even that
the witches had hailed him to be a future king. At the end of
the letter, Macbeth reminds his ‘Dearest partner of greatness’
to be excited and ‘rejoice’ ‘what greatness is promised thee’.
After Lady Macbeth learns of the witches promises, she believes
that she and her husband will have to assassinate Duncan in
order for the prophesy to be fulfilled. She asks to be rid of
any feelings of remorse and femininity to make the deed easier.
When Macbeth enters, Lady Macbeth greets him with praise and
love, by informing him that his letters to her ‘have transported
me beyond this ignorant present’ Macbeth immediately returns the
gesture of love by addressing her as ‘My dearest love’. This
exchange emphasizes the loving, understanding relationship that
the Macbeths are in.
