Ambiguity - literal battle, or Macbeth's battle? Also demonstrates how we cannot know the Witches' intentions - what could they gain from Macbeth? Are they on anyone's side? What is their purpose; their intent?
1.3 'There to meet with Macbeth'
1.4 'Graymalkin. / Paddock calls'
1.5 'Fair is foul, and foul is fair; / Hover through the fog and filthy air'
Proverbial at the time, but expression probably signifies the moral confusion or inversion which the Witches represent.
1.6 'killing swine'
1.7 'in a sieve I'll thither sail'
1.8 'thrice' 'the charm's wound up'
The completion of a charm that does not lead to a prophecy suggests that they may be the perpetrators of Macbeth's misfortune.

2.3 'Like valour's minion carv'd out his passage'
Again, he must carve his own passage, so he was an instrument in Duncan's murder out of incapability to be a passive observer of fate. Given a prophecy, must act upon it.
2.4 'unseam'd him from the nave to th' chops'
2.5 'worthy gentleman'
2.6 'As sparrows eagles, or the hare the lion.'

2.8 'What he hath lost, noble Macbeth hath won.'
Echoes Witches' prophecy - Demonstrates invasive nature of witches' prophecy - Rupert Goold production. Both literal battle lost and won, but more specifically Macbeth's battle is lost and won - could be used to support argument that the Witches' are to blame - they have already decided Macbeth's fate.
