Lennox and another lord discuss politics. Lennox comments sarcastically on the recent deaths of Duncan and Banquo. He suggests that it seems implausible for Malcolm and Donalbain to be inhuman enough to kill their father. Moreover, Macbeth's slaying of the bodyguards seemed very convenient, since they probably would have denied killing Duncan. Lennox proposes that if Malcolm, Donalbain, and Fleance were in Macbeth's prison, they would also probably be dead now. He also reveals that since Macduff did not attend Macbeth's feast, he has been denounced. The lord with whom Lennox speaks comments that Macduff has joined Malcolm at the English court. The two men have apparently asked Siward to lead an army against Macbeth. Lennox and the lord send their prayers to Macduff and Malcolm.
