Some of the language of this scene is difficult. Its lines are full of pauses, half-spoken thoughts, and fragments of reported speech. Its function is twofold: first to convince the audience of Lennox's real thoughts about Macbeth. Even though Lennox appears loyal to Macbeth at the end of Act IV, Scene 1, here he divulges his concerns in lines such as "Men must not walk too late" and, more directly, the phrase "the tyrant's feast."
The primary function of the other lord is to confirm the news of Macduff's flight to England and to introduce the names of other rebel leaders, Northumberland and Siward, who will combine against Macbeth in the final act. But his words "That . . . we may again / Give to our tables meat, sleep to our nights" (32–34) also recall, ironically, the words of Macbeth to his wife in Act III, Scene 2: "But let the frame of things disjoint . . . / Ere we will eat our meal in fear, and sleep / In the affliction of these terrible dreams."
