The first apparition, "an Armed Head," a disembodies head wearing a helmet, tells Macbeth, "Beware Macduff; / Beware the Thane of Fife" (4.1. 79–80).

What scene is Beware Macduff?

First Apparition: Macbeth! Macbeth! Macbeth! beware Macduff., Act IV, Scene 1, Macbeth.

When did the witches say beware Macduff?

Macbeth receives this warning from an apparition conjured by the witches in Act IV, Scene 1. The apparition, an "armed head," warns Macbeth to "beware the Thane of Fife." Two more apparitions, however, give prophecies that seem to contradict the first.
