Macbeth Act 4 Comprehension Questions

Macbeth goes to find the Weird Sisters. They agree to show him what the future has in store. Macbeth has three visions. An armed head tells Macbeth to “beware Macduff.” A bloody child tells Macbeth t”none of woman born / Shall harm Macbeth.” A child wearing a crown and holding a tree tells Macbeth that: “Macbeth shall never vanquish’d be until / Great Birnam wood to high Dunsinane hill / Shall come against him.”
Macbeth is satisfied by the prophecies. Still, he develops a plan for Macduff. Macbeth plans to “make assurance double sure” and kill Macduff. As for the woods vanquishing him, Macbeth says: “That will never be / Who can impress the forest, bid the tree / Unfix his earth-bound root?”
Macbeth still wonders about Banquo’s prophecy. What he sees bothers him. The Weird Sisters summon a vision of eight kings. The kings pass over the stage in order; the last holding a glass. Banquo’s ghost follows behind them.
Macduff leaves his family, which bothers his wife. While he’s away, Macbeth’s plan is set in motion. A messanger arrives and tells Lady Macduff: “If you will take a homely man’s advice, / Be not found here.” Lady Macduff hesitates and shortly thereafter, the murderers arrive and kill her son and her.
Macduff finds Malcolm, who is distrusting of him. He reminds Macduff that Macbeth was once thought good as well. Malcolm tells Macduff: “This tyrant, whose sole name blisters our tongues, / Was once thought honest: you have loved him well.”
Ross comes from Scotland with the horrible news. Macbeth has murdered Macduff’s family. Malcolm advises Macduff to use this news as “the whetstone of your sword: let grief / Convert to anger; blunt not the heart, enrage it.”
