In Act 5 Scene 4 of Shakespeare's "Macbeth," Macbeth makes the statement, "They have tied me to a stake; I cannot fly, but bear-like I must fight the course. What's he that was not born of woman? Such a one am I to fear, or none" (lines 27-31). Macbeth is expressing his belief that he is invincible in battle because he has been told by the witches that no man born of woman can harm him. Therefore, he is confident that he will emerge victorious even against the larger and better-equipped army of Malcolm and Macduff.
Macbeth's statement about the opposing troops dying of hunger reflects his overconfidence and delusion. He is so convinced of his invincibility that he believes even the natural elements, such as hunger, will work in his favor. He thinks that the enemy soldiers will become weak and vulnerable without food, which will give him an advantage in battle. This belief shows how Macbeth's arrogance and ambition have clouded his judgment and caused him to underestimate his opponents.
