uilt -- right through their door. Now Macbeth wonders why he couldn't say "amen" to the "God bless us" that he heard. Lady Macbeth tells her husband that he'll drive them both crazy if he keeps thinking like that, but he says, "Methought I heard a voice cry 'Sleep no more! / Macbeth does murder sleep'" (2.2.32-33). Now his mind has made a very large leap, not just a jump. This "voice" is a pure hallucination, just as the "dagger of the mind" was. He praises sleep as innocence, as the one sure relief from all of life's problems, but seems sure that he -- who murdered an innocent man in his sleep -- will never sleep again. His wife asks, "Who was it that thus cried?"

She tells him to "Go get some water, / And wash this filthy witness from your hand" (2.2.43-44). The "filthy witness" is the blood of Duncan, which acts as a witness to Macbeth's crime, but as Lady Macbeth is saying this, she sees another "witness": Macbeth is still carrying the grooms' daggers! She tells him he must take the daggers back, put them with the grooms, and smear the grooms with blood, so it will look like the grooms killed the King.

Now Lady Macbeth is scornful of her husband. She takes the daggers from him and tells him that it's childish to be afraid of the sleeping or the dead. And she's not afraid of blood, either. She says, "If he [King Duncan] do bleed, / I'll gild the faces of the grooms withal / For it must seem their guilt" (2.2.52-54). With these bitter words, she goes to finish her husband's job for him. As soon as Lady Macbeth has exited, we hear a knocking. Macbeth hears ...
