So, taking the dagger in his hand, he softly stole in the dark to the room where Duncan lay; and as he went he thought he saw another dagger in the air, with the handle toward him, and on the blade and at the point of it drops of blood; but when he tried to grasp at it it was nothing but air, a mere phantasm proceeding from his own hot and oppressed brain and the business he had in hand. Getting rid of this fear, he entered the king’s room, whom he despatched with one stroke of his dagger. Just as he had done the murder one of the grooms who slept in the chamber laughed in his sleep, and the other cried, “Murder,” which woke them both. But they said a short prayer; one of them said, “God bless us!” and the other answered, “Amen”; and addressed themselves to sleep again. Macbeth, who stood listening to them, tried to say “Amen” when the fellow said “God bless us!” but, though he had most need of a blessing, the word stuck in his throat and he could not pronounce it.
