The king being tired with his journey, went early to bed, and in his state-room two grooms of his chamber (as was the custom) slept beside him. He had been unusually pleased with his reception, and had made presents before he retired to his principal officers; and among the rest, had sent a rich diamond to lady Macbeth, greeting her by the name of his most kind hostess.
Now was the middle of night, when over half the world nature seems dead, and wicked dreams abuse men’s minds asleep, and none but the wolf and the murderer is abroad. This was the time when lady Macbeth waked to plot the murder of the king. She would not have undertaken a deed so abhorrent to her sex, but that she feared her husband’s nature, that it was too full of the milk of human kindness, to do a contrived murder. She knew him to be ambitious, but withal to be scrupulous, and not yet prepared for that height of crime which commonly in the end accompanies inordinate ambition. She had won him to consent to the murder, but she doubted his resolution; and she feared that the natural tenderness of his disposition (more humane than her own) would come between, and defeat the purpose. So with her own hands armed with a dagger, she approached the king’s bed; having taken care to ply the grooms of his chamber so with wine, that they slept intoxicated, and careless of their charge. There lay Duncan in a sound sleep after the fatigues of his journey, and as she viewed him earnestly, there was something in his face, as he slept, which resembled her own father; and she had not the courage to proceed.
