When, upon a day, there came a messenger to him, pale and shaking with fear, almost unable to report that which he had seen; for he averred, that as he stood upon his watch on the hill he looked toward Birnam, and to his thinking the wood began to move! “Liar and slave!” cried Macbeth. “If thou speakest false, thou shalt hang alive upon the next tree, till famine end thee. If thy tale be true, I care not if thou dost as much by me”; for Macbeth now began to faint in resolution, and to doubt the equivocal speeches of the spirits. He was not to fear till Birnam wood should come to Dunsinane; and now a wood did move! “However,” said he, “if this which he avouches be true, let us arm and out. There is no flying hence, nor staying here. I begin to be weary of the sun, and wish my life at an end.” With these desperate speeches he sallied forth upon the besiegers, who had now come up to the castle.
