Thy hath done another deed.

“To be thus is nothing; But to be safely thus; our fears in Banquo.”
Banquo. Thou knew more than he appeared. This deed hath be done or the crown of Scotland was at risk. The three weird sisters told of a prophecy of Banquo fathering many crowns o’Scotland.
Banquo hath been suspicious of thy, since the deed of Duncan hath been done. An idea came into thy brain full of scorpions, that thy should hire murders and they shall do the deed. So, thy done it. Thy told thou murders that Banquo was the heavy hand hath bow’d them to thou graves and that Banquo is there enemy, as he is mine and that it was their duty to do this deed. Lady Macbeth hath no idea of this arrangement. Once Banquo hath been gone, thy hath only scotch’d the snake not kill’d it: and there remains danger in her former tooth. This danger that remains is Macduff. Macduff hath not been at thy banquet, thou hast fled to England. There is many dangers thy can feel it. Young Fleance hath escaped thou near death, and the three weird witchs prophecized Banquo birthing many crowns o'Scotland, and with Fleance free thou may be a danger to me. Thy must have thou murderers to hunt young Fleance and slaughter him, so that my throne and crown are safe.
