Tunc vadit, et assumit septem alios spiritus secum nequiores se, et intrantes habitant ibi : et fiunt novissima hominis illius pejora prioribus. Sic erit et generationi huic pessimæ.
Then he goeth, and taketh with him seven other spirits more wicked than himself, and they enter in and dwell there: and the last state of that man is made worse than the first. So shall it be also to this wicked generation.
