The leaders of the congregation used to carry the Scroll of the Law whenever they went to meet the king. After a time they only carried the empty ornamented case and an apostate denounced them. A heavenly voice warned the beadle and ordered him to put the Scroll in the case. The king paid them a visit, was met as usual, the case was opened and the scroll was discovered inside.
