And if he said, “What is the nature of this water?” they at once run after him, stoning him, and saying to him, “Wretch, are thou not of the seed of them that kissed the [golden] calf, and art unfit to see the King and His throne in his beauty.” And if he be such, a voice goeth forth from the seventh heaven saying, “well have ye said [that] he is from the seed of them that kissed the [golden] calf and is not fit to see the King and His throne.” He does not move from the spot before they place on him a thousand thousands of pieces of iron.
