No living calf would have shaped itself out of the gold of these earrings, if a disaster had not occurred through an oversight of Aaron. For when Moses at the exodus of Israel from Egypt set himself to lifting the coffin of Joseph out of the depths of the Nile, he employed the following means: He took four leaves of silver, and engraved on each the image of one of the beings represented at the Celestial Throne,-the lion, the man, the eagle, and the bull.
He then cast on the river the leaf with the image of the lion, and the waters of the river became tumultuous, and roared like a lion. He then threw down the leaf with the image of man, and the scattered bones of Joseph united themselves into an entire body; and when he cast in the third leaf with the image of the eagle, the coffin floated up to the top. As he had no use for the fourth leaf of silver with the image of the bull, he asked a woman to store it away for him, while he was occupied with the transportation of the coffin, and later forgot to reclaim the leaf of silver.
This was now among the ornaments that the people brought to Aaron, and it was exclusively owing to this bull's image of magical virtues, that a golden bull arose out of the fire into which Aaron put the gold and silver.
