When God created the world the lower waters of the abyss tried to ascend to the heavens. So He made a stone, engraved thereon His Holy Name in 48 different forms, and stopped therewith the mouth of the abyss. When David laid the foundation of the Temple he dug the earth 15,000 cubits deep when he reached that very stone. Not knowing what it really was he tried to remove it, when a voice said, "Beware lest thou destroy the world, for the waters will flood it." He did not heed the voice, but dug up the stone; the engraved Name disappeared and the stone became like a clod of earth in his hands and the waters began to mount up. David prayed but he was not heard, and
then he said, “If anyone is here who knows how to write the Ineffable Name and refuses to do so, may he die by hanging/' Ahitophel wrote the Name, the waters then returned to their former place, the stone was again replaced in its former position and this is the foundation stone of the world and the Temple.
