Moses asked Shamshiel about the size of Paradise, but not even he who is the prince thereof could answer the question, for there is none that can gauge it. It can neither be measured nor fathomed nor numbered. But Shamshiel explained to Moses about the thrones, that they were different one from the other, some being of silver, some of gold, some of precious stones and pearls and rubies and carbuncles.
The thrones made of pearls are for the scholars that study the Torah day and night for her own sake; those of precious stones are for the pious, those of rubies for the just, those of gold for the repentant sinners, and those of silver for the righteous proselytes. "The greatest of them all," continued Shamshiel, "is the throne of Abraham, the next in size the thrones of Isaac and Jacob, then come the thrones of the prophets, the saints, and the righteous, each in accordance with a man's worth, and his rank, and the good deeds he has performed in his lifetime."
Moses asked then for whom the throne of copper was intended, and the angel answered, "For the sinner that has a pious son. Through the merits of his son he receives it as his share."
