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." Again Moses looked, and he beheld a spring of living water welling up from under the tree of life and dividing into four streams, which passed under the throne of glory, and thence encompassed Paradise from end to end. He also saw four rivers flowing under each of the thrones of the pious, one of honey, the second of milk, the third of wine, and the fourth of pure balsam. Beholding all these desirable and pleasant things, Moses felt great joy, and he said, "Oh, how great is Thy goodness, which Thou hast laid up for them that fear Thee, which Thou hast wrought for them that put their trust in Thee, before the sons of men!" And Moses left Paradise, and returned to the earth. At the moment of his departure, a heavenly voice cried aloud: "Moses, servant of the Lord, thou that art faithful in His house, even as thou hast seen the reward that is laid up for the pious in the world to come, so also thou wilt be worthy of seeing the life of the world that shall be in the future time. Thou and all Israel, ye shall see the rebuilding of the Temple and the advent of the Messiah, behold the beauty of the Lord, and meditate in His Temple."[118] In the world to come Moses, beside sharing the joys of Israel, will continue his activity as the teacher of Israel, for the people will go before Abraham and request him to instruct them in the Torah. He will send them to Isaac, saying, "Go to Isaac, he hath studied more of the Torah than ever I studied," but Isaac, in turn, will send them to Jacob, saying, "Go to Jacob, he hath had more converse with the sages than ever I had." And Jacob will send them to Moses, saying, "Go to Moses, he was instructed in the Torah by God Himself."[119] In the Messianic time, Moses will be one of the seven shepherds that shall be the leaders of Israel with the Messiah.[120]
