Such was the cosmology of the ancient Jew; and his theology was equally simple. Sheol was the destined abode of all men after death, and no theory of moral retribution was attached to the conception. The rewards and punishments known to the authors of the Pentateuch and the early Psalms are all earthly rewards and punishments. But in course of time the prosperity of the wicked and the misfortunes of the good man furnished a troublesome problem for the Jewish thinker; and after the Babylonish Captivity, we find the doctrine of a resurrection from Sheol devised in order to meet this case. According to this doctrine--which was borrowed from the Zarathustrian theology of Persia--the Messiah on his arrival was to free from Sheol all the souls of the righteous, causing them to ascend reinvested in their bodies to a renewed and beautiful earth, while on the other hand the wicked were to be punished with tortures like those of the valley of Hinnom, or were to be immersed in liquid brimstone, like that which had rained upon Sodom and Gomorrah. Here we get the first announcement of a future state of retribution. The doctrine was peculiarly Pharisaic, and the Sadducees, who were strict adherents to the letter of Mosaism, rejected it to the last. By degrees this doctrine became coupled with the Messianic theories of the Pharisees. The loss of Jewish independence under the dominion of Persians, Macedonians, and Romans, caused the people to look ever more earnestly toward the expected time when the Messiah should appear in Jerusalem to deliver them from their oppressors. The moral doctrines of the Psalms and earlier prophets assumed an increasingly political aspect. The Jews were the righteous "under a cloud," whose sufferings were symbolically depicted by the younger Isaiah as the afflictions of the "servant of Jehovah"; while on the other hand, the "wicked" were the Gentile oppressors of the holy people. Accordingly the Messiah, on his arrival, was to sit in judgment in the valley of Jehoshaphat, rectifying the wrongs of his chosen ones, condemning the Gentile tyrants to the torments of Gehenna, and raising from Sheol all those Jews who had lived and died during the evil times before his coming. These were to find in the Messianic kingdom the compensation for the ills which they had suffered in their first earthly existence. Such are the main outlines of the theory found in the Book of Enoch, written about B. C. 100, and it is adopted in the Johannine Apocalypse, with little variation, save in the recognition of Jesus as the Messiah, and in the transferrence to his second coming of all these wonderful proceedings. The manner of the Messiah's coming had been variously imagined. According to an earlier view, he was to enter Jerusalem as a King of the house of David, and therefore of human lineage. According to a later view, presented in the Book of Daniel, he was to descend from the sky, and appear among the clouds.
