With the advent of post-Exilic Judaism (Ezra and after), including its emphasis on law and cult, there was not much room left for prophecy. The prophetic heritage was channelled through the teaching of their words. What remained of prophetic activity was expressed in various literary works that claimed esoteric knowledge of the divine purpose. The apocalyptic writers saw themselves as taking over and carrying on the prophetic task, but they went beyond the prophets in their use of old mythological motifs. The events they described had usually occurred long ago, but their recounting of those events was for the purpose of hinting and even predicting the events of the future. There was a far greater emphasis upon predictive speculation about the future than on the prophetic analysis and insight into history. The apocalyptic authors wrote pseudonymously, using the names of ancient worthies (such as Adam, Enoch, Abraham, Daniel, and Ezra). The literature is predominantly prose, but that of the classical prophets was predominantly poetry. Apocalyptic language is lavish in its use of fantastic imagery, frequently using riddles and numerical speculations. In apocalyptic literature angelology came into full blossom, with accounts of fallen angels (fallen stars) caught up in the forces opposed to God, frequently pictured in the old mythological motif of the struggle between darkness and light. Wild beasts symbolized peoples and nations, and there were esoteric calculations and speculations about the different eras through which history was passing as the world approached the eschaton (the consummation of history).

Dominant in apocalyptic literature is the theme of God’s sovereignty and ultimate rule over all the universe. The message of the apocalyptic writers is one of both warning, of the doom to come at the end of history, and hope in the new age beyond history under the rule of God, when the righteous will be vindicated.

Prophecy and prophetic religion in postbiblical Judaism

Though prophecy did not cease functioning in early Judaism, rabbinical Judaism—that influenced by rabbis, scholars, and commentators of the Bible—sought to limit it by advocating the pre-Exilic era as the classical time of prophecy. Prophecy was not suppressed, but it came to be encircled by the Torah (the first five books of the Hebrew Bible) in that all prophecy had to be in harmony with Torah, which was the definitive revelation of God’s will. Thus, rabbinical Judaism gave prophecy its place of importance, but only as a phenomenon of the past. Such a theological stricture could not restrain the charismatic, eschatologically oriented patriots who arose during the time of Roman hegemony (mid-1st century bce–4th century ce). One rabbi, Akiba ben Joseph, joined with a messianic pretender, Bar Kokhba (originally Simeon ben Koziba) in a revolt (132–135) and functioned as a prophet within that movement.

Some prophets are known from the period of Hellenistic Judaism. Chapter 14 of the First Book of Maccabees relates that Simon Maccabeus, who finally secured political independence for Judaea in 142 bce, was chosen as “leader and high priest forever, until a trustworthy prophet should arise.” The same notion of a prophet soon to appear is expressed in chapter 1 of First Maccabees . The Hasmonean (Maccabean) prince John Hyrcanus I (reigned 135/134–104 bce) was regarded as fulfilling those expectations and was called a prophet by the 1st-century-ce Jewish historian Flavius Josephus, better known as Josephus. Josephus also mentions some Zealots (Jewish revolutionaries) as prophets and also one Jesus, son of Ananias, who in 62 ce predicted the destruction of the Temple and the defeat of the Jews. Josephus also mentions the seer Simon, a prophet leader (Antiquities), and Menahem, who prophesied in the 1st century bce. Among the followers of Judas Maccabeus, the leader of the 2nd-century-bce revolt, there apparently were persons who divined knowledge of the future. Those and other notations indicate that seers and prophets played an important role in the intertestamental and postbiblical periods.

Jewish theology in Alexandria (Egypt) took up early rabbinical ideas and postulated that the will of God was to be discerned in the Torah and affirmed that the interpretation of law succeeded both the prophetic office and the role of sages. The law was thus considered to be superior to prophetic teaching. The Jewish philosopher Philo Judaeus (flourished 1st century ce) affirmed that the Jews are a people of prophets. He also asserted that when a prophet has reached the fourth and final stage of ecstasy, he is ready to become an instrument of divine power. Though Philo was influenced by Hellenistic concepts of prophecy, his basic foundation was still the Hebrew Bible. Later rabbis believed that prophecy, though it was a gift from the world beyond, still required some knowledge. In rabbinic discussions of the nature of truth, it was generally held that reason alone was necessary but insufficient; prophecy could supply what was missing.

The medieval Jewish philosopher Moses Maimonides (1135–1204) understood prophecy as an emanation from God to the intellect of man. Thus, prophecy could not be acquired by human effort. The divine gift of prophecy was bestowed upon those with both mental and moral perfection, combined with the presence of superior imagination. Opponents of that view advocated that Maimonides’ concept of prophecy was not Jewish, because Jewish prophecy always showed itself to be miraculous.
