The disaster of the Exile is charged by the Prophets to the unrepented sins of the nation, and while this is a religious interpretation it is not unsupported by a review of the history. The people had set their hearts upon a glorious kingdom of material prosperity, presided over and protected by a mighty national deity; the Prophets wanted a kingdom of righteousness, which would reflect the character of Jehovah and be a witness to the nations of His reality and power. While they saw in the Exile a calamity which meant the destruction of the nation, and an evidence that Jehovah had broken His covenant because of disobedience, they clung to the belief that the end for which Jehovah had chosen Israel might still be attained. That nation might be destroyed, yet from its ruins there would arise a Kingdom of God; a remnant would return, weaned from a false religion, to work out a new ideal of holiness and service.
The period which follows is one of great obscurity and the records which are actually dated from this time are scanty. Literary criticism however throws great light on this period because it believes that it is from the Exile that we are to date many institutions and writings that have been referred to a previous age. This may seem at first sight a desperate device, since so little is known of the actual conditions; and yet unfettered investigation can arrive at no other conclusion, the exilic stamp being often unmistakable and even showing itself in geographical outlook (1 Kings iv. 24). If we take the Bible as it stands, it presents us with the story of an early legislation given by Moses, neglected however by the entire people, including the Reformers and Prophets, until it suddenly appears after the Exile as the acknowledged code for the regulation of religion and common life. It would be quite possible to conceive that the shock of the Exile drove the Jews to examine the details of the neglected covenant of Jehovah and to restore the authority of the Law of Moses. Such however is impossible, not only from that fact that there is no mention of the Law of Moses in the records that can be dated between the Conquest of Canaan and the Exile, but that in this period we can discern customs and ideas gradually growing up that find their full and final embodiment in the Pentateuch as we now possess it. From the lawless condition of the Judges and the early monarchy, we advance to the teaching of the Prophets. It is Isaiah who contributes the ideas which lie at the basis of the Deuteronomic Code, and the time of Josiah is the first to show the influence of that code. Ezekiel is the first to show any trace of the ideas which we find embodied in Leviticus, but these, as we shall see, have to be explained as anticipations of, rather than as an acquaintance with, the finished Levitical Code.
When we consider what effect the Exile would have upon the more thoughtful of the Jews, we can imagine that conscience would be shocked into activity, and a new interest would be taken in their strange history, especially in its prophetic interpretation. It is common in history to find that repentance rarely goes so deep as to grasp the inner meaning of its discovered sin, but is apt to content itself with somewhat superficial methods of showing its sincerity and securing future compliance with religion. So at least, the records of Israel's history assure us, happened in this instance, and one of the resolutions of their penitence took concrete form in the writing or editing of their history so that it should be a warning to the future, and in codifying customs and drawing up regulations which should make apostasy for ever impossible. Many references in the ancient records or in the oral tradition which savoured of idolatry or of a too anthropomorphic conception of God were corrected, as those references, the tendency of which was not detected, have remained to bear witness; and the whole history was fitted somewhat clumsily into a mechanical scheme, which was rather what they thought ought to have happened than what really did happen. One example of this may be seen in the condemnation which is naïvely passed on king after king because he had allowed sacrifice to be made at the high places; the fact being that this was not made illegitimate until the reign of Josiah. In this way external offences were marked and abandoned, while the deeper incongruity between the national religion and the teaching of the Prophets was missed.
If we seek in this period for the rise of ideas which shall bridge over the change from the popular religion on the one hand, and the religion of Jeremiah on the other, to the complete unity of the national religion under Nehemiah and Ezra, we shall find a most important link in the Book of Ezekiel.
The Book of Ezekiel is said to be the least read book in the Bible, yet its author plays a most important part in the history of Israel's religion, and to grasp the position which he occupies is to have a focus point from which the whole development may be conveniently grasped. The Prophet probably got a better hearing from his contemporaries than any of his predecessors. He accompanied the body of captives who left Jerusalem for Babylon in the year 597, and his works date from soon after that year and go down to about 570. The men to whom he was called to speak were therefore his fellow captives, and he had not to look far for a text for his sermons. His hearers were in Babylon for their sins, and they knew it. His style of preaching is difficult, and his method of embodying his message in visions marks a new phenomenon in Israel's religion. He states truth in strange and fanciful figures, a method which was to form an example for the later works of Judaism, and if we detect in Ezekiel a return to the extravagance of the earlier prophecy, we must make allowance for the tragic times in which he lived; especially must we do this where we trace a falling off from his predecessors in moral insight and in the ritualistic influence which his work undoubtedly left behind him.
Ezekiel continues the work of the pre-exilic Prophets in that he proclaims their characteristic doctrines, and naturally he shows distinct traces of the influence of Jeremiah. What is new, is that he gives to those doctrines a more fixed and somewhat pedantic form, and a greater self-consciousness is discernible; the prophecies are accurately arranged, and the language is marked by precision; rhetoric is less frequent, and the prophecies look more fit for reading than for delivery. The idea of God is the same as in the earlier Prophets, but in Ezekiel it is elevated and rarified; especially is great emphasis laid upon the attribute of holiness, which is however a ceremonial rather than a purely ethical conception. The characteristic idea of the Prophets, that Jehovah chose Israel not for their own sakes, becomes the idea that Jehovah did this for His own sake alone, and this is so often repeated that it almost looks like arbitrariness. The cause of Judah's punishment is still traced to the sin of the people, but that sin is now definitely determined to be idolatry; and this is insisted on almost to the exclusion of the social and ethical wrongs assailed by the earlier Prophets. While, however, Ezekiel enforces the bitter lessons of the Exile, he carefully distinguishes the true interpretation of that disaster from that which rose readily to the popular mind. He disposes of the conception that the Captivity was due to the inability of Jehovah to defend His own land (xxxvi. 20); it was a punishment for sin (xxxix. 23), and in His own time He will prove this by restoring them to their land again (xxxix. 25). Neither will he allow them to rest in the flattering thought that they were only suffering for the unvisited sins of a former generation; he insists, probably with greater rigour than experience would sanction, that each man bears his own sin, and never suffers for the sins of others. But to those who admit the justice of his charges, and who therefore regard the future as hopeless, he preaches a tender doctrine of forgiveness and the possibility of cleansing from sin. From the events of his times, he seeks to draw lessons which should redeem the mistakes that had been made in the past: the teaching of the Prophets must be kept before the people in definite rules and religious ceremonies. Old customs, whose original significance had long been forgotten, were invested with new interpretations worthy of the true religion of Jehovah, and were made not only customs, but religious commands. In the book which bears his name, and especially in chapters xl.-xlviii., he outlines a policy in which the whole of national life is comprehended in its religious significance, and thus the calamity of future apostasy prevented. The new State is to centre round the idea of worship: the Temple with its services and appointments is to be the expression of the national life. Now in this scheme there is little doubt that we have the beginning of the Levitical system, for Ezekiel is related to Leviticus as the rough sketch to the finished plan. If Leviticus in its present form existed in Ezekiel's time, then the work of the Prophet was not only entirely unnecessary, but careless and presumptuous. Some of the facts which point to the priority of Ezekiel to the Levitical Code may be noticed. In the Levitical Code we find that a distinction is made between priests and Levites. This is not found in Deuteronomy (xvii. 9, 18; xviii. 1) but is first found in Ezekiel (xliv. 10–15), where it is explained to be due to the degradation of the Levites as a punishment for leading the people into idolatry; in Leviticus we reach the final stage, where the distinction is accepted without explanation. In Ezekiel we have no mention of the high-priest or of the Day of Atonement, both of which figure so largely in the Priest's Code, although we can find foreshadowings of the Day of Atonement (Ezek. xlv. 18–20). Indeed we meet with no mention of the Day of Atonement, apart from the Priestly Code, until Zechariah (vii. 5; viii. 19). The general conclusion may be safely drawn, that during and after the Exile, Ezekiel's ideas were stiffened and developed into the full legislation now preserved for us in Leviticus.
We may rightly claim Ezekiel to be the founder of Judaism, with its transcendent conception of Jehovah and its great attention to ceremonial detail, and we are bound therefore to recognise in Ezekiel a falling off from the ideals of the pre-exilic Prophets; he is a prophet in priest's clothing. Yet it may be questioned whether the idealistic teaching of the Prophets could have been preserved through the periods of the Exile and the Restoration, without this formal process. An outer husk of formality had to develop in order that the living kernel might be protected during the critical years when Persia, Greece, and Rome were to press their alien ideas upon this people. It has been well for the world that Ezekiel clothed the Prophets' teaching in the resisting garments of Judaism.
The Exile could not fail to leave upon the Jewish nation an imperishable mark, and they emerged from that trial a different people. It was a shock that brought a repentance the Prophets had often laboured for in vain, and this repentance was marked by the initiation of many new movements in thought, and by a more stringent and solemn observance of their peculiar institutions. Probably in that alien land many of the Jews adopted the customs of their conquerors, since it is estimated that not more than a small fraction returned to Palestine. This defection would impress upon those who remained faithful the necessity for a strict policy of separation, and from this time certain institutions which had been inherited from ancient Semitic practice received a new meaning. Chief among these may be noticed the observance of the Sabbath, and the rite of circumcision. The observance of a certain day as sacred to the gods is a custom that is found in nearly all early religions, and there are traces of such an observance in the Babylonian religion. We do not find however in the historical books of the Bible that mention of the Sabbath which would be expected, if it was observed with the strictness common after the Exile. There are traces of an observance, not strictly defined, save that it is in association with the new moon feasts, and is combined with social relaxation (2 Kings iv. 22, 23; Hosea ii. 11; Amos viii. 5; Isa. i. 13). Even before the Exile however a more religious conception had arisen (Jer. xvii. 19–27), and is even then referred to as an earlier command. The change after the Exile was towards an ever increasing strictness (Isa. lvi. 2, 4, 6; lviii. 13; lxvi. 23; Neh. xiii. 15–22).
The rite of circumcision was by no means peculiar to the Jewish religion (Jer. ix. 25, 26), except perhaps in so far as it was performed in infancy: its origin and growth are very obscure. Its original significance was early lost and its interpretation was probably due to the Prophets themselves, who often referred to a spiritual circumcision, and thus made possible the full ceremonial interpretation which became so important a feature in later Judaism.
We have seen that there is evidence to prove that the religion of Israel had not always been averse to the use of idols as part of the legitimate worship of Jehovah. The Prophets began the protest against this, not so much because of its principles, but because of the immoral practices with which idol worship was connected. But after the Exile, idolatry was for ever separated from the worship of Jehovah, and in the later Prophets idolatry becomes the target for their most scornful invective. It has been suggested that this new abhorrence accounts for the non-return of the Ark, which in this period disappears from history.
