It is hardly surprising to find that this Prophetical literature was in turn liable to redaction, though in a different degree and for a different reason, since it has been preserved to us under peculiar conditions. This at first may seem terribly confusing to the bewildered student, and it is here that tired men reject criticism and all its works. To such the reminder cannot be spared that in any branch of Science the same conditions have to be overcome, and if he would understand the Old Testament and reap the magnificent reward that its earnest study gives, he must be prepared to face the facts and labour at their solution.

First of all then, it must be noted that the Books of the Prophets are not so much literature, in the ordinary sense of the word, as reported rhetoric, with the qualification that the reporter and the speaker may be usually assumed to be the same. In most cases the speeches were written out by the Prophet himself soon after they were delivered, although sometimes this was done by others long after, and expanded or altered, as is actually reported to have been the case with the prophecies of Jeremiah (Jer. xxxvi.).

In the second place, the literature reveals the fact that there does not seem to have been in that age any conception of literary property; ideas are borrowed directly from one Prophet by another, and sometimes direct quotation is made without any acknowledgment or indication of the source. The Prophet's scribe, his school or followers, could amend or paraphrase; later generations could evidently insert a qualifying phrase, temper a threat with a qualifying condition, or to the doom of exile add a promise of restoration. When it is noticed that messages like those of Amos or Hosea end unexpectedly in hopeful words, and when it is recollected that these Prophets have been used as Service Books in the Synagogue and may have been therefore altered to suit the purpose, then we shall understand the problem that faces us and why a shadow of suspicion should rest on promises of restoration that are to be found in pre-exilic writings. Let it be remembered however that it is no true critical canon to assume that prediction cannot be made; but what are we to do when such a prediction fits ill with the context, breaks the sense, is foreign to the outlook of the speaker, and is in later style?

Finally, there seem to have been many prophecies circulated anonymously, and since a place had to be found for these they were inserted in other writers, on no principle that we can discover, or more often were grouped together at the end of some notable Prophet's works. In Zechariah we have to suppose three strata of different authorship and date, or give up the rational study of the Book altogether; and in the famous case of the Book of Isaiah we have to suppose that some of the early chapters are the work of a post-exilic author, while chapters xl.-lxvi. are a heterogeneous collection by a number of writers, of which chapters xl.-lv. are recognised to be by one hand, and that, one of the most wonderful personalities which has contributed to the Old Testament; about that grand figure we only know one thing, that he was not Isaiah of Jerusalem. This has been called "sawing Isaiah asunder" and making the Bible a piece of patchwork and the critics are blamed; but if they are right, these complaints are not directed at them, but at the Bible itself, a proceeding which to say the least, is not pious. When a writer could say many years later that revelation came of old time in many fragments (Heb. i. 1), others beside critics fall under these hasty condemnations.

It is refreshing to turn from this less interesting part of our subject, which nevertheless demands serious study from anyone who would be informed where ignorance has done and still is doing so much harm, and to examine the features which distinguish the work of the literary Prophets. We have already spoken of the novelty of their message. Whatever theory is chosen for the study of Old Testament history, nothing quite prepares us for the message of the Prophet Amos. What an inspiration we miss because he does not stand in our Bibles in his rightful place, at the head of the Prophets! His bravery and ruggedness remind us of Elijah, but he brings something that Elijah is far from giving us. Elijah was very jealous for the due recognition of Jehovah as the only God for Israel; Amos is jealous for the recognition of the true character of Jehovah. That is to say, we receive from Amos definite teaching concerning the character of Jehovah and His relations to the people of Israel, and these doctrines are startling to Israelitish ears.

Almost the first thing that strikes us as an outstanding characteristic of the Prophets is that they are conscious of a call to which they often appeal. Five of them definitely refer to the circumstances of their call (Amos vii. 14; Hosea i. 2; Isaiah vi.; Jer. i. 4–10; Ezek. i. 1–ii. 3). The same is true of their predecessors, but in a different way; they stand as defenders of the national religion because they belong to the prophetic guilds or possess certain gifts of vision. On the other hand the literary Prophets are against the national religion as a perversion of the true, and to this weary and warlike work they are called by immediate and special summons of God. This call is not self-originated nor can it be evaded (Jer. xx. 9), and in some cases there has been no preparation for the office (Amos vii. 14, 15), and even positive unfitness (Jer. i. 6). They are very careful therefore to distinguish themselves from the schools of prophets. Professionalism has disappeared, and in Jeremiah the official idea also vanishes.

The peculiar mental condition of the Prophets has of late years attracted a great deal of attention. The rapture and holy frenzy into which they are sometimes thrown remind us of the phenomena accompanying the early Prophetism, studied in our last lecture; but this is now accidental and is becoming rare. The Prophets often speak of this as "the hand of the Lord" upon them (Isa. viii. 11); in the visions of Ezekiel the effect is often described as overpowering (Ezek. iii. 14 ff.). There is a similarity between the accompaniments of these states and the trances which have been found in so many religious movements, and which are now attracting the attention of the scientific world so seriously. Only the results differ remarkably from the effects obtained in hypnotic and sub-conscious states, with which the prophetic gift has sometimes been compared. The Prophet still exhibits his natural style when under the influence of the Word of the Lord. Yet it may be that there is something to be learned along the lines of modern research; we know that if certain states of mental passivity can be induced, there lies open a new realm of knowledge, which, although it can be accounted for, cannot be summoned under ordinary mental conditions; add to this the superior moral constitution which seems to be missing from the mediums of spiritualistic phenomena to-day, and the prophetic consciousness becomes more comprehensible. The Prophets often speak of visions, but it is difficult to gather their actual character. It can hardly be objective; it is more like the artistic vision which creates within the mind in perfect detail and objectivity, so that what is seen has greater reality than any reproduction on canvas or in stone. The mind would seem to project its vision by the strength of its imaginative powers, so that, owing to the emotion aroused by the nature of the truth perceived, the revelation appears to come from an entirely external source. Sometimes it would seem to be an actual beholding of some natural object, which induces a train of thought, as the case of Amos's vision of the plumb-line may well be. We cannot think either of any organic hearing of their message, since they sometimes also declare that they "see" it.

Their predictive power has been exaggerated, chiefly because it was thought that this was the only office of the Prophet. Where it occurs it is mostly a natural deduction from their insight into the movements of their age, their conception of the unchangeable character of Jehovah, and their belief in His providential government; the emphasis is never upon details, and it may be added that the prediction is by no means always fulfilled. Their vision of the future usually takes a certain outline, or order; a national calamity is immediately impending, in which they recognise the punishment of the people's sins and the complete triumph and vindication of Jehovah; this will result in a purifying of the nation, and in the immediate succession there will come the Messianic or ideal era. Still there are predictions which cannot be explained on any theory yet broached, such as the prediction by Isaiah of the destruction of Sennacherib's army, or Jeremiah's prophecy of the Restoration. If this is ordinary second sight, then it is strange that it should have occurred in so many cases at this time when prophecy was dropping its mysterious accompaniments. Yet it may be recalled that in the history of all nations there has been, in times of great national affliction, a tendency to prophecy of this order, which can sometimes claim a remarkable fulfilment. The distinguishing glory of Israel's prophecy is, however, to be sought in its ethical character, and it is perhaps to the writings of men like our own Carlyle, where we often catch the old prophetic ring, that we are to look for its analogy.

Among the things that separate Amos from his predecessors is the use of a literary channel for the dissemination of his teaching, which was of course primarily preaching. This in itself marks a great change. What was it that led the Prophet to write down the message which he had delivered? It may have been that there was a tendency towards literature at that particular period, but even before this the habit of keeping records must have commenced, while there is evidence of collections of poems or sagas, such as the Book of Jasher, or the Book of the Wars of the Lord, being in existence from a very early period. It is evident therefore that we need some particular occurrence to account for the adoption of literature as the vehicle of Prophecy. It has been suggested that the cause is to be sought initially in the rejection of the message of Amos by those to whom it was delivered: he was aware of the permanent application of the truths that he had delivered, and since his own times would not hearken he resolved to commit them to the verdict of posterity. The example once set, it was natural for the succeeding Prophets to wish to give something more than the fleeting character of the spoken word to teaching that was new and that had been rejected, and therefore to adopt this form (Isa. viii. 16 f.). Whatever the cause, we are thankful for the results.

The channel chosen for the preservation of their messages was not purely literary; the form is not that of the essay, or thesis; it has not the studied elegance of poetry, yet it rises above prose, and rhythmic verse is found scattered throughout their writings. These reports of passionate oratory fall naturally into poetic form as the Prophet is carried away by his message. Especially do we find a very extensive use of symbolism, which has proved a trap into which the literalist has hastened to fall.
