To all these inquiries, outlines of the answers ought by this time to have become visible. We have seen that the contents of the Book of Amos consist almost entirely of two kinds: facts, actual or imminent, in the history of his people; and certain moral principles of the most elementary order. Amos appeals to no dogma nor form of law, nor to any religious or national institution. Still more remarkably, he does not rely upon miracle nor any so-called "supernatural sign." To employ the terms of Mazzini's famous formula, Amos draws his materials solely from "conscience and history." Within himself he hears certain moral principles speak in the voice of God, and certain events of his day he recognises as the judicial acts of God. The principles condemn the living generation of Israel as morally corrupt; the events threaten the people with political extinction. From this agreement between inward conviction and outward event Amos draws his full confidence as a prophet, and enforces on the people his message of doom as God's own word.

The passage in which Amos most explicitly illustrates this harmony between event and conviction is one whose metaphors we have already quoted in proof of the desert's influence upon the prophet's life. When Amos asks, Can two walk together except they have made an appointment? his figure is drawn, as we have seen, from the wilderness in which two men will hardly meet except they have arranged to do so; but the truth, he would illustrate by the figure, is that two sets of phenomena which coincide must have sprung from a common purpose. Their conjunction forbids mere chance. What kind of phenomena he means, he lets us see in his next instance: Doth a lion roar in the jungle and have no prey? Doth a young lion let forth his voice from his den except he be catching something? That is, those ominous sounds never happen without some fell and terrible deed happening along with them. Amos thus plainly hints that the two phenomena on whose coincidence he insists are an utterance on one side, and on the other side a deed fraught with destruction. The reading of the next metaphor about the bird and the snare is uncertain; at most what it means is that you never see signs of distress or a vain struggle to escape without there being, though out of sight, some real cause for them.[155] But from so general a principle he returns in his fourth metaphor to the special coincidence between utterance and deed. Is the alarum-trumpet blown in a city and do the people not tremble? Of course they do; they know such sound is never made without the approach of calamity. But who is the author of every calamity? God Himself: Shall there be evil in a city and Jehovah not have done it? Very well then; we have seen that common life has many instances in which, when an ominous sound is heard, it is because it is closely linked with a fatal deed. These happen together, not by mere chance, but because the one is the expression, the warning or the explanation of the other. And we also know that fatal deeds which happen to any community in Israel are from Jehovah. He is behind them. But they, too, are accompanied by a warning voice from the same source as themselves. This is the voice which the prophet hears in his heart—the moral conviction which he feels as the Word of God. The Lord Jehovah doeth nothing but He hath revealed His counsel to His servants the prophets. Mark the grammar: the revelation comes first to the prophet's heart; then he sees and recognises the event, and is confident to give his message about it. So Amos, repeating his metaphor, sums up his argument. The Lion hath roared, who shall not fear?—certain that there is more than sound to happen. The Lord Jehovah hath spoken, who can but prophesy?—certain that what Jehovah has spoken to him inwardly is likewise no mere sound, but that deeds of judgment are about to happen, as the ominous voice requires they should.[156]

The prophet then is made sure of his message by the agreement between the inward convictions of his soul and the outward events of the day. When these walk together, it proves that they have come of a common purpose. He who causes the events—it is Jehovah Himself, for shall there be evil in a city and Jehovah not have done it?—must be author also of the inner voice or conviction which agrees with them. Who then can but prophesy? Observe again that no support is here derived from miracle; nor is any claim made for the prophet on the ground of his ability to foretell the event. It is the agreement of the idea with the fact, their evident common origin in the purpose of Jehovah, which makes a man sure that he has in him the Word of God. Both are necessary, and together are enough. Are we then to leave the origin of the Word in this coincidence of fact and thought—as it were an electric flash produced by the contact of conviction with event? Hardly: there are questions behind this coincidence. For instance, as to how the two react on each other—the event provoking the conviction, the conviction interpreting the event? The argument of Amos seems to imply that the ethical principles are experienced by the prophet prior to the events which justify them Is this so, or was the shock of the events required to awaken the principles? And if the principles were prior, whence did Amos derive them? These are some questions that will lead us to the very origins of revelation.

The greatest of the events with which Amos and his contemporaries dealt was the Assyrian invasion. In a previous chapter we have tried to estimate the intellectual effects of Assyria on prophecy.[157] Assyria widened the horizon of Israel, put the world to Hebrew eyes into a new perspective, vastly increased the possibilities of history and set to religion a novel order of problems. We can trace the effects upon Israel's conceptions of God, of man and even of nature.[158] Now it might be plausibly argued that the new prophecy in Israel was first stirred and quickened by all this mental shock and strain, and that even the loftier ethics of the prophets were thus due to the advance of Assyria. For, as the most vigilant watchmen of their day, the prophets observed the rise of that empire, and felt its fatality for Israel. Turning then to inquire the Divine reasons for such a destruction, they found these in Israel's sinfulness, to the full extent of which their hearts were at last awakened. According to such a theory the prophets were politicians first and moralists afterwards: alarmists to begin with, and preachers of repentance only second. Or—to recur to the language employed above—the prophets' experience of the historical event preceded their conviction of the moral principle which agreed with it.

In support of such a theory it is pointed out that after all the most original element in the prophecy of the eighth century was the announcement of Israel's fall and exile. The Righteousness of Jehovah had often previously been enforced in Israel, but never had any voice drawn from it this awful conclusion that the nation must perish. The first in Israel to dare this was Amos, and surely what enabled him to do so was the imminence of Assyria upon his people. Again, such a theory might plausibly point to the opening verse of the Book of Amos, with its unprefaced, unexplained pronouncement of doom upon Israel:—

The Lord roareth from Zion,
And giveth voice from Jerusalem;
And the pastures of the shepherds mourn,
And the summit of Carmel is withered!

Here, it might be averred, is the earliest prophet's earliest utterance. Is it not audibly the voice of a man in a panic—such a panic as, ever on the eve of historic convulsions, seizes the more sensitive minds of a doomed people? The distant Assyrian thunder has reached Amos, on his pastures, unprepared—unable to articulate its exact meaning, and with only faith enough to hear in it the voice of his God. He needs reflection to unfold its contents; and the process of this reflection we find through the rest of his book. There he details for us, with increasing clearness, both the ethical reasons and the political results of that Assyrian terror, by which he was at first so wildly shocked into prophecy.

But the panic-born are always the still-born; and it is simply impossible that prophecy, in all her ethical and religious vigour, can have been the daughter of so fatal a birth. If we look again at the evidence which is quoted from Amos in favour of such a theory, we shall see how fully it is contradicted by other features of his book.

To begin with, we are not certain that the terror of the opening verse of Amos is the Assyrian terror. Even if it were, the opening of a book does not necessarily represent the writer's earliest feelings. The rest of the chapters contain visions and oracles which obviously date from a time when Amos was not yet startled by Assyria, but believed that the punishment which Israel required might be accomplished through a series of physical calamities—locusts, drought and pestilence.[159] Nay, it was not even these earlier judgments, preceding the Assyrian, which stirred the word of God in the prophet. He introduces them with a now and a therefore. That is to say, he treats them only as the consequence of certain facts, the conclusion of certain premises. These facts and premises are moral—they are exclusively moral. They are the sins of Israel's life, regarded without illusion and without pity. They are certain simple convictions, which fill the prophet's heart, about the impossibility of the survival of any state which is so perverse and so corrupt.

This origin of prophecy in moral facts and moral intuitions, which are in their beginning independent of political events, may be illustrated by several other points. For instance, the sins which Amos marked in Israel were such as required no "red dawn of judgment" to expose their flagrance and fatality. The abuse of justice, the cruelty of the rich, the shameless immorality of the priests, are not sins which we feel only in the cool of the day, when God Himself draws near to judgment. They are such things as make men shiver in the sunshine. And so the Book of Amos, and not less that of Hosea, tremble with the feeling that Israel's social corruption is great enough of itself, without the aid of natural convulsions, to shake the very basis of national life. Shall not the land tremble for this, Amos says after reciting some sins, and every one that dwelleth therein?[160] Not drought nor pestilence nor invasion is needed for Israel's doom, but the elemental force of ruin which lies in the people's own wickedness. This is enough to create gloom long before the political skies be overcast—or, as Amos himself puts it, this is enough
