The prophets are thoroughly Oriental figures, and the interpretation of their profound religious experiences requires a particular sympathy which is not inherent in Western minds. Their writings are to be understood in the light of their age and of the conditions which gave birth to them. With few exceptions they are preserved in fragmentary form, with additions and adjustments which were necessary in order to make them applicable to later conditions. When, as often, the great figures have been made the spokesmen of the thought of subsequent generations, the historical criticism of the prophecies becomes one of peculiar difficulty.[24] According to the historical traditions it is precisely in the age of Jeroboam II. and Uzziah that the first of the extant prophecies begin (see AMOS and HOSEA). Here it is enough to observe that the highly advanced doctrines of the distinctive character of Yahweh, as ascribed to the 8th century B.C., presuppose a foundation and development. But the evidence does not allow us to trace the earlier progress of the ideas. Yahwism presents itself under a variety of aspects, and the history of Israel's relations to the God Yahweh (whose name is not necessarily of Israelite origin) can hardly be disentangled amid the complicated threads of the earlier history. The view that the seeds of Yahwism were planted in the young Israelite nation in the days of the "exodus" conflicts with the belief that the worship of Yahweh began in the pre-Mosaic age. Nevertheless, it implies that religion passed into a new stage through the influence of Moses, and to this we find a relatively less complete analogy in the specific north Israelite traditions of the age of Jehu. The change from the dynasty of Omri to that of Jehu has been treated by several hands, and the writers, in their recognition of the introduction of a new tendency, have obscured the fact that the cult of Yahweh had flourished even under such a king as Ahab. While the influence of the great prophets Elijah and Elisha is clearly visible, it is instructive to find that the south, too, has its share in the inauguration of the new era. At Horeb, the mount of God, was located the dramatic theophany which heralded to Elijah the advent of the sword, and Jehu's supporter in his sanguinary measures belongs to the Rechabites, a sect which felt itself to be the true worshipping community of Yahweh and is closely associated with the Kenites, the kin of Moses. It was at the holy well of Kadesh, in the sacred mounts of Sinai and Horeb, and in the field of Edom that the Yahweh of Moses was found, and scattered traces survive of a definite belief in the entrance into Palestine of a movement uncompromisingly devoted to the purer worship of Yahweh. The course of the dynasty of Jehu--the reforms, the disastrous Aramaean wars, and, at length, Yahweh's "arrow of victory"--constituted an epoch in the Israelite history, and it is regarded as such.[25]
