To all this Israel was exposed, and to more. There are doubts as to the extent of their conquests when they settled down; but there are none that when they did so they still had heathen Canaanites among them. Throughout almost the whole country the population was mixed, and constant intercourse with the conquered peoples was unavoidable. At first these were either Israel's teachers in many of the arts of settled life, or they must have carried on the work of agriculture for their Israelite lords. Moreover many of the sacred places of the land, the sanctuaries which from time immemorial had been resorted to for worship, were either taken over by the Israelites or were left in Canaanite hands. In either case they opened a way for malign influences upon the purer faith. Gradually, too, the tribal feeling asserted itself. The tribal heads regained the position they had held before the domination of Moses and his successor, just as the tribal heads of the Arabs asserted themselves after the death of Mohammed and his immediate successors, and plunged into fratricidal war with the companions of their prophet. The only difference was that, while the circumstances of the Arabs compelled them to retain a supreme head, the circumstances of the Israelites permitted them to fall back into the tribal isolation from which they had emerged. The national life was broken up, the religious life followed in the same path, until, as the Book of Judges graphically says in narrating how Micah set up an Ephod and Teraphim for himself and made his son a priest, "every man did that which was right in his own eyes." With a people so recently won for a higher faith, there could not but follow a recrudescence of heathen or semi-heathen beliefs and practices. To sum up, given a great truth revealed to one man, which, though accepted by a nation, is only half understood by the bulk of them, and given also a great national deliverance and expansion brought about by the same leader, you have there the elements of a great enthusiasm with the seeds of its own decay within it. Such a nation, especially if plied with external temptation, will fall back, not into its first state certainly, but into a condition much below its highest level, so soon as the leader and those who had really comprehended the new truth are removed to a distance or are dead.
