The functions of the Levites throughout the country seem to have differed somewhat in successive periods of their history. Here, as in other matters, there was doubtless some development, according as new wants appeared in the spiritual condition of the people, and consequently new obligations for the Levites to fulfil. When the people fell under special temptations to idolatry, it would naturally fall to the Levites, in connection with the priesthood, to warn them against these temptations, and strive to keep them faithful to their God. But it does not appear that even the Levites could be trusted to continue faithful. It is a sad and singular fact that a grandson of Moses was one of the first to go astray. The Authorized Version, indeed, says that the young man who became a priest to the Danites when they set up a graven image in the city of Dan, was Jonathan, the son of Gershom, the son of Manasseh (Judg. xviii. 30). But the Revised Version, not without authority, calls him Jonathan, the son of Gershom, the son of Moses. Here we have a glimpse of two remarkable facts: in the first place, that a grandson of Moses, a Levite, was located in so confined a place that he had to leave it in search of another, "to sojourn where he could find a place"--so entirely had Moses abstained from steps to secure superior provision for his own family; and, in the second place, that even with his remarkable advantages and relations, this Jonathan, in defiance of the law, was tempted to assume an office of priesthood, and to discharge that office at the shrine of a graven image. We are far indeed from the truth when we suppose that the whole nation of Israel submitted to the law of Moses from the beginning with absolute loyalty, or when we accept the prevalent practice among them at any one period as undoubted evidence of what was then the law. But let us now turn our attention to the distribution of the Levites as it was planned. We say deliberately "as it was planned," because there is every reason to believe that the plan was not effectually carried out. In no case does there seem to have been such a failure of official arrangements as in the case of Levi. And the reason is not difficult to find. Few of the cities allotted to them were free of Canaanites at the time. To get actual possession of the cities they must have dispossessed the remaining Canaanites. But, scattered as they were, this was peculiarly difficult. And the other tribes seem to have been in no humour to help them. Hence it is that in the early period of the Judges we find Levites wandering here and there seeking for a settlement, and glad of any occupation they could find (Judg. xviii. 7, xix. 1).
