But he also insisted on the regular execution of justice, and his chief strength lay in the orderly administration of his country. Side by side with this went the final removal and absorption of the Canaanites. Both probably served the same object. Solomon required a great deal of money and labour for his costly buildings. His subjects must supply them. He made no distinctions amongst the population, no one escaped the common burdens. To him all Israel formed one unit and was partitioned, without regard to the differences between the tribes or the distinction between Israelite and Canaanite, into twelve zones, each of which was administered by a governor. Some of their names have been lost. The amount to be paid in taxes was regulated on the basis of this division. The compulsory service which Solomon required for his mighty structures for war and peace, were doubtless arranged in a similar manner. In Lebanon alone he is said to have kept ten thousand men who rendered such service, constantly occupied under Adoniram. The distinction between Israelites and Canaanites was continued only to a certain extent, in that what had formerly been the Canaanitish zones were considerably smaller than the others. Thus, when it came to their turn to serve, the Canaanites were more affected; the forcible incorporation in Israel, indeed, made them liable to be called on. [Sidenote: [_ca._ 940-930 B.C.]] Such burdens were unknown to the simple courts of David and Saul, and they must now, therefore, have weighed all the more heavily. Freedom, as the possession of the subject, was little regarded. No wonder, then, that in course of time the discontent, probably long nourished in secret, broke out into fierce rebellion. It was no accident that it started in the house of Joseph, that is, from Ephraim, still less that it proceeded from one of Solomon’s overseers. From two sources, the ancient dislike of the northern tribes to the house of Jesse, and the discontent with the present harsh government, the waters flowed into the same channel.
