Moses now surrounded himself with councillors, who were the chiefs of seventy families. This system became a model for later forms of administration. The Council of Elders participated in important deliberations, and assisted in the management of public business. On the advice of Jethro, his father-in-law, Moses appointed inferior and higher judges, who respectively had under their jurisdiction ten, a hundred, and a thousand families. The people had the right of electing their own judges, whose appointment they then recommended to Moses. These judges were charged to maintain strict impartiality in cases of litigation between members of the tribes of Israel, or between Israelites and strangers. Nor was it within the discretion of the judges to make distinctions between persons of high and low degree. They were also commanded to keep their hands clean from bribes, and to give their verdicts according to the principles of equity, "for justice belongs unto God," and has its source in God himself. Brotherly love, community of interests, equality before the law, equity and mercy were the high ideals which he held before the generations which he had trained. The inculcation of these laws and teachings marked an eventful era in the nation's history. As such it was characterised by the prophets, who called it "the bridal time of the daughter of Israel," and the season of "her espousals, when she went after her God in the land which was not sown." Israel's wanderings had nearly come to a conclusion and the younger generation was well fitted for the attainment of the object of its settlement. A further sojourn in the desert would have inured the people to habits of restlessness, and might have reduced them for ever to the nomadic condition of the Midianites and the Amalekites. They appear to have made an unsuccessful raid in a northern direction, along the old caravan roads. In a second defeat some of them were captured by their enemies. But this discomfiture was apparently avenged by combatants belonging to the tribe of Judah, who were aided by men of the tribe of Simeon, and by Kenites, with whose assistance they seized several cities.
