This catalogue comprehended all the men above twenty years of age, to which may be added 23,000 of the tribe of Levi, "all males from a month old and upward: for they were not numbered among the children of Israel, because there was no inheritance given them among the children of Israel." The whole amounted to six hundred and six thousand seven hundred.[17] In every tribe there was a chief called the Prince of the Tribe, or the Head of Thousands; and under him were the Princes of Families, or Commanders of Hundreds. For example, we find that at the muster which was made of the Hebrews in the Wilderness of Sinai, Nahshon, the son of Amminadab, was Prince of the Tribe of Judah. This tribe, again, like all the others, was divided into several families; the term being used here not in its ordinary acceptation, to signify a mere household, but rather in the heraldic sense, to denote a lineage or kindred descended from a common ancestor, and constituting the main branches of an original stock. In this respect the Israelites were guided by the same principle which regulates precedency among the Arabs, as well as among our own countrymen in the Highlands of Scotland. It appears, moreover, that a record of these families, of the households in each, and even of the individuals belonging to every household, was placed in the hands of the chief ruler; for it is related that, on the suspicion excited with regard to the spoils of Jericho and the discomfiture at Ai, "Joshua brought Israel by their tribes, and the tribe of Judah was taken; and he brought the family of Judah, and he took the family of the Zarhites; and he brought the family of the Zarhites man by man, and Zabdi was taken; and he brought his household man by man, and Achan, the son of Carmi, the son of Zabdi, the son of Zerah, of the tribe of Judah, was taken."[18] We may collect from the twenty-sixth chapter of the book of Numbers, that the Heads of Families, at the time the children of Israel encamped on the eastern bank of the Jordan, were in number fifty-seven. If to these we add the thirteen Princes, the Heads of tribes, the sum of the two numbers will be seventy; whence there is some ground for the conjectures of those who allege, that the council which Moses formed in the Wilderness consisted of the patriarchal chiefs, who in right of birth were recognized as bearing an hereditary rule over the several sections of the people.
