[66] THE next day, as Raguel saw Moses in the of a crowd of business for he determined the differences of those that referred them to him, every one still going to him, and supposing that they should then only obtain justice, if he were the arbitrator; and those that lost their causes thought it no harm, while they thought they lost them justly, and not by partiality. Raguel however said nothing to him at that time, as not desirous to be any hinderance to such as had a mind to make use of the virtue of their conductor. But afterward he took him to himself, and when he had him alone, he instructed him in what he ought to do; and advised him to leave the trouble of lesser causes to others, but himself to take care of the greater, and of the people's safety, for that certain others of the Hebrews might be found that were fit to determine causes, but that nobody but a Moses could take of the safety of so many ten thousands. "Be therefore," says he, "insensible of thine own virtue, and what thou hast done by ministering under God to the people's preservation. Permit, therefore, the determination of common causes to be done by others, but do thou reserve thyself to the attendance on God only, and look out for methods of preserving the multitude from their present distress. Make use of the method I suggest to you, as to human affairs; and take a review of the army, and appoint chosen rulers over tens of thousands, and then over thousands; then divide them into five hundreds, and again into hundreds, and into fifties; and set rulers over each of them, who may distinguish them into thirties, and keep them in order; and at last number them by twenties and by tens: and let there be one commander over each number, to be denominated from the number of those over whom they are rulers, but such as the whole multitude have tried, and do approve of, as being good and righteous men; ¹ and let those rulers decide the controversies they have one with another. But if any great cause arise, let them bring the cognizance of it before the rulers of a higher dignity; but if any great difficulty arise that is too hard for even their determination, let them send it to thee. By these means two advantages will be gained; the Hebrews will have justice done them, and thou wilt be able to attend constantly on God, and procure him to be more favorable to the people."
