Exodus 18:22

At all seasons. — Not on occasional court days, as had been the custom of Moses, but day by day continually.

Every great matter they shall bring unto thee. — It must have been left to the judges themselves to decide what were “great” and what were “small matters.” Under ordinary circumstances, courts would be inclined to extend their jurisdiction, and take enlarged views of their competency; but the difficulties of desert life were such as to counteract this inclination, and induce men to contract, rather than widen, their responsibilities. When the wilderness life was ended, the judicial system of Jethro came to an end also, and a system at once simpler and more elastic was adopted.
