Deuteronomy 1:15-18

15So I took the leading men of your tribes, wise and respected men, and appointed them to have authority over you—as commanders of thousands, of hundreds, of fifties and of tens and as tribal officials. 16And I charged your judges at that time, “Hear the disputes between your people and judge fairly, whether the case is between two Israelites or between an Israelite and a foreigner residing among you. 17Do not show partiality in judging; hear both small and great alike. Do not be afraid of anyone, for judgment belongs to God. Bring me any case too hard for you, and I will hear it.” 18And at that time I told you everything you were to do.
