Deuteronomy 1:13-16

13Select wise and practical men, those known among your tribes, whom I may appoint as your leaders.”

14You replied to me that what I had said to you was good.

15So I chose as your tribal leaders wise and well-known men, placing them over you as administrators of groups of thousands, hundreds, fifties, and tens, and also as other tribal officials.

16I furthermore admonished your judges at that time that they should pay attention to issues among your fellow citizens and judge fairly, whether between one citizen and another or a citizen and a resident foreigner.
