Deuteronomy 1:13-16

13Provide you wise and understanding and known men, according to your tribes, that I may make them your chiefs.

14And ye answered me, and said, The thing that thou hast spoken is good [for us] to do.

15So I took the chiefs of your tribes, wise men and known, and made them chiefs over you, captains of thousands, and captains of hundreds, and captains of fifties, and captains of tens, and officers for your tribes.

16And I commanded your judges at that time, saying, Hear [the causes] between your brethren, and judge righteously between a man and his brother, and him also that sojourneth with him.
