Deuteronomy 1:13-15

13 Set forth for you men wise and discerning, and known to your tribes, that I may appoint them to be heads over you.

14 And ye answered me, and said, Good, is the word which thou hast spoken to be done.

15 So I took heads for your tribes wise men and known, and placed them as heads over you, captains of thousands, and captains of hundreds, and captains of fifties and captains of tens, and overseers for your tribes.
