Deuteronomy 1:13-15

131Obtain for yourselves men who are wise, discerning, and informed from your tribes, and I will appoint them as your heads.’ 14And you answered me and said, ‘The thing which you have said to do is good.’ 15So I took the heads of your tribes, wise and informed men, and 2appointed them as heads over you, commanders of thousands, 3hundreds, 4fifties, and 5tens, and officers for your tribes.
