13 Choose men, wise and understanding, and known to your tribes, and let me appoint them as your heads.’

14 “And you answered me and said, ‘The word which you have spoken to us to do is good.’

15 “And I took the heads of your tribes, wise men and known, and made them heads over you, leaders of thousands, and leaders of hundreds, and leaders of fifties, and leaders of tens, and officers for your tribes.
