Deuteronomy 1:13-15

1:13 Select wise and practical men, those known among your tribes, whom I may appoint as your leaders.” 1:14 You replied to me that what I had said to you was good. 1:15 So 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.
