Deuteronomy 1:15

So I took the chief of your tribes, wise men, and known,.... The principal persons among them, that were remarkable and well known for their wisdom and understanding, whom the people presented to him:

and made them heads over you; rulers of them, as follows:

captains over thousands, and captains over hundreds, and captains over fifties, and captains over tens; see Exodus 18:21

and officers among your tribes; which Jarchi interprets of such that bind malefactors and scourge them, according to the decree of the judges, even the executioners of justice; and so the Jews commonly understand them to be, though some have thought they were judges also.
