Deuteronomy 1:12

I spoke to you at that time, saying, “I am not able to bear you myself alone.

The LORD your God has multiplied you, and behold, you are today as the stars of the sky for multitude.

May the LORD, the God of your fathers, make you a thousand times as many as you are and bless you, as he has promised you!

Take wise men of understanding who are respected among your tribes, and I will make them heads over you.”

You answered me, and said, “The thing which you have spoken is good to do.”

So I took the heads of your tribes, wise and respected men, and made them heads over you, captains of thousands, captains of hundreds, captains of fifties, captains of tens, and officers, according to your tribes.
