Deuteronomy 1:11

7 Resume your journey and go to the hill country of the Amorites; go to all the neighboring peoples in the Arabah, in the hill country, in the foothills, in the Negev, and along the seacoast to the land of the Canaanites and to Lebanon, as far as the great River Euphrates.

8 See, I have placed the land before you. Enter and possess the land that the LORD swore He would give to your fathers Abraham, Isaac, and Jacob, and to their descendants after them.”

9 At that time I said to you, “I cannot carry the burden for you alone.

10 The LORD your God has multiplied you, so that today you are as numerous as the stars in the sky.

11 May the LORD, the God of your fathers, increase you a thousand times over and bless you as He has promised.

12 But how can I bear your troubles, burdens, and disputes all by myself?

13 Choose for yourselves wise, understanding, and respected men from each of your tribes, and I will appoint them as your leaders.”

14 And you answered me and said, “What you propose to do is good.”

15 So I took the leaders of your tribes, wise and respected men, and appointed them as leaders over you—as commanders of thousands, of hundreds, of fifties, and of tens, and as officers for your tribes.
