Deuteronomy 1:11

8 See, all the land is before you: go in and take for yourselves the land which the Lord gave by an oath to your fathers, Abraham, Isaac, and Jacob, and to their seed after them.

9 At that time I said to you, I am not able to undertake the care of you by myself;

10 The Lord your God has given you increase, and now you are like the stars of heaven in number.

11 May the Lord, the God of your fathers, make you a thousand times greater in number than you are, and give you his blessing as he has said!

12 How is it possible for me by myself to be responsible for you, and undertake the weight of all your troubles and your arguments?

13 Take for yourselves men who are wise, far-seeing, and respected among you, from your tribes, and I will make them rulers over you.

14 And you made answer and said to me, It is good for us to do as you say.
