Deuteronomy 1:10

Turn, and take your journey, and go to the hill country of the Amorites and to all the places near there: in the Arabah, in the hill country, in the lowland, in the South, by the seashore, in the land of the Canaanites, and in Lebanon as far as the great river, the river Euphrates.

Behold, I have set the land before you. Go in and possess the land which the LORD swore to your fathers—to Abraham, to Isaac, and to Jacob—to give to them and to their offspring after them.’”

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

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!

How can I myself alone bear your problems, your burdens, and your strife?

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