What does Deuteronomy 1:18 mean?

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

I commanded your judges at that time, saying, “Hear cases between your brothers, and judge righteously between a man and his brother, and the foreigner who is living with him.

You shall not show partiality in judgment; you shall hear the small and the great alike. You shall not be afraid of the face of man, for the judgment is God’s. The case that is too hard for you, you shall bring to me, and I will hear it.”

We traveled from Horeb, and went through all that great and terrible wilderness which you saw, by the way to the hill country of the Amorites, as Yahweh our God commanded us; and we came to Kadesh Barnea.

I said to you, “You have come to the hill country of the Amorites, which Yahweh our God gives to us.

Behold, Yahweh your God has set the land before you. Go up, take possession, as Yahweh, the God of your fathers, has spoken to you. Don’t be afraid, neither be dismayed.”
