Deuteronomy 1:16-18

Then I told your leaders, “Listen to the arguments between your people. Judge fairly between two Israelites or between an Israelite and a foreigner. When you judge, be fair to everyone; don’t act as if one person is more important than another, and don’t be afraid of anyone, because your decision comes from God. Bring the hard cases to me, and I will judge them.” At that time I told you everything you must do.
