Exodus 18:13, 16, 19, 26

The next day Moses sat to judge the people, and the people stood around Moses from morning till evening.

when they have a dispute, they come to me and I decide between one person and another, and I make them know the statutes of God and his laws.”

Now obey my voice; I will give you advice, and God be with you! You shall represent the people before God and bring their cases to God

And they judged the people at all times. Any hard case they brought to Moses, but any small matter they decided themselves.
