Exodus 18:13-16

13The next day Moses sat to judge the people, and the people stood around Moses from morning till evening.

14When Moses' father-in-law saw all that he was doing for the people, he said, "What is this that you are doing for the people? Why do you sit alone, and all the people stand around you from morning till evening?"

15And Moses said to his father-in-law, "Because the people come to me to inquire of God;

16when 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."
