Exodus 18:13-16

13And so it was, on the next day, that Moses sat to judge the people; and the people stood before Moses from morning until evening.

14So when Moses’ father-in-law saw all that he did for the people, he said, “What is this thing that you are doing for the people? Why do you alone sit, and all the people stand before you from morning until evening?”

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

16When they have a difficulty, they come to me, and I judge between one and another; and I make known the statutes of God and His laws.”
