Exodus 18:13-16

13And it came to pass on the morrow, that Moses sat to judge the people: and the people stood by Moses from the morning unto the evening. 14And when Moses’ father in law saw all that he did to the people, he said, What is this thing that thou doest to the people? why sittest thou thyself alone, and all the people stand by thee from morning unto even? 15And Moses said unto his father in law, Because the people come unto me to enquire of God: 16When they have a matter, they come unto me; and I judge between one and another, and I do make them know the statutes of God, and his laws.1
