Exodus 18:13-18

Now the next day Moses sat to judge [the disputes] the people [had with one another], and the people stood around Moses from dawn to dusk. When Moses’ father-in-law saw everything that he was doing for the people, he said, “What is this that you are doing for the people? Why are you sitting alone [as a judge] with all the people standing around you from dawn to dusk?” Moses said to his father-in-law, “Because the people come to me to ask [about the will] of God. When they have a dispute they come to me, and I judge between a man and his neighbor and I make known the statutes of God and His laws.” Moses’ father-in-law said to him, “The thing that you are doing is not good. You will certainly wear out both yourself and these people who are with you, because the task is too heavy for you [to bear]; you cannot do it alone.
