Exodus 18:18-20

18You and these people who come to you will only wear yourselves out. The work is too heavy for you; you cannot handle it alone. 19Listen now to me and I will give you some advice, and may God be with you. You must be the people’s representative before God and bring their disputes to him. 20Teach them his decrees and instructions, and show them the way they are to live and how they are to behave.
