Exodus 18:22-24

Let them judge the people at all times; and let it be that every major dispute they will bring to you, but every minor dispute they themselves will judge. So it will be easier for you, and they will bear the burden with you. If you do this thing and God so commands you, then you will be able to endure, and all these people also will go to their place in peace.” So Moses listened to his father-in-law and did all that he had said.
