Exodus 18:22-25

22Let them judge the people at all times; and let it be 1that every major 2dispute they will bring to you, but every minor 3dispute they themselves will judge. So it will be easier for you, and 4they will bear the burden with you. 23If you do this thing and God so commands you, then you will be able to 5endure, and all 6these people also will go to 7their place in peace.”
