Exodus 18:22-25

22Let them judge the people all the time. Then let every major case be brought to you, but every minor case they can judge for themselves. Make it easier for yourself, as they bear the burden with you.

23If you do this thing as God so commands you, then you will be able to endure, and all these people will go to their places in shalom.”

24So Moses listened to his father-in-law and did everything he said.

25Moses chose capable men out of all Israel, and made them heads over the people, rulers of thousands, hundreds, fifties and tens.
