Exodus 18:21-22

21But you should seek out capable men out of all the people—men who fear God, men of truth, who hate bribery. Appoint them to be rulers over thousands, hundreds, fifties and tens.

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.
