Exodus 18:14, 22

So when Moses’ father-in-law saw all that he did for the people, he said, “What is this thing that you are doing for the people? Why do you alone sit, and all the people stand before you from morning until evening?”

And let them judge the people at all times. Then it will be that every great matter they shall bring to you, but every small matter they themselves shall judge. So it will be easier for you, for they will bear the burden with you.
