Exodus 18:17

13And it came to pass on the morrow, that Moses sat to judge the people: and the people stood by Moses from the morning unto the evening.

14And when Moses’ father in law saw all that he did to the people, he said, What is this thing that thou doest to the people? why sittest thou thyself alone, and all the people stand by thee from morning unto even?

15And Moses said unto his father in law, Because the people come unto me to enquire of God:

16When they have a matter, they come unto me; and I judge between one and another, and I do make them know the statutes of God, and his laws.

17And Moses’ father in law said unto him, The thing that thou doest is not good.

18Thou wilt surely wear away, both thou, and this people that is with thee: for this thing is too heavy for thee; thou art not able to perform it thyself alone.

19Hearken now unto my voice, I will give thee counsel, and God shall be with thee: Be thou for the people to God-ward, that thou mayest bring the causes unto God:

20And thou shalt teach them ordinances and laws, and shalt shew them the way wherein they must walk, and the work that they must do.

21Moreover thou shalt provide out of all the people able men, such as fear God, men of truth, hating covetousness; and place such over them, to be rulers of thousands, and rulers of hundreds, rulers of fifties, and rulers of tens:
