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

16 When 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.

18 Thou 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.

19 Hearken 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:
