What advice did Jethro give Moses about judging all the people's problems by himself?
Jethro advised Moses that one man could not handle all the people's problems alone. He told Moses he must set up a system for dealing with their problems, rather than judging every matter himself, because the current practice would wear him away and was too much for him.
Les explains that Jethro, Moses' father-in-law and a Midianite, came on the scene and saw the multitude of Israelites besieging Moses with one problem after another. Jethro told Moses there was no way one man could do all of this alone and that he had to set up a system of dealing with their problems. Jethro asked Moses why he sat alone while all the people stood by him from morning, and Moses answered that the people came to him to inquire of God, that he judged between one another, and that he made them know the statutes of God and His laws. Jethro then said the thing Moses did was not good, that Moses would surely wear away, and that it was too much. Les notes that Jethro was a Midianite priest and a relative of Abraham, though he does not believe Jethro was a believer in the God of Abraham.
And 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?
