Moses listens to his father-in-law and does what he says. He appoints capable men over the people, and they judge ordinary cases while difficult cases come to Moses. Jethro then returns to his own land.

Where this fits in the story: Israel’s growing community now needs a sustainable structure for teaching and adjudication. The episode also prepares for Sinai, where the covenant laws Moses must teach and apply will soon be given in much fuller form.

Evidence boundary: Exodus explicitly says the people stood before Moses from morning to evening and that Jethro warned of exhaustion. It does not describe literal lines, say Jethro watched “from a distance,” narrate Moses’ private sense of responsibility, or present every later leadership hierarchy as a direct command copied from this arrangement.
