The Targum Pseudo-Jonathan closes Jethro's advice with a striking promise: "If thou wilt do this, and exempt thyself from judging (every case) as the Lord shall give thee instruction, thou wilt be able to continue to hear them; and Aaron also and his sons, and all the elders of this people, will resort to the place of Judgment in peace" (Exodus 18:23).
Two details illuminate the advice. First, Jethro explicitly conditions the reform on divine approval: "as the Lord shall give thee instruction." He knows his counsel is valuable only if God confirms it. He is not proposing to override the prophet's covenantal authority; he is proposing a structural change that God will need to endorse. Moses will in fact take the plan to God before implementing it.
Second, and more striking, is the promised outcome: the judges will "resort to the place of Judgment in peace." The Aramaic bishlam — in peace — implies both physical safety and psychological calm. Under Moses's old system, the courtroom was exhausted, tense, endless. Under the new system, Aaron, his sons, and the elders will arrive rested, prepared, and mentally present.
The Torah sometimes defines shalom as wholeness, not mere quiet. Here, peace at the place of judgment means a courtroom where justice can actually be done because no one is too tired to think clearly.
The takeaway: structural reform is not a bureaucratic concession. It is a spiritual one. A judge who is at peace can see cases more clearly than a judge who is depleted.
