English: Might one think: if the beit din ruled and the beit din acted they are liable? The verse says “the assembly and they did” — the act depends on the assembly and the ruling on the beit din.
Separation of hora’ah and ma’aseh — the court rules; the people act — both are required.
Hora’ah belongs exclusively to the beit din; ma’aseh belongs exclusively to the kahal. If the judges themselves were the ones who performed the prohibited act, the verse’s structure would not be satisfied. The division of labor is essential to the formation of communal liability.
