"When the entire congregation errs..." (Leviticus 4:13), Hazal equates the following :
- "The entire congregation errs" ==> The Sanhedrin errs.
- The Sanhedrin ==> The entire Congregation of Israel.
The United States' of America's Congress, or the Canadian Parliament represent all of the the people. In the absence of such a representative body, then all of the people represent themselves.
