English: “You shall not spare and you shall not conceal him” — It was taught: One may not seat on the Sanhedrin an elderly man, a eunuch, or one who has no children; Rabbi Yehudah adds even a cruel man. The opposite is true for a mesis.
On the daf / in context: The composition of the court is adjusted for the mesis case: traits that would normally disqualify a judge for excessive severity become desirable.
Type of Learning
Derash on the verse (Sanhedrin) — the court for a mesis is deliberately composed of sterner judges.
What Is Learned
For a mesis the Sanhedrin is seated with the opposite qualifications of those required for ordinary capital cases.
