A need for creative judges

Hi,

Preface: Vayikra 11:29-38 lists varieties of sheretz (crawling creatures) that are ritually impure.

"Rav Yehudah said, citing Rav: We only seat on the Sanhedrin (the highest rabbinical court) one who knows how to argue, from biblical sources, that a sheretz is ritually pure."

 אמר רב יהודה אמר רב: אין מושיבין בסנהדרין אלא מי שיודע לטהר את השרץ מן התורה.

(Talmud, Sanhedrin 17a)

Have a great day,
Mordechai
