R. Johanan said: you are not to appoint members of the Sanhedrin who are not men of stature, wisdom, good, old, who know sorcery, and who are fluent with all the seventy languages so that they have no need for interpretation. Rab Judah said in Rab’s name: do not appoint to the Sanhedrin people who cannot prove the cleanness of a reptile from the Tora . Rab said: ‘I can prove its cleanness’.
