יב ואיבעית אימא הכי קאמר ליה הא אנא דסבירא לי כרבי יוסי הגלילי דאמר מנה צורי והא סהדי דמסהדי בך זיל הב ליה מנה צורי
12 What is the meaning of, 'Here I am, and here is also R. Jose the Galilean'? If you say he meant, 'Here I am who witnessed you [doing this] and here is also R. Jose the Galilean who holds that the payment should be a Tyrian <i>maneh</i>; go therefore and thus pay him a Tyrian maneh', would this not imply that a witness is eligible to act [also] as judge? But [how can this be, since] it was taught: If the members of the Sanhedrin saw a man killing another, some of them should act as witnesses and the others should act as judges: this is the opinion of R. Tarfon. R. Akiba [on the other hand] said that all of them are considered witnesses and [they thus cannot act as judges, for] a witness may not act as a judge.<span class="x" onmousemove="('comment',' Sanh. 34b; B.B. 114a.
