תּלמוד אויף זכריה 13:6

Rebbi Yehudah said forty full... etc. between his shoulders.: Rebbi Yitzchak said, What is the reason of Rebbi Yehuda? That it is written (Zechariah 13,6) "What are these wounds between your hands? And he will say that I was hit in the house of those who loved me." And according to the Rabbis? [Who say that there is no fortieth lash which would be administered between the shoulders.] That verse is referring to the schoolchildren.
