throwing an axe and cutting the difference between different foolish eating of holy things(debating the consequences of eating terumah if you are not a priest. if eaten by mistake over an olive size, pay the priest the amount plus a fifth. if intentional then no payment as punished by karet, a spiritual cutting off of the people. in the discussion R. Hiyya bar Avin accuses Rabba and Rav Sheshet of throwing an axe at his answer... the talmudic equivalent of throwing a spanner in the works)
