Reference for Chagigah 21:4

אלא לעולם כדרבא ודקא קשיא לך מידי דהוה אמוציא מעות הקדש לחולין התם מידע ידע דאיכא זוזי דהקדש איבעי ליה לעיוני הכא מי ידע היינו כהררין התלויין בשערה:

Rather, really it is like Rava [who said it is the case of the sender remembers and the messenger does not remember], and your difficulty that it should be something akin to the case of one who takes sacred money for ordinary uses [where, even by mistake, still makes the mistaken party guilty of misappropriation], there he knew there was a zuz of Temple property, and he should have investigated [to find out if he was being sent to misappropriate it]. Here [in Rava's case], does he know? [Yet he is guilty!] That is like a mountain hanging by a thread!
