אֵין בַּשַּׂר הַמֵּת מַרְגִּישׁ בָּאִזְמֵל

ביטוי (אנגלית)

Dead flesh does not feel the knife

הגדרה (אנגלית)

The dead cannot feel pain. By extension: A person in a most difficult situation is sometimes unaware of his condition and the harm being caused to him.

("Our Rabbis taught: Who wrote the Scroll of Fasts? They said: Hananiah ben Hezekiah and his group, who cherished suffering. Rabban Shimon ben Gamliel said: We too cherish suffering, but what can we do, for if we begin to write them, we cannot finish... Another explanation: Dead flesh does not feel the knife" - Shabbat 13b. Also: "And if one repents little by little, he is cleansed of his sin... But for one who is as if dead and does not feel the knife, so he does not feel his illness, his evil, and the distress of his soul" - Pele Yoetz/Letter T - Repentance.)
