Reference for Pesachim 45:12

והרי חמץ דרחמנא אמר לא יאכל חמץ ותניא ר' יוסי הגלילי אומר תמה על עצמך היאך חמץ אסור בהנאה כל שבעה שאני התם דאמר קרא (שמות יג, ז) ולא יראה לך שאור שלך יהא

- Here it is different, because Scripture saith, and they shall be [a detestable thing]:<span class="x" onmousemove="('comment',' Lev. XI, 11.');">²³</span> [meaning.] they shall be in their [forbidden] state. Now according to Hezekiah, for what purpose is 'shall not be eaten' written-so that 'unto you' is adduced to teach that it is permitted; let the Merciful One not write 'shall not be eaten,' so that 'unto you' will be unnecessary? - Hezekiah can answer you: My opinion<span class="x" onmousemove="('comment',' Lit., 'reason'.');">²⁴</span>
