Reference for Shabbat 229:5
אמר לך רב הונא ותסברא אימא סיפא טעונין גניזה השתא אצולי מצילינן גניזה מיבעי אלא רב הונא מתרץ לטעמיה ורב חסדא מתרץ לטעמיה רב הונא מתרץ לטעמיה בין שקורין בהם נביאים ובין שאין קורין בהם כתובים במה דברים אמורים שכתובין בלשון הקדש אבל בכל לשון אין מצילין ואפילו הכי גניזה בעו רב חסדא מתרץ לטעמיה בין שקורין בהן נביאים ובין שאין קורין בהן כתובים אע"פ שכתובין בכל לשון נמי מצילין והכי קאמר ומקק שלהן טעונין גניזה
We learnt: ALL SACRED WRITINGS MAY BE SAVED FROM THE FIRE, WHETHER WE READ THEM OR NOT, and even if they are written in any language. Surely WHETHER WE READ THEM refers to the Prophets, whilst OR NOT refers to the Writings, AND EVEN IF THEY ARE WRITTEN IN ANY LANGUAGE, though they may not be read [publicly], yet he [the Tanna] teaches that they MAY BE SAVED, which refutes R. Huna? — R. Huna can answer you: Is that logical? Consider the second clause: THEY MUST BE HIDDEN: seeing that they must be saved,<span class="x" onmousemove="('comment',' On your hypothesis. ');"><sup>13</sup></span> need hiding be mentioned?<span class="x" onmousemove="('comment',' Obviously if they have sufficient sanctity to be saved on the Sabbath they must not be simply thrown away when no longer fit for use. ');"><sup>14</sup></span> But R. Huna explains it in accordance with his view, while R. Hisda explains it according to his. R. Huna explains it in accordance with his view. WHETHER WE READ THEM, [i.e.] the Prophets; OR NOT, [i.e.,] the Writings. That is only if they are written in the Holy Tongue [Hebrew], but if they are written in any [other] language, we may not save them, yet even so they must be hidden. R. Hisda explains it according to his view: WHETHER WE READ THEM, [i.e.,] the Prophets, OR NOT, [i.e.,] the Writings; EVEN IF THEY ARE WRITTEN IN ANY LANGUAGE, we must still save them. And this is what he states: And [even] their worm-eaten [material] MUST BE HIDDEN.
