Reference for Pesachim 11:10
שאני הכא דאפקיה רחמנא בלשון לא ימצא מי שמצוי בידך יצא זה שאינו מצוי בידך
Shall we say that renting confers a title?<span class="x" onmousemove="('comment',' So that the house becomes legally the non-Jew's.');"><sup>17</sup></span> But surely we learned: Even in the place where they [the Sages] permitted renting [to a heathen], they did not permit [renting] for a dwelling-house, because he [the heathen] introduces [his] idols therein.<span class="x" onmousemove="('comment',' A.Z. 21a.');"><sup>18</sup></span> Now if you should think that renting confers a title, when he introduces [the idols] he introduces [them] into his own house? - Here it is different, because the Divine Law expresses it in the form of 'there shall not be found', [implying] that which is found in your hand [is forbidden], which excludes this [case], since it is not found in your hand.
