Reference for Bava Kamma 129:1

אין לי אלא ידו גגו חצירו וקרפיפו מנין ת"ל (שמות כב, ג) אם המצא תמצא מ"מ

this gives me the rule only as applying to his hand. Whence do I learn that it applies to his roof, his courtyard and his enclosure? It distinctly lays down: <i>If to be found it be found</i> [i.e.] in all places'?<span class="x" onmousemove="('comment',' B.M. 10b and 56b. ');">¹</span> — But if so<span class="x" onmousemove="('comment',' That it was meant to imply only one point. ');">²</span>
