ת"ר גניבו אלף ושוה חמש מאות נמכר וחוזר ונמכר גניבו חמש מאות ושוה אלף אינו נמכר כלל ר' אליעזר אומר אם היה גניבו כנגד ממכרו נמכר ואם לאו אינו נמכר
for his theft': having been sold once, he may not be sold again! - Said Raba: There is no difficulty: the latter refers to one theft, the former to two thefts Abaye demurred: 'for his theft' may imply even many thefts!<span class="x" onmousemove="('comment',' 'Theft' being understood generically.');"><sup>12</sup></span> But, said Abaye, there is no difficulty; the latter refers to one man, the former to two men.<span class="x" onmousemove="('comment',' If he robs one man, even twice, and is charged with both thefts simultaneously, he can only be sold once. But if he robs two men, each of whom sues him at court at different times, he may be sold twice. Tosaf. reverses it.');"><sup>13</sup></span>
