Reference for Yevamot 230:2
ההוא גברא דאפקיד שומשמי גבי חבריה אמר ליה הב לי שומשמי אמר ליה שקילתינהו והא כן וכן הויין ובחביתא רמיין א"ל דידך שקלתינהו והני אחריני נינהו
A man once deposited some sesame with another, [and when in due course] he asked him, 'Return to me my sesame, the other replied. 'You have already taken it'. 'But, surely'. [the depositor remonstrated, 'the quantity] was such and such and it is [in fact still] lying [intact] in your jar'.<span class="x" onmousemove="('comment',' Which should prove that the sesame had not been returned to its owner. ');"><sup>4</sup></span> 'Yours', the other replied. 'you have taken back and this is different'. R. Hisda at first intended to give his decision [that the law in this case is] the same as that of the two learned men,<span class="x" onmousemove="('comment',' Whose wives Rabbi permitted to marry on the assumption that the discovered bodies were theirs. ');"><sup>5</sup></span> where we do not assume that those have gone elsewhere and these are others.<span class="x" onmousemove="('comment',' Who have the same identification marks. Similarly with the sesame in the jar, since it is of the same quantity as that of the deposited sesame it should be assumed to belong to the depositor and should, therefore, be returned to him.
