Akiba, who said [in regard to a field with a well in it] that the seller interprets the terms of the sale liberally.<span class="x" onmousemove="('comment',' Lit., 'he sells with a kindly eye,' i.e., if a man owns a courtyard or a field with a well in it, and sells the courtyard but not the well, he does not ipso facto retain a right of way through the courtyard or the field to the well, but has to pay for it, if required, to the purchaser. V. infra 64a. ');"><sup>7</sup></span>
