[If] one said to another, “I am selling you a beis kor of earth,” [and] it contained cervices ten handbreadths deep, or rocks ten handbreadths high, they are not measured with it; [if they were] less than this, they are measured with it. If he said to him, “[I am selling you] like a beis kor of earth,” even if it contained crevices deeper than ten handbreadths, or rocks higher than ten handbreadths, they are measured with it.

[If one said to another,] “I am selling you a beis kor of earth, as measured by a rope,” [if] he gave [even] the slightest amount less he must deduct; [if] he gave [even] the slightest amount more he must give back. If he said, “whether less or more,” even if he gave a quarter-kav less per seah or a quarter-kav more per seah, it becomes his. [If it was] more than this, he should make a reckoning. What does he give back? Money. But if [the seller] prefers, he gives him back the land. Why did they say that he gives back money? To improve the position of the seller. So that if there remained an area of nine kavs in the field, or half a kav in a garden —- or a quarter-kav according to R' Akiva —- he may give him back the land. Moreover, it is not only the quar-ter-kav that he gives back, but all the excess.

[If he said,] “I am selling you ... as measured by a rope, be it less or more,” [the condition] “be it less or more” negates [the condition of] “as measured by a rope.” [If he said,] “... be it less or more, as measured by a rope,” [the condition] “as meas-ured by a rope” negates [the condition] “be it less or more”; [these are] the words of Ben Nanas.  [If he described it] by its marks and boundaries: [if the difference is] less than a sixth, he must accept it; [but anything] down to a sixth, he deducts.

[If] one says to another, “I am selling you half the field,” they divide [the field] between them qualitatively, and he takes half his field. [If he said,] “I am selling you its southern half,” they divide [the field] between them qual-itatively, and he takes [equal to] its southern half. He accepts upon himself the place for the fence, a [wide] ditch, and a narrow ditch. How wide is a [wide] ditch? Six handbreadths. And the narrow ditch? Three [handbreadths].
