How is this so? If [the buyer] drew the produce away from [the seller] but did not give over the money, he cannot retract. If [the buyer] gave the money but did not draw the produce away from [the seller], he can retract. But they said: “He that exacted punishment from the generation of the flood and the generation of the dispersion (at the time of the Tower of Babel) will exact punishment from one who does not keep by his word. Rabbi Shimon says: “He that has the money has the upper hand.”

There are five cases in which one must add a fifth:One who eats terumah, or the terumah taken from the tithe, or the terumah from a tithe taken from doubtfully tithed produce, or dough offering, or first fruits, must add a fifth [to the value of the principle when he makes restitution]. One that redeems [the fruit of] a fourth year plant, or his second tithe, must add a fifth. One that redeems that which he dedicated [to the Temple] must add a fifth. One that derives a perutah’s worth of benefit from that which belongs to the sanctuary must add a fifth [when he makes restitution]. One who steals that which is worth a perutah from his fellow must add a fifth [when he makes restitution].

Once in thirty days prices were fixed [on behalf of] the chamber. Anyone who had accepted upon himself to supply fine flours at four [se'ahs for a sela] and they now stood at three [se'ahs for a sela] he must [still] supply four. [If he had accepted to supply fine flours] at three [se'ahs for a sela] and they now stood at four, he must [also] supply at four, for the sanctified property has the upper hand. If the fine flour became worm-eaten the loss is his; if the wine became sour the loss is his. For he is not entitled to his money until the altar has accepted [the offering].
