If
the buyer gave the seller the money but did not take the produce from
him, either party can legally renege, but the Sages said, “The One Who
exacted retribution from the people of the Generation of the Flood and
from the Generation of Dispersion – He will ultimately exact
retribution from someone who does not abide by his word!”
Abaye says that the court informs him about the retribution, and Rava says that the court actually pronounces the curse.
When
one makes a partial payment on movable property, Rav says that he
acquires only an amount equal to its value, but Rabbi Yochanan says
that he acquires the entire purchase.
