When Money Works

In order to finalize a transaction on objects that are not real estate, it is not sufficient to pay money alone. Some symbolic action of acquisition such as pulling the object into the domain of the purchaser is necessary to finalize the transaction and render retraction impossible.

An analysis of why this is so will help us understand when and why there is an exception to this rule. One of these exceptions deals with meat for the holidays and the other with food for an eiruv.

Four times a year there is a great demand for meat: the days preceding Pesach, Shavuot, Rosh Hashana and Shmini Atzeret. If someone gave some money to an animal merchant as payment for even one dinar’s worth of meat in an animal worth a thousand dinars, the seller cannot back out of the deal for lack of sufficient customers, and is compelled to slaughter that animal in order to fulfill his obligation resulting from the transaction finalized through money alone.

Rabbi Yochanan explains this in the following way. By Torah law money given in a transaction finalizes it and denies the ability to retract. The Sages, however, were concerned that if the buyer made no effort to pull his acquisition out of the seller’s domain, a situation could arise of a fire breaking out in the area of the seller with him making no effort to save the goods which he no longer owns. They therefore decreed that these goods leave his ownership only after the buyer has physically taken them into his custody. Since the Sages were interested in a Jew having greater access to meat before the above-mentioned holidays, they suspended this decree and allowed money to serve as the finalizer of the transaction.

What the Sages Say

“There is always room in the belly for tasty food.”

- Rabbi Yosef quoting a folk saying as to why we eat more on Shabbat than on weekdays
