English: "Your hand shall release" — your hand shall release, but not one who delivers his documents to the court; therefore Hillel instituted the prozbul for the sake of the social order.
On the daf / in context: By transferring the debt to the court the creditor removes it from the category of a private claim that must be released; Hillel formalized this mechanism so that people would continue to lend.
Type of Learning
Derash on the verse (Gittin) — the scriptural basis of the prozbul.
What Is Learned
A debt that has been delivered to the court is not cancelled by shemittah; this is the foundation of Hillel’s prozbul ordinance.
