When a robbed object remains unchanged, what must the robber do even if the owner already despaired?
Halacha 1: When an object taken by robbery remains unchanged, it must be returned to its original owner even after the owner despaired.
Question 2
If the robber sold the stolen object after the owner despaired, must the purchaser return it?
Halacha 2: If the robber sold the article after the owner despaired, the purchaser need not return it; the robber must pay the owner.
Question 3
Why did the Sages rule that a repentant robber need only pay the original value even if the stolen object increased in value?
Halacha 5: The Sages limited repayment to original value to encourage repentance, not discouraging return by demanding enhanced value.
Question 4
A robber takes boards and nails them into a structure. Has he acquired the boards?
Halacha 9: A reversible change does not confer ownership. Boards nailed together can be disassembled, so the robber has not acquired them.
Question 5
If a robber grinds stolen wheat into flour, has he acquired it?
Halacha 11: Irreversible transformation (like grinding wheat to flour) constitutes a change that transfers ownership — the robber pays the wheat's value.
