What biblical principle underlies the law of bar metzra (neighbor's right of first refusal)?
The Rambam derives bar metzra from the verse 'do what is right and good' — it is an ethical obligation requiring fair dealing with one's neighbor.
Question 2
Does the right of bar metzra apply when property is rented (not sold)?
Bar metzra applies only to sales, not to rentals — a neighbor cannot displace a tenant or demand to rent the property instead.
Question 3
A seller sells his field to a gentile. What consequence does the seller face?
The seller is placed under a communal ban of ostracism until he accepts personal financial responsibility for any harm the gentile neighbor causes to the Jewish neighbors.
Question 4
Can a neighbor exercise bar metzra to displace a purchaser who is an orphan?
Orphans are protected from displacement through bar metzra — the hardship and vulnerability of minors outweighs the neighbor's right to acquire the adjacent property.
Question 5
When land is owned by one person and the trees on it are owned by another, who has bar metzra rights when the land is sold?
When the land and trees have separate owners, the owner of the land is treated as the neighbor for bar metzra purposes — land ownership is the defining factor.
