הגדרה (אנגלית)

The law that establishes that there is a prior right in the purchase of a field offered for sale to the owner of the adjoining field bordering the sold field, provided that he pays the accepted price (this law is based on the biblical statute appearing in Deuteronomy 21:18: "And you shall do what is right and good in the eyes of the LORD, that it may go well with you").

(“A gift is not subject to the law of the neighboring owner (bar metzra). Ameimar said: if he wrote a clause of responsibility (warranty) for it, then it is subject to the law of the neighboring owner. Likewise, the Rif ruled in a responsum that if a person comes with a claim of bar metzra against the seller’s sons, the claim is invalid, for the essence of the law of bar metzra is based on the verse ‘and you shall do what is right and good.’”)
