When Jesus said to love your neighbor, a lawyer who was present asked him to clarify what he meant by neighbor. He wanted a legal definition he could refer to in case the question of loving one ever happened to come up. He presumably wanted something on the order of: "A neighbor (hereinafter referred to as the party of the first part) is to be construed as meaning a person of Jewish descent whose legal residence is within a radius of no more than three statute miles from one's own legal residence unless there is another person of Jewish descent (hereinafter to be referred to as the party of the second part) living closer to the party of the first part than one is oneself, in which case the party of the second part is to be construed as neighbor to the party of the first part and one is oneself relieved of all responsibility of any sort or kind whatsoever."
Instead, Jesus told the story of the Good Samaritan (Luke 10:25-37), the point of which seems to be that your neighbor is to be construed as meaning anybody who needs you. The lawyer's response is left unrecorded.
