Jesus' answer was that of two men who were on a journey. They were not from the same place. One was from Jerusalem, the other one was a Samaritan. The Samaritan came to where the man from Jerusalem lay wounded by the robbers who had stripped him of his possessions. The Samaritan showed sympathy for the fellow traveler.
Many enemies live in the same neighborhood of a good neighbor.
There were many other proofs in the Bible which agree with the above answer. 6 Love yourself and your kind. Let us refrain from doing evil to each other, and let us love each other as brothers, as we are the same flesh and blood. In this way, you and I will not have any trouble in uniting. It is a fool who does not love himself and his people.
