All English translations of the Gospels use this word (with or without the 'u') in Jesus second commandment but who was he referring to? In English is could mean anyone from the people who live next door to everyone on earth. Where do you draw the line?
Everyone is our neighbor. We know this because we are to compare this word where it is used in the whole Bible (1Corinthians 2:13). In (Luke 10:29) Jesus was asked the same question and His answer was in the next verses about the Good Samaritan.
