another, fellow, neighbour

Dictionary of Biblical Words:

The law concerning the neighbor may be studied in Lev. 25 In the New Testament, however, an entirely new meaning is given to this word by our Lord’s parable of the good Samaritan, according to which my neighbor is any one to whom I can show mercy or kindness. Surely in this light we all have many neighbors.

From Manners and Customs of the Bible:

The Jews gave a very narrow definition of the word “neighbor.” The robbing interpreted it to mean only those who were of the Jewish people. The Gentiles were not considered neighbors.
