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.
