The Greek and Hebrew that is translated in English as “love your neighbor as yourself” is translated in Shilluk, Anuak, and Nuer as “love your neighbors as yourselves.” In those and other languages a plural form has to be used if it is to be applied to more than one person where in English a singular can stand for many (compare everyone, each, whoever, any).
