'Neighbor' in the Bible

Owe no man anything, save to love one another: for he that loveth his neighbor hath fulfilled the law.

For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not covet, and if there be any other commandment, it is summed up in this word, namely, Thou shalt love thy neighbor as thyself.

Love worketh no ill to his neighbor: love therefore is the fulfilment of the law.

Let each one of us please his neighbor for that which is good, unto edifying.
