'Neighbour's' in the Bible

And thou shalt not lie carnally with thy neighbour's wife, to become unclean with her.

And a man that committeth adultery with a man's wife, who committeth adultery with his neighbour's wife, the adulterer and the adulteress shall certainly be put to death.

And if ye sell ought unto your neighbour, or buy of your neighbour's hand, ye shall not overreach one another.
