'Neighbour' in the Bible

And Saul is called, and all the people who are with him, and they come in unto the battle, and, lo, the sword of each hath been against his neighbour -- a very great destruction.

And Samuel saith unto him, 'Jehovah hath rent the kingdom of Israel from thee to-day, and given it to thy neighbour who is better than thou;

And Jehovah doth for Himself as He hath spoken by my hand, and Jehovah rendeth the kingdom out of thy hand, and giveth it to thy neighbour -- to David.
