'Neighbour' in the Bible

And he answering said, 'Thou shalt love the Lord thy God out of all thy heart, and out of all thy soul, and out of all thy strength, and out of all thy understanding, and thy neighbour as thyself.'

And he, willing to declare himself righteous, said unto Jesus, 'And who is my neighbour?'

'Who, then, of these three, seemeth to thee to have become neighbour of him who fell among the robbers?'
