Then, a doctor of the law stood up and said to him in order to test him, “Master, what must I do to possess eternal  life?” Jesus answered  him, “What is it that is written in the Law? What have you read in it?” He responded to him, “You shall love the Lord your God with all your heart, with all your soul, withall your strength, and with all your mind, and your neighbor as yourself.” Jesus said to him, “You have answered well; do so and you shall live.”

However, wanting to appear to be righteous, the man said to Jesus, “And who is my neighbor?” And Jesus answering  said to him:

“A certain  man was coming down from Jerusalem to Jericho and fell into the hands of thieves, who stripped him of his clothes, covered him with wounds and left him half-dead. Afterward, it just so happened that a priest was coming down by the same way, and having noticed him, passed him by on the other side. A Levite, who also came to the same spot, saw him but passed by on the other side. But when a Samaritan, who was on a journey, came to where the man was and saw him, he was touched with great compassion. He approached him and poured oil and wine on his wounds and bandaged them. And putting him on his own animal, took him to an inn and cared for him. The following day, he took two silver coins and gave them to the innkeeper, saying, ‘Take good care of this man and whatever more you spend I will repay you when I return.’

“Which of these three seems to you to have been the neighbor of the one who fell into the hands of the thieves?” The doctor of the law responded to him, “The one who showed compassion on him.” Jesus said to him “Go and do likewise.” (Lk. 10:25-37)
