The Parable of the Good Samaritan
One Jew, a lawyer, desiring to justify himself since the Jews considered "their neighbours" to be only Jews and all others to be held in contempt asked Jesus Christ, "And who is my neighbour?"
In order to teach people to consider every other person as their neighbour, no matter who he might be of whatever nationality, or descent, or belief; and also that we must be compassionate and merciful to all people, doing what we can to help those in need and misfortune, Jesus Christ answered him with a parable.
"A man (a Jew) was going down from Jerusalem to Jericho, and he fell among robbers who stripped him and beat him, and departed leaving him half-dead. Now by chance, a priest was going down that road; and when he saw him, he passed by on the other side, So likewise a Levite (a Jewish church official), when he came to the place and saw him, he passed by on the other side."
"But a Samaritan, as he journeyed, came to where he was (The Jews despised the Samaritans so much that they would not have sat at the same table with them and even tried to avoid speaking to them). When the Samaritan saw him covered with wounds, he had compassion on him. He went to him and bound up his wounds pouring on them oil and wine. Then, he set him on his own beast and brought him to an inn, and took care of him. And the next day he took out two denarii (denarius was a Roman silver coin) and gave them to the innkeeper saying, 'Take care of him; whatever more you spend, I repay you when I come back."
Then, Jesus Christ asked the lawyer, "Which of these three do you think was a neighbour to the man fell among the robbers?"
The lawyer replied, "the one who showed mercy on him (that is, the Samaritan)."
And Jesus Christ said to him, "Go and do likewise."
