When a foreigner resides among you in your land, do not mistreat them. The foreigner residing among you must be treated as your native-born. Love them as yourself, for you were foreigners in Egypt. Leviticus 19:33-34
He defends the cause of the fatherless and the widow, and loves the foreigner residing among you, giving them food and clothing. And you are to love those who are foreigners, for you yourselves were foreigners in Egypt. Deuteronomy 10:18-19
No stranger had to spend the night in the street, for my door was always open to the traveler Job 31:32
For I was hungry and you gave me something to eat, I was thirsty and you gave me something to drink, I was a stranger and you invited me in, I needed clothes and you clothed me, I was sick and you looked after me, I was in prison and you came to visit me. Matthew 25:25-36
For the entire law is fulfilled in keeping this one command: "Love your neighbor as yourself." Galatians 5:14
He asked Jesus, "And who is my neighbor?"
In reply, Jesus said: "A man was going down from Jerusalem to Jericho, when he was attacked by robbers. They stripped him of his clothes, beat him and went away, leaving him half dead. A priest happened to be going down the same road, and when he saw the man, he passed by on the other side. So too, a Levite, when he came to the place and saw him, passed by on the other side. But a Samaritan, as he traveled, came where the man was; and when he saw him, he took pity on him. He went to him and bandaged his wounds, pouring on oil and wine. Then he put the man on his own donkey, brought him to an inn and took care of him. The next day he took out two denarii and gave them to the innkeeper. 'Look after him,' he said, 'and when I return, I will reimburse you for any extra expense you may have.'
"Which of these three do you think was a neighbor to the man who fell into the hands of robbers?"
The expert in the law replied, "The one who had mercy on him."
Jesus told him, "Go and do likewise." Luke 10:29-37
