Refugees, Asylees, and Assorted Strangers

AND IF A STRANGER SOUJORN WITH THEE. Scripture mentions the stranger after the old man. It does so to, as it were, to say, as I warned you to respect the old Israelite because he has no strength, I warn you not to wrong the foreigner because you are stronger than he is, or who has no power because he is in your country and subject to you.

Yosef ben Yohanan, a man of Jerusalem, would say: Let your house be open to all, let the poor be members of your household, ... . (Pirkei Avot 1:5)
Let your house be open to all. How so? This teaches that a person’s house should be open to all sides: the south, the east, the west, and the north. This is like Job, who made four doors to his house. And why did Job make four doors to his house? So that the poor would not have to trouble themselves to go around the whole house. Someone who came in from the north would enter from that direction, and someone who came in from the south would enter from that direction, and so with every direction. That is why Job made four doors to his house.
Let the poor be members of your household. Not that they will be actual members of your household, but they will speak of what they ate and drank in your house, in the way that they speak of what they ate and drank in the house of Job. For when they would meet, one would say to another: Where are you coming from? (And the other would reply:) From the house of Job; and where are you going? (And the first one would say:) To the house of Job.
So when all the great tragedies came upon him, Job said before the Holy Blessed One: Did I not feed the hungry and give drink to the thirsty? as it says (Job 31:17), “Did I ever eat my food alone, and not let orphan eat from it?” And did I not clothe the naked? as it says (Job 31:20), “He warmed himself from the shearings of my sheep.” And even so, these tragedies came upon me. The Holy Blessed One said to Job: Job, you still have not gotten to [even half] the level of Abraham. You sit and wait in your house, and guests come in to you. And if it is someone’s custom is to eat wheat bread, you feed him wheat bread. And if someone’s custom is to eat meat, you feed him meat. And if someone’s custom is to drink wine, you pour him wine. But Abraham did not do this. Rather, he sat and looked out at the world, and when he would see potential guests, he would go bring them into his house. And if someone was not accustomed to eating wheat bread, he would feed him wheat bread. And if someone was not accustomed to eating meat, he would feed him meat. And if someone was not accustomed to drinking wine, he would pour him wine. Not only that, but he built large booths out on the roads, where he would leave food and drink, and anyone who came by and entered would eat and drink and bless the heavens, and he would feel content. Anything that one could ask for was available in the house of Abraham, as it says (Genesis 21:33), “And he planted an Eshel tree in Beer Sheba.”

He [Rabbi Tarfon] used to say: It is not your duty to finish the work, but neither are you at liberty to neglect it.
