Hospitality, hachnassat orchim in Hebrew, is viewed by our tradition as an important mitzvah. For example:
אמר רב יהודה אמר רב גדולה הכנסת אורחין מהקבלת פני שכינה דכתיב ויאמר (ה׳) אם נא מצאתי חן בעיניך אל נא תעבר וגו׳... אמר רב יהודה בר שילא אמר רבי אסי אמר רבי יוחנן ששה דברים אדם אוכל פירותיהן בעולם הזה והקרן קיימת לו לעולם הבא ואלו הן הכנסת אורחין וביקור חולים ועיון תפלה והשכמת בית המדרש והמגדל בניו לתלמוד תורה והדן את חברו לכף זכות
Rav Yehuda said that Rav said on a related note: Hospitality toward guests is greater than receiving the Divine Presence, as when Abraham invited his guests it is written: “And he said: Lord, if now I have found favor in Your sight, please pass not from Your servant” (Genesis 18:3). Abraham requested that God, the Divine Presence, wait for him while he tended to his guests appropriately. ... Rav Yehuda bar Sheila said that Rabbi Asi said that Rabbi Yoḥanan said: There are six matters a person enjoys the profits of in this world, and nevertheless the principal exists for him for the World-to-Come, and they are: Hospitality toward guests, and visiting the sick, and consideration during prayer, and rising early to the study hall, and one who raises his sons to engage in Torah study, and one who judges another favorably, giving him the benefit of the doubt.
In ancient times and in the middle ages, Jewish travelers would often arrive in a town or a village without having made arrangements for food or lodging. Not every town had an inn and not every traveler could afford to pay for an inn even if there was one. Jewish families often offered these travelers meals and accommodations. The mitzvah of hachnassat orchim, as the Talmud and traditional commentators understand it, is based on this reality.
These days, we don't typically welcome strangers into our homes. (In our community, this can happen, for example, if the "travelers" are Shabbat observant and are attending a family celebration, someone living within walking distance to the synagogue might volunteer to host. But these guests are hardly strangers in this case).
So what does the mitzvah really mean to us today?
We may not be hosting complete strangers in our homes very often, but many of us do have other people over, especially on holidays like Thanksgiving. These people may be family, friends, friends of friends, or even family of family. Many of us also are guests in other people's homes. So what does it mean fulfill the part of the mitzvah of hachnassat orchim that involves being a good host or a good guest?
Let's look back at the story of Abraham and Sarah and the angels? In what ways do Abraham and Sarah model what it means to be a good host?
(א) וַיֵּרָ֤א אֵלָיו֙ יְהֹוָ֔ה בְּאֵלֹנֵ֖י מַמְרֵ֑א וְה֛וּא יֹשֵׁ֥ב פֶּֽתַח־הָאֹ֖הֶל כְּחֹ֥ם הַיּֽוֹם׃ (ב) וַיִּשָּׂ֤א עֵינָיו֙ וַיַּ֔רְא וְהִנֵּה֙ שְׁלֹשָׁ֣ה אֲנָשִׁ֔ים נִצָּבִ֖ים עָלָ֑יו וַיַּ֗רְא וַיָּ֤רׇץ לִקְרָאתָם֙ מִפֶּ֣תַח הָאֹ֔הֶל וַיִּשְׁתַּ֖חוּ אָֽרְצָה׃ (ג) וַיֹּאמַ֑ר אֲדֹנָ֗י אִם־נָ֨א מָצָ֤אתִי חֵן֙ בְּעֵינֶ֔יךָ אַל־נָ֥א תַעֲבֹ֖ר מֵעַ֥ל עַבְדֶּֽךָ׃ (ד) יֻקַּֽח־נָ֣א מְעַט־מַ֔יִם וְרַחֲצ֖וּ רַגְלֵיכֶ֑ם וְהִֽשָּׁעֲנ֖וּ תַּ֥חַת הָעֵֽץ׃ (ה) וְאֶקְחָ֨ה פַת־לֶ֜חֶם וְסַעֲד֤וּ לִבְּכֶם֙ אַחַ֣ר תַּעֲבֹ֔רוּ כִּֽי־עַל־כֵּ֥ן עֲבַרְתֶּ֖ם עַֽל־עַבְדְּכֶ֑ם וַיֹּ֣אמְר֔וּ כֵּ֥ן תַּעֲשֶׂ֖ה כַּאֲשֶׁ֥ר דִּבַּֽרְתָּ׃ (ו) וַיְמַהֵ֧ר אַבְרָהָ֛ם הָאֹ֖הֱלָה אֶל־שָׂרָ֑ה וַיֹּ֗אמֶר מַהֲרִ֞י שְׁלֹ֤שׁ סְאִים֙ קֶ֣מַח סֹ֔לֶת ל֖וּשִׁי וַעֲשִׂ֥י עֻגֽוֹת׃ (ז) וְאֶל־הַבָּקָ֖ר רָ֣ץ אַבְרָהָ֑ם וַיִּקַּ֨ח בֶּן־בָּקָ֜ר רַ֤ךְ וָטוֹב֙ וַיִּתֵּ֣ן אֶל־הַנַּ֔עַר וַיְמַהֵ֖ר לַעֲשׂ֥וֹת אֹתֽוֹ׃ (ח) וַיִּקַּ֨ח חֶמְאָ֜ה וְחָלָ֗ב וּבֶן־הַבָּקָר֙ אֲשֶׁ֣ר עָשָׂ֔ה וַיִּתֵּ֖ן לִפְנֵיהֶ֑ם וְהֽוּא־עֹמֵ֧ד עֲלֵיהֶ֛ם תַּ֥חַת הָעֵ֖ץ וַיֹּאכֵֽלוּ׃
(1) יהוה appeared to him by the terebinths of Mamre; he was sitting at the entrance of the tent as the day grew hot. (2) Looking up, he saw three figures standing near him. Perceiving this, he ran from the entrance of the tent to greet them and, bowing to the ground, (3) he said, “My lords! If it please you, do not go on past your servant. (4) Let a little water be brought; bathe your feet and recline under the tree. (5) And let me fetch a morsel of bread that you may refresh yourselves; then go on—seeing that you have come your servant’s way.” They replied, “Do as you have said.” (6) Abraham hastened into the tent to Sarah, and said, “Quick, three seahs of choice flour! Knead and make cakes!” (7) Then Abraham ran to the herd, took a calf, tender and choice, and gave it to a servant-boy, who hastened to prepare it. (8) He took curds and milk and the calf that had been prepared and set these before them; and he waited on them under the tree as they ate.
What other "obligations" of a good host would you add to this list?
What are some ways we can make sure we are good guests when someone else extends their hospitality? Here is a teaching from the Talmud.
הוּא הָיָה אוֹמֵר: אוֹרֵחַ טוֹב מַהוּ אוֹמֵר? — כַּמָּה טְרָחוֹת טָרַח בַּעַל הַבַּיִת בִּשְׁבִילִי, כַּמָּה בָּשָׂר הֵבִיא לְפָנַי, כַּמָּה יַיִן הֵבִיא לְפָנַי, כַּמָּה גְּלוּסְקָאוֹת הֵבִיא לְפָנַי, וְכׇל מַה שֶּׁטָּרַח — לֹא טָרַח אֶלָּא בִּשְׁבִילִי. אֲבָל אוֹרֵחַ רַע מַהוּ אוֹמֵר? — מַה טּוֹרַח טָרַח בַּעַל הַבַּיִת זֶה? פַּת אַחַת אָכַלְתִּי, חֲתִיכָה אַחַת אָכַלְתִּי, כּוֹס אֶחָד שָׁתִיתִי, כׇּל טוֹרַח שֶׁטָּרַח בַּעַל הַבַּיִת זֶה — לֹא טָרַח אֶלָּא בִּשְׁבִיל אִשְׁתּוֹ וּבָנָיו.
Ben Zoma would say: A good guest, what does he say? How much effort did the host expend on my behalf, how much meat did the host bring before me. How much wine did he bring before me. How many loaves [geluskaot] did he bring before me. All the effort that he expended, he expended only for me. However, a bad guest, what does he say? What effort did the host expend? I ate only one piece of bread, I ate only one piece of meat and I drank only one cup of wine. All the effort that the home owner expended he only expended on behalf of his wife and children.
What would you add to Ben Zoma's list?
