The Talmud derives from Avraham's actions in Vayeira that 'hachnasas orchim is greater than kabbalat pnei haShechinah' — Avraham left off receiving the Divine Presence in order to welcome his guests, teaching that active chesed toward human beings takes precedence even over direct communion with God.
מִפְּנֵי הָאוֹרְחִין וְכוּ׳. אָמַר רַבִּי יוֹחָנָן: גְּדוֹלָה הַכְנָסַת אוֹרְחִין כְּהַשְׁכָּמַת בֵּית הַמִּדְרָשׁ, דְּקָתָנֵי: ״מִפְּנֵי הָאוֹרְחִין וּמִפְּנֵי בִּטּוּל בֵּית הַמִּדְרָשׁ״. וְרַב דִּימִי מִנְּהַרְדְּעָא אָמַר: יוֹתֵר מֵהַשְׁכָּמַת בֵּית הַמִּדְרָשׁ, דְּקָתָנֵי ״מִפְּנֵי הָאוֹרְחִין״, וַהֲדַר ״וּמִפְּנֵי בִּטּוּל בֵּית הַמִּדְרָשׁ״. אָמַר רַב יְהוּדָה אָמַר רַב: גְּדוֹלָה הַכְנָסַת אוֹרְחִין מֵהַקְבָּלַת פְּנֵי שְׁכִינָה, דִּכְתִיב: ״וַיֹּאמַר ה׳ אִם נָא מָצָאתִי חֵן בְּעֵינֶיךָ אַל נָא תַעֲבֹר וְגוֹ׳״. אָמַר רַבִּי אֶלְעָזָר: בֹּא וּרְאֵה שֶׁלֹּא כְּמִדַּת הַקָּדוֹשׁ בָּרוּךְ הוּא מִדַּת בָּשָׂר וָדָם. מִדַּת בָּשָׂר וְדָם, אֵין קָטָן יָכוֹל לוֹמַר לַגָּדוֹל ״הַמְתֵּן עַד שֶׁאָבֹא אֶצְלְךָ״, וְאִילּוּ בְּהַקָּדוֹשׁ בָּרוּךְ הוּא כְּתִיב ״וַיֹּאמַר ה׳ אִם נָא מָצָאתִי וְגוֹ׳״.
We learned in the mishna: One may move baskets of produce due to the guests and in order to prevent the suspension of Torah study in the study hall. Rabbi Yoḥanan said: Hospitality toward guests is as great as rising early to go to the study hall, as the mishna equates them and teaches: Due to the guests and due to suspension of Torah study in the study hall. And Rav Dimi from Neharde’a says: Hospitality toward guests is greater than rising early to the study hall, as it teaches: Due to the guests, and only afterward: And due to suspension of Torah study in the study hall. 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. Rabbi Elazar said: Come and see that the attribute of the Holy One, Blessed be He, is not like that of flesh and blood. The attribute of flesh and blood people is such that a less significant person is unable to say to a more significant person: Wait until I come to you, while with regard to the Holy One, Blessed be He, it is written: “And he said: Lord, if now I have found favor in Your sight, please pass not from Your servant.” Abraham requested that God wait for him due to his guests.
