(1) Hashem appeared/initiated communication (with) 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 men 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.
(16) The men set out from there and looked down toward Sodom, Abraham walking with them to see them off. (17) Now Hashem had said, “Shall I hide from Abraham what I am about to do, (18) since Abraham is to become a great and populous nation and all the nations of the earth are to bless themselves by him? (19) For I have singled him out, that he may instruct his children and his posterity to keep the way of Hashem by doing what is just and right, in order that Hashem may bring about for Abraham what has been promised him.” (20) Then Hashem said, “The outrage of Sodom and Gomorrah is so great, and their sin so grave! (21) I will go down to see whether they have acted altogether according to the outcry that has reached Me; if not, I will take note.”
(ח) ר' יהודה אומר, הכריזו בסדום כל מי שהוא מחזיק בפת לחם עני ואביון ישרף באש פליטת בתו של לוט היתה נשואה לאחד מגדולי העיר וראתה עני אחד מדקדק ברחוב העיר ועגמה נפשה עליו שנאמר עגמה נפשי לאביון מה עשתה בכל יום היתה יוצאה לשאוב היתה נותנת בכד שלה מכל מזון ביתה ומאכלת לאותו עני אמרו אנשי סדום העני הזה מאין הוא חי וכשידעו בדבר הוציאו אותה להשרף אמרה רבון כל העולמים עשה משפטי ודיני מאנשי סדום ועלתה צעקתה לפני כסא הכבוד באותה שעה אמר הב"ה ארדה נא ואראה אם כצעקת הנערה הזאת עשו אנשי סדום אהפוך יסודותיה למעלה ופניה למטה שנאמר ארדה נא ואראה הכצעקתה הבאה אלי עשו כלה הכצעקתם אין כתיב כאן אלא הכצעקתה.
(8) Rabbi Jehudah said: They made a proclamation in Sodom (saying): Everyone who strengthens the hand of the poor or the needy with a loaf of bread shall be burnt by fire. Peleṭith, daughter of Lot, was wedded to one of the magnates of Sodom. She saw a certain very poor man in the street of the city, and her soul was grieved on his account, as it is said, "Was not my soul grieved for the needy?" (Job 30:25). What did she do? Every day when she went out to draw water she put in her bucket all sorts of provisions from her home, and she fed that poor man. The men of Sodom said: How does this poor man live? When they ascertained the facts, they brought her forth to be burnt with fire. She said: Sovereign of all worlds ! Maintain my right and my cause (at the hands of) the men of Sodom. And her cry ascended before the Throne of Glory. In that hour the Holy One, blessed be He, said: "I will now descend, and I will see" (Gen. 18:21) whether the men of Sodom have done according to the cry of this young woman, I will turn her foundations upwards, and the surface thereof shall be turned downwards, as it is said, "I will now descend, and I will see whether they have done altogether according to her cry, which is come unto me" (ibid.). "According to their cry" is not written here (in the text), only "According to her cry."

(1) The two messengers arrived in Sodom in the evening, as Lot was sitting in the gate of Sodom. When Lot saw them, he rose to greet them and, bowing low with his face to the ground, (2) he said, “Please, my lords, turn aside to your servant’s house to spend the night, and bathe your feet; then you may be on your way early.” But they said, “No, we will spend the night in the square.” (3) But he urged them strongly, so they turned his way and entered his house. He prepared a feast for them and baked unleavened bread, and they ate. (4) They had not yet lain down, when the town council [and] the militia of Sodom—insignificant and influential alike, the whole assembly without exception—gathered about the house. (5) And they shouted to Lot and said to him, “Where are the men who came to you tonight? Bring them out to us, that we may be intimate with/humiliate.
...
(14) So Lot went out and spoke to his sons-in-law, who had married his daughters, and said, “Up, get out of this place, for Hashem is about to destroy the city.” But he seemed to his sons-in-law as one who jests.
(י) אַרְבַּע מִדּוֹת בָּאָדָם. הָאוֹמֵר שֶׁלִּי שֶׁלִּי וְשֶׁלְּךָ שֶׁלָּךְ, זוֹ מִדָּה בֵינוֹנִית. וְיֵשׁ אוֹמְרִים, זוֹ מִדַּת סְדוֹם. שֶׁלִּי שֶׁלְּךָ וְשֶׁלְּךָ שֶׁלִּי, עַם הָאָרֶץ. שֶׁלִּי שֶׁלְּךָ וְשֶׁלְּךָ שֶׁלָּךְ, חָסִיד. שֶׁלִּי שֶׁלִּי וְשֶׁלְּךָ שֶׁלִּי, רָשָׁע:
(10) There are four types of character in human beings: One that says: “mine is mine, and yours is yours”: this is a commonplace type; and some say this is a sodom-type of character. [One that says:] “mine is yours and yours is mine”: is an unlearned person (am haaretz); [One that says:] “mine is yours and yours is yours” is a pious person. [One that says:] “mine is mine, and yours is mine” is a wicked person.

(1) On Shabbat, one may move even four or five baskets of straw and baskets of produce, due to the guests, who require that place to sit, and due to suspension of Torah study in the study hall, where space is required to seat the students. However, one may not move these items to create space in the storeroom...
We may clear... If space is needed for guests for a meal, or for students to hear a Torah lecture, we are not concerned that this falls under the issue of extrenuous labor.
(א) ויאמר אדני אם נא מצאתי חן בעיניך אל נא תעבור מעל עבדך, ובגמרא (שבת דקכ"ז ע"א) גדולה הכנסת אורחין מהקבלת פני שכינה כו', שמעתי ממורי ביאור גדולה הכנסת אורחין מהקבלת פני השכינה, והקשה, והעולה שלפעמים הכנסת אורחין הוא ביטול תורה, או סיפורי לשון הרע וכו' מכל מקום גדולה הכנסת אורחים:
(תוי"י בסופו דר"ט ע"ב)
The Gemara says hosting guests is greater than greating the Shechina. I heard from my teacher clarified that hosting guests is greater than greeting the Shechina, yet this is very difficult, sometimes hosting guests can lead one towards nullifying from Torah study, or this can cause one to be engrossed in lashon hara. Nevertheless, we see how great hosting guests is.
“[he planted an eshel which is] a lodge” – for guests to stay and sleep.
The term eshel is an acronym for the Hebrew words: eating, drinking, and escorting guests on their way for he [Abraham] would feed them, offer them drink and then escort them on their travels.

(2) The reward one receives for accompanying guests is greater than all of the others. This is a statute which Abraham our Patriarch instituted and the path of kindness which he would follow. He would feed wayfarers, provide them with drink, and accompany them. Showing hospitality for guests surpasses receiving the Divine Presence as Genesis 18:3 states: "And he saw and behold there were three people."
Accompanying them is greater than showing them hospitality. Our Sages said: "Whoever does not accompany them is considered as if he shed blood."
(3) We compel people to accompany wayfarers in the same manner as we compel them to give charity. The court would prepare agents to accompany people who travel from place to place. If they were lax in this matter, it is considered as if they shed blood. Even a person who accompanies a colleague for four cubits will receive a great reward.
What is the extent to which a person must accompany a colleague? A teacher must accompany his student to the outskirts of the city. A person must accompany a colleague to the city's Sabbath limits. A student must accompany his teacher for a parsah. If he was his master teacher, he must accompany him until three parseot.
Zohar, Part 1 pg. 105b
When a person escorts his friend, he draws the Divine Presence (Shechina) down, which cleaves to his friend and protects him. Because of this, one must be careful to escort a guest …”
Chofetz Chaim, Ahavat Chesed 3:2
Especially if the guest is not familiar with the way, and the roads branch out in several directions, it is a great mitzvah to accompany him or at least clearly explain where to go so that he will not get lost.
Shlah Hakadosh (Chullun 117), Paraphrase
The Jewish People as a whole are referred to as ‘Knesset Yisrael,’ the word ‘knesset’ meaning a gathering. This alludes to the idea that although the Jewish People’s corporeal existence is divided into numerous bodies, our neshamot are ‘gathered’ together, unified and inseparable (all being hewn from the same Divine source).
When leaving a city, one enters a danger zone, as the Sages teach: “all of the roads are fraught with danger” (Yerushalmi Brachot 4:4.)
In such situations, we are given the mitzvah of escorting guests to bestows grace upon the traveller.
By accompanying him on his way, the city dwellers allude to the unification of the Jewish nation. In a sense they are telling their guest, even though you are leaving us, we are still connected. Thus their act accords the guest his status as part of the collective whole, which guarantees his protection for the remainder of the trip.
Maharal, Netivot Olam, Netiv Gemilut Chasadim, Ch. 5
When someone sets out on the way and others see him off, they in effect give honor to the Divine Image in which he was created. If people fail to do so, it is as if they had shed his blood [as is stated in Sotah 46b], for when one is robbed of the honor due to his Divine Image this is true bloodshed.
כימב״י הכהן:
הקב״ה בורא העולם לשם לנתן הנאה לבריאות שלו. הדרך לב״י למרגיש הנאה של אמתית, להולך בדרכו. (למשל, גודלת את הבנים.) הכנסת אורחים העבודה יותר טוב לעושה זאת. בני אדם עוסק ליוצר בית שלו, ואז הוא נותן משלו לאורחים, זה ההולך בדרכו ממש. ואז, אברהם אבינו לא עושה גנאי לשכינה, להיפוך, הוא מגלה השכינה בדרכו ומרגיש טובת הנאה של תכלית שלהם.
Cimby Hakohen:
Hashem created this world to give pleasure to His creatures. The greatest form of pleasure is to emulate Hashem's ways. (Having/raising a child for example.) One of the ultimate ways to do so is by hosting guests. The individual has toiled to create a living space for himself, and by extending this living space, and providing for others, he has mimicked Hashem's creation of the world. Therefore, when Avraham "departs" from conversing with the Shechina to opt to host the Angels, this is not a slight to the Shechina, rather the means to be more alike, and reveal, the Shechina, and attain a sense of purpose.
