בראשית, פרק י״ח, פסוק ט״ז

A sharp transition takes place as the visitors leave the warmth of Abraham’s tent, a place defined by kindness and hospitality, and turn toward the corrupt city of Sodom. As they rise to depart from this house of giving [ספורנו, רד״ק], the group divides. Two of the three angels continue toward Sodom to destroy it, while the third, the greatest among them, remains behind to speak with Abraham in the name of God [רשב״ם, ביאור יש״ר, אברבנאל]. Some suggest their sudden departure is prompted by Sarah denying that she laughed; as beings of truth, the angels refuse to linger in a place where a falsehood is spoken [צרור המור]. Rather than vanishing instantly, they choose to walk away like ordinary men. This deliberate pace allows Abraham the opportunity to fulfill the commandment of escorting his guests [אלשיך].

As the men direct their gaze toward Sodom, they look down from a high place to a low place with a critical eye [רש ר הירש, ביאור יש״ר]. The primary approach among commentators is that whenever this specific type of downward look occurs in the Torah, it carries a negative meaning associated with disaster and destruction. The only exception is when such a look is connected to giving charity to the poor, an act powerful enough to turn strict justice and anger into mercy [רש״י, גור אריה, פענח רזא, הדר זקנים]. This highlights a massive gap between the two locations. The angels leave a home filled with giving and kindness, only to cast a destructive gaze upon Sodom, a city whose core sins are pride, selfishness, and cruelty toward the poor and passing travelers [ספורנו, מלבי״ם, רש ר הירש, חומש קה״ת].

Abraham walks alongside them to send them on their way [רד״ק, שד״ל, ביאור יש״ר]. Still unaware that his visitors are angels, he assumes they are ordinary men or prophets. He acts with common courtesy, stepping out to honor them and show how much he values their company [רש״י, מזרחי, שד״ל, גור אריה]. Beyond simple respect, Abraham knows the people of Sodom are hostile to travelers, so he escorts his guests to offer protection from the dangers of the city [מלבי״ם]. The proper distance a host should walk to escort a guest is considered to be about a mile [רד״ק, רבנו בחיי, צאינה וראינה]. Ultimately, Abraham's deep dedication to the commandment of escorting guests earns him a divine revelation, leading God to share His secret plans regarding the upcoming destruction of Sodom [רבנו בחיי, אברבנאל].
