Rashi
שני TWO — One to destroy Sodom, the other to rescue Lot — it was he who had come to heal Abraham — whilst the third, who had come to make the announcement to Sarah, had departed as soon as he had carried out his mission (Midrash Tanchuma, Vayera 8).
Rashi
המלאכים ANGELS — But elsewhere (Genesis 18:2) Scripture calls them men! When the Divine Presence was with them, it speaks of them as men. Another explanation is: in connection with Abraham whose power to receive heavenly visitors was great and whom angels visited as regularly as men, it calls them men, but in connection with Lot it calls them angels (Genesis Rabbah 50:2).
Rashi
בערב AT EVENTIDE — Did it, however, take the angels such a long time to travel from Hebron to Sodom? But they were angels of mercy and so they tarried — perhaps Abraham would succeed in his advocacy for them (Genesis Rabbah 50:1).
Rashi
ולוט ישב בשער סדום AND LOT WAS SITTING IN THE GATE OF SODOM — The word is written without a ו so that it may be read יָשַׁב (he sat) — because that day they had appointed him as their judge (Genesis Rabbah 50:3).
Rashi
'וירא לוט וגו AND LOT SAW THEM etc. — From the practice in Abraham’s house he had learned to look out for strangers (Genesis Rabbah 50:4).
Rashi
לו ישטמנו means PERHAPS HE WILL HATE US. The word has many different meanings. There are examples of לו used to denote a petition, having the meaning of “Oh that!” as for instance: (Genesis 30:34) “Would (לו) it might be according to thy word”; (Genesis 23:13) “Oh that thou wouldst (לו) only hear me”; (Joshua 7:7) “Would that (לו) we had been content”; (Numbers 14:2) “Would that (לו) we had died”. ,There are examples of לו used in the sense of “if” and “אולי” as, (Deuteronomy 32:29) “If (לו) they were wise [they would understand this]”; (Isaiah 48:18) “If (לוא) thou wouldst hearken to my commandments, [then would thy peace be as a river]”; (2 Samuel 18:12) “If (לו) I would receive [a thousand pieces of silver] in my hands, [yet would I not put forth my hand etc.]”. There is an example of לו used in the sense of “perhaps”, — in our verse — “Perhaps he will hate us”, but there is no other example of its usage in this sense in Scripture. Here it corresponds in sense with the word אולי, “perhaps”, as for example in (Genesis 24:5) “אולי the woman will not be willing to follow me” which means “perhaps she will not etc.” As a matter of fact אולי has all the meanings of לו, for there are examples of אולי denoting a petition as for instance (2 Samuel 16:12) “Perhaps (אולי) the Lord will look upon mine eye”, (where the context shows that this involves a kind of petition that God should do this); (Joshua 14:12) “Perhaps (אולי) the Lord will be with me [and I shall drive them out]”, (involving also a petition that God should do this), where אולי has a similar meaning to לו in (Genesis 30:34) “Would (לו) it might be according to thy word”. Then again the word אולי has the meaning of “if”; for example, (Genesis 18:24) “Perhaps (אולי) there are fifty righteous [wilt Thou destroy etc.]” (which is equivalent to “if there are fifty… wilt thou destroy?”.)
