There's good news and bad news: Abraham, Sarah, and the three messengers

(1) The LORD 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 men standing near him. As soon as he saw them, 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.

(9) They said to him, “Where is your wife Sarah?” And he replied, “There, in the tent.” (10) Then one said, “I will return to you next year, and your wife Sarah shall have a son!” Sarah was listening at the entrance of the tent, which was behind him. (11) Now Abraham and Sarah were old, advanced in years; Sarah had stopped having the periods of women. (12) And Sarah laughed to herself, saying, “Now that I am withered, am I to have enjoyment—with my husband so old?” (13) Then the LORD said to Abraham, “Why did Sarah laugh, saying, ‘Shall I in truth bear a child, old as I am?’ (14) Is anything too wondrous for the LORD? I will return to you at the same season next year, and Sarah shall have a son.” (15) Sarah lied, saying, “I did not laugh,” for she was frightened. But He replied, “You did laugh.”

(16) The men set out from there and looked down toward Sodom, Abraham walking with them to see them off. (17) Now the LORD 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 the LORD by doing what is just and right, in order that the LORD may bring about for Abraham what He has promised him.” (20) Then the LORD 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.” (22) The men went on from there to Sodom, while Abraham remained standing before the LORD.

(23) Abraham came forward and said, “Will You sweep away the innocent along with the guilty? (24) What if there should be fifty innocent within the city; will You then wipe out the place and not forgive it for the sake of the innocent fifty who are in it? (25) Far be it from You to do such a thing, to bring death upon the innocent as well as the guilty, so that innocent and guilty fare alike. Far be it from You! Shall not the Judge of all the earth deal justly?” (26) And the LORD answered, “If I find within the city of Sodom fifty innocent ones, I will forgive the whole place for their sake.” (27) Abraham spoke up, saying, “Here I venture to speak to my Lord, I who am but dust and ashes: (28) What if the fifty innocent should lack five? Will You destroy the whole city for want of the five?” And He answered, “I will not destroy if I find forty-five there.” (29) But he spoke to Him again, and said, “What if forty should be found there?” And He answered, “I will not do it, for the sake of the forty.” (30) And he said, “Let not my Lord be angry if I go on: What if thirty should be found there?” And He answered, “I will not do it if I find thirty there.” (31) And he said, “I venture again to speak to my Lord: What if twenty should be found there?” And He answered, “I will not destroy, for the sake of the twenty.” (32) And he said, “Let not my Lord be angry if I speak but this last time: What if ten should be found there?” And He answered, “I will not destroy, for the sake of the ten.” (33) When the LORD had finished speaking to Abraham, He departed; and Abraham returned to his place.

The Gemara continues analyzing the same passage. It is written: “And I will fetch a morsel of bread, and satisfy your heart” (Genesis 18:5), and it is written: “And Abraham ran to the herd, and fetched a calf tender and good” (Genesis 18:7). Rabbi Elazar said: From here we learn that the righteous say little and do much, whereas the wicked say much and do not do even a little.

באלוני ממרא BY THE TEREBINTHS OF MAMRÉ — It was he (Mamre) who advised him (Abraham) regarding the circumcision and therefore He revealed himself to him in his (Mamre’s) territory (Genesis Rabbah 42:8).

וירא AND HE SAW — What does the repetition of this word וירא imply? The first time it has its ordinary meaning (“he looked”), the second that of understanding: he saw that they were standing in one spot, and so understood that they had no desire to cause him any trouble. Although they knew that he would go to meet them they nevertheless remained where they were out of respect to him and to show him that they wished to spare him trouble; he, therefore, took the initiative and ran towards them. In the Treatise Bava Metzia 86b we have the following: It is written, “they were standing by him” and it is also written “He ran towards them” — how can these apparently contradictory statements be reconciled? But the explanation is, that at first they stood by him and when they perceived that he was loosening and re-binding his bandages, they retired from him; he therefore immediately ran towards them.

And He appeared to him: The language of Rashi - to visit the sick man. Rabbi Hama the son of Hanina said, "It was the third day after his circumcision and the Holy One, blessed be He, came and inquired [about the state of his health]." "And behold, three men came" - the angels that came to him with the appearance of men were three - one to announce to Sarah [the birth of a son], one to cure Abraham and one to overthrow Sedom - and Raphael, who healed Avraham, went from them to save Lot, as this is not two assignments, because it was a different place and he was commanded afterwards or [because] they are both about saving (and therefore really one). "And they ate" - they appeared to be eating. And in the book, Guide for the Perplexed 2:4, it is said that the section is [presented in the style of] the general [followed] by the details: the verse first states that God appeared to him in prophetic visions and [then] how this prophetic vision was - that he lifted up his eyes in a vision and behold, three men were standing upon him. "And he said, 'If I have found favor in your eyes'" - this is the recounting of what he said in a prophetic vision to one of them, to the greatest one of them. And if in the vision the only thing that appeared was just three men eating meat, how could it state, "And God appeared to him?" As behold, God did not appear to him, not in a vision and not in thought. And it is not found like this in all of the prophecies. And behold, according to his words, Sarah did not knead cakes and Avraham did not fix the young cow, and also Sarah did not laugh. [Rather,] everything was a vision. And, if so, this dream came 'with much detail' like the false dreams, as what is the point in showing him all of this? And [the Guide there] also said about the matter of "and a man wrestled with him" (Genesis 32:25), that it was all a prophetic vision. And [if so,] I don't know why he limped on his thigh when he woke up, and why he said (Genesis 32:31), "For I have seen God face to face and He saved my soul"; as the prophets did not fear that they would die because of prophetic visions. And he already saw a greater and more glorious vision than this - as he even saw the glorious God many times in a prophetic vision (see further Genesis 28:13 and 31:3). And behold, according to his opinion, this would require [us] to say this in the matter of Lot - that the angels did not come to his house and he did not bake for them matsot and [that] they ate, but [rather] the whole thing was a vision. [But] how were the evil and sinful people of Sedom prophets? As [otherwise], who told them that people came to his house? And if it was all prophetic visions of Lot, [then] "and the angels pressed, etc. 'Get up, take your wife'" (Genesis 19:15), "and he said, 'escape for your life'"(Genesis 19:17), and "Behold, I have lifted up your face" (Genesis 19:21) and the whole section would be a vision. And Lot would have stayed in Sedom and [Rambam] would think that the acts would have been done on their own, and the statements in each and every thing were a vision. And these things contradict Scripture - it is forbidden to hear them, and even to believe them. And in truth, in all places in Scripture where the seeing of an angel or the word of an angel is mentioned, it is in a vision or in a dream - as the senses cannot perceive angels - but not prophetic visions. As one who [merely] perceives to see an angel or his word is not a prophet; as the matter is not as the teacher defines (Guide for the Perplexed 2:34, Mishneh Torah, Foundations of the Torah 7:6), that the prophecy of every prophet besides Moshe, our teacher, was through an angel. And they have already said about Daniel (Megilah 3a), "They are better than he, as they were prophets and he was not a prophet." And so his book was not written together with the books of the Prophets, because his matter was with [the angel,] Gavriel - even though he appeared to him and spoke to him in a waking state, as it is stated in the vision of the Second Temple (Daniel 9:21), "And I was still speaking in prayer and the man, Gavriel." And so [too], the vision of the final salvation was in a waking state, in his walking with his fellows "alongside the river" (Daniel 10:4). And [likewise] Hagar the Egyptian was not in the category of prophetesses, but it is also clear that her matter was not that of a bat kol (a sub-prophetic heavenly voice), as the teacher said (Guide for the Perplexed 2:34). And the verse distinguished between the prophecy of Moshe, our teacher, and the prophecy of the patriarchs, as it states (Exodus 6:3), "And I appeared to Avraham, to Yitschak and to Yaakov as God Almighty" - and this is one of the holy names of the Creator; it is not the appellation of an angel. And our rabbis also learned about the difference between them and said (Vayikra Rabbah 12:11), "What is [the difference] between Moshe and all the prophets? Our rabbis said, 'All of the prophets saw through a lens that is not polished, such that it is written (Hoshea 12:11), "and I increased the vision and through the prophets I appeared"; And Moshe saw through a polished lens, such that it is written (Numbers 12:8), "the picture of God does he see,"'" as it is explained in Vayikra Rabbah and in other places (Yevamot 49b). And in no place did they [attribute] their prophecies to an angel. And do not be astonished because it is written (I Kings 13:18), "I am also a prophet like you and an angel spoke to me with the word of the Lord, saying"; as its explanation is "I am also a prophet like you, and I know that the angel who spoke to me was with the word of the Lord." And this is one of the levels of the levels of prophecy, as the man of God [also] said (I Kings 13:9), "As so did He command me with the word of the Lord" and (I Kings 13:17) "as the word was to me in the word of the Lord." And our rabbis already said (Bemidbar Rabbah 20:3) about the matter of Bilaam who said, "And now if it is bad in your eyes" (Numbers 22:34), "I did not go until the Holy One, blessed be He, said to me, 'get up, go with them' (Numbers 22:20), and you say that I should go back? Thus is His practice - did He not say thus to Avraham, to sacrifice his son, and afterwards, 'and the angel of the Lord called to Avraham a second time [...] And he said, "do not send your hand upon the youth"' (Genesis 22:11-12). He is accustomed to saying a thing and that an angel take it back, etc." Behold, the sages are bringing [it] up to say that the first prophecy that mentions God is not equal to the second prophecy, about which it says that it is through an angel. But rather, this is the way of prophets, that He will command [them] with a prophecy, and revoke the commandment through an angel, since the prophet knows that [the latter] is the word of the Lord. And at the beginning of Vayikra Rabbah 1:9, they said, "'And He called to Moshe' (Leviticus 1:1), not like Avraham. With Avraham it is written (Genesis 22:15), 'And the angel of the Lord called to Avraham a second time from the Heavens' - the angel calls and the [Divine] speech speaks. However, here the Holy One, blessed be He, says, 'I am the caller and I am the speaker'"; which is to say that Avraham did not perceive the prophecy until he prepared his soul first with the perception of the angel, and he [then] went up from that level to the level of prophetic speech. But Moshe was prepared for prophecy at all times and in all places. The sages saw fit to inform us [here] that the seeing of the angel is not prophecy and that those that see angels and speak with them are not in the category of prophets, as I mentioned with Daniel. [Rather], it is a vision called uncovering of the eyes, as in "And the Lord uncovered the eyes of Bilaam and he saw the angel of the Lord" (Numbers 22:31), and "And Elisha prayed and said, 'O Lord, uncover his eyes and he shall see" (II Kings 6:17). But in a place where it mentions the angels with the name, 'people,' like the matter of this section and in the section with Lot, and so [too], "and a man wrestled with him" (Genesis 32:25), and so [too], "And a man found him" (Genesis 37:15) - according to the opinion of our rabbis (Midrash Tanchuma, Vayeshev 2), it is the glory that is created with the angels - that is called by those who know, 'a garment - that is perceived by eyes of flesh, by those of pure souls; like the pious ones and the students of the prophets. And I cannot explain [it]. And about the place where you find in it seeing of the Lord and the word of the angel, or seeing of the angel and the word of the Lord, as it is written in the words of Moshe at the beginning of his prophecy (Exodus 3:2-4) and in the words of Zechariah 3:1-2, I will still reveal the words of the living God with hints (see Ramban on Exodus 3:2). And about "and they ate," the sages said (Bereshit Rabbah 48:14), "it is removed, one at a time." And the matter of removal you will understand from the matter of Manoach (Judges 13:19), if you merit it. And behold, the explanation of this section is that after it stated (Genesis 17:26), "On that very day was Avraham circumcised," it stated that God appeared to him in his being sick from his circumcision, sitting and cooling off at the opening of his tent because of the heat of the day, which weakened him; and it mentioned this to inform that he was not intending prophecy - he did not fall on his face and he did not pray - and nonetheless, the vision came to him.

מפתח האהל, he began running from the entrance of his tent. When a person is observed to perform any task with speed, with keenness, this reflects that he considers what he is about to do as important. We have another example of such conduct in Exodus 34,8 וימהר משה ויקוד ארצה וישתחו, “Moses hastened to bow down and to prostrate himself.”

Rav Yehuda says that Rav says: Every action that Abraham performed himself for the ministering angels, the Holy One, Blessed be He, performed Himself for Abraham’s descendants. And every action that Abraham performed through a messenger, the Holy One, Blessed be He, likewise performed for his descendants through a messenger. The Gemara elaborates: With regard to Abraham, the verse states: “And Abraham ran to the herd” (Genesis 18:7), bringing the meat himself, and in reference to God’s actions for Abraham’s descendants the verse states: “And there went forth a wind from the Lord, and brought across quails from the sea” (Numbers 11:31), that God brought meat to them. In reference to Abraham, the verse states: “And he took curd and milk” (Genesis 18:8), and God says to the Jewish people: “Behold, I will cause to rain bread from heaven for you” (Exodus 16:4), which shows that God gave food to the Jewish people. With regard to Abraham, the verse states: “And he stood by them under the tree, and they ate” (Genesis 18:8), and in reference to God, the verse states: “Behold, I will stand before you there upon the rock in Horeb; and you shall strike the rock, and there shall come water out of it” (Exodus 17:6). In the case of Abraham it is written: “And Abraham went with them to bring them on the way” (Genesis 18:16), and the verse states: “And the Lord went before them by day” (Exodus 13:21). By contrast, Abraham performed certain actions through an agent. He said: “Let now a little water be fetched” (Genesis 18:4), and correspondingly the verse states in reference to Moses, God’s messenger: “And you shall strike the rock, and there shall come water out of it, that the people may drink” (Exodus 17:6).
