Génesis 18:5 Midrash: Kohelet Rabbah, Mekhilta DeRabbi Yishmael, Midrash Tanchuma & Midrash Tanchuma Buber

“Cast your bread on the surface of the water, for after many days you will find it (Ecclesiastes 11:1).
“Cast your bread on the surface of the water” – Rabbi Beivai said: If you sought to perform charity, perform it with those who toil in Torah study, as water stated here is nothing other than words of Torah, as it is stated: “Anyone thirsty, go to water” (Isaiah 55:1).¹This verse is interpreted as using the term water to refer to Torah, as implied by the continuation: “Incline your ear and come to Me, hear and your soul shall live” (Isaiah 55:3). Rabbi Akiva said: When I was coming by sea, I saw a ship that sank in the sea, and I was very sorry about a certain Torah scholar who was on it and [must have] drowned. When I arrived at the province of Kapotkeya, I saw him, that he was sitting before me and asking questions. I said to him: ‘My son, how did you ascend from the sea?’ He said: ‘Rabbi, due to your prayer, each wave cast me to another, and another to another until they caused me to reach dry land.’ I said to him: ‘My son, what deeds do you have to your credit?’ He said: ‘When I boarded the ship, a certain unfortunate man encountered me. He said to me: Perform charity for me, and I gave him a loaf. He said to me: Just as you gave me my life with your gift, so may your life be given to you.’ I read in his regard: “Cast your bread on the surface of the water.”
There was an incident involving a certain large ship that set sail in the Mediterranean Sea. The wind took hold of it and brought it to a place where there was no flowing water.²The water currents in that location swirled in such a way that the ship was unable to progress. When they realized that they were in serious trouble, they said: Let us share our supplies. If we die, all of us will die. If we live, all of us will live. The Omnipresent enlightened their eyes and they took a goat, roasted it, and suspended it on the west side of the ship. A great beast came after its aroma and began dragging [the ship] until it cast it into flowing water and they traveled on. When they arrived and entered Rome, they recounted the incident to Rabbi Eliezer and Rabbi Yehoshua. They read in their regard: “Cast your bread on the surface of the water.”
Bar Kappara was digging³Some commentaries contend that the text should read: Bar Kappara was strolling (Matnot Kehuna; Etz Yosef). on the coast at Caesarea. He saw a ship that had sunk in the sea and a governor ascending from it unclothed. When [bar Kappara] saw him, he approached him, inquired after his welfare, and gave him two sela. What [else] did he do? He took him into his house, fed him, gave him to drink, and gave him an additional three sela. He said to him: ‘A prominent man like you will [need to] spend an additional three sela.’ Sometime later, Jews were incarcerated in Safefasa. They said: ‘Who will go and appease [the authorities] on our behalf?’ They said to each other: ‘Bar Kappara, as he is esteemed by the government.’ He said to them: ‘You know that this kingdom does nothing for free.’ They said to him: ‘There are five hundred dinars here; take them and appease them on our behalf.’ He took five hundred dinars and ascended to the governmental authorities. When the governor saw him, [the governor] stood on his feet and inquired after his welfare. [The governor] said to him: ‘Why did the Rabbi trouble himself to come here?’ [Bar Kappara] said to him: ‘I am requesting from you that you have mercy on these Jews.’ [The governor] said to him: ‘You know that this kingdom does nothing for free.’ [Bar Kappara] said to him: ‘I have with me five hundred dinars. Take them and be appeased in our regard.’ [The governor] said to him: ‘Let these dinars be payment to you for the five sela that you gave me, and [the members of] your nation will be freed in exchange for the food and the drink that you fed me and gave me to drink in your house, and go you in peace, with great honor.’ They read in his regard: “Cast your bread on the surface of the water.”
Rabbi Elazar ben Shamua was strolling on the coast of the Mediterranean Sea. He saw a ship that was being tossed in the sea, and in an instant, it sank along with everything that was on it. He saw one man who was sitting on one of the planks of the ship. [His plank was tossed] from one wave to another; he ascended to dry land when he was naked, and he hid on the seacoast. It was the season when Jews ascend to Jerusalem for the pilgrimage festival. He said to them: ‘I am from the descendants of Esau your brother. Give me some minimal garments, and I will cover my nakedness, as the sea stripped me bare and I was left with nothing.’ They said to him: ‘May your entire nation be stripped bare in this manner.’ He lifted his eyes and saw Rabbi Elazar ben Shamua strolling among them. He said: ‘I see that you are an elderly and respected man in your nation, and you are wise in the ways of the dignity of people. Perform charity for me and give me a covering, for the sea stripped me bare.’ Rabbi Elazar ben Shamua had on him seven cloaks. He removed one and gave it to him. He led him to his house, fed him, gave him to drink, gave him two hundred dinars, transported him fourteen parasangs, and accorded him great honor until he brought him into his [own] house.
Sometime later, the evil emperor died, and they appointed a king in his place. He decreed on that province that all the men were to be executed and all the women to be plundered.⁴The new king was the man who had been saved from the ship. He issued the decree because the Jews of that province had treated him so poorly in his time of need. They said to Rabbi Elazar ben Shamua: ‘Go and appease them on our behalf.’ He said to them: ‘You know that this kingdom does nothing for free.’ They said to him: ‘There are four thousand dinars here; take them and appease them on our behalf.’ He took them and ascended, and stood at the gate of the royal palace.
He said to them: ‘Go and say to the king: One Jewish man is standing at the gate and he wishes to ask after the welfare of the king.’ [The king] said: ‘Bring him in.’ When the king saw him, he threw himself off his throne and fell on his face. He said: ‘What business does my master have here, and why did my master trouble himself to come here?’ [Rabbi Elazar ben Shamua] said: ‘It is so you will have mercy on that province and abrogate that decree.’ He said to him: ‘Is there any untruth written in the Torah?’ He said to him: ‘No.’ He said to him: ‘Is it not written in your Torah: “An Amonite and a Moavite shall not enter into the assembly of the Lord” (Deuteronomy 23:4)? Why? “Because they did not greet you with bread and with water” (Deuteronomy 23:5). And it is written: “Do not despise an Edomite, as he is your brother” (Deuteronomy 23:8). Am I not a descendant of Esau your brother?⁵The Edomites were descendants of Esau. This man was Roman, and the Sages identified Rome as descendants of the Edomites. But they did not treat me with kindness. One who violates the Torah incurs liability to be executed.’
Rabbi Elazar ben Shamua said to him: ‘Even though they have incurred liability toward you, pardon them and have mercy on them.’ He said to him: ‘You know that this kingdom does nothing for free.’ He said to him: ‘I have with me four thousand dinars. Take them and have mercy on them.’ He said to him: ‘Let these four thousand be given to you in exchange for the two hundred that you gave me, and the entire province will be pardoned because of you, in exchange for the food and the drink that you fed me and gave me to drink. Go into my treasury and take for yourself seven cloaks of garments in exchange for the cloak that you gave to me. Go in peace to your people, and I will pardon them because of you.’ They read in his regard: “Cast your bread on the surface of the water.”
There was an incident involving a certain man who each day would take one loaf and cast it into the Mediterranean Sea. One day he went and purchased a fish. He cut it open and found a jewel in it. They said to him: This is the man who received a return for his loaves. They read in his regard: “Cast your bread on the surface of the water.”
Rabbi Yitzḥak said: There was an incident involving a merchant who was walking along the way along with a certain soldier. As they were walking together they developed a fondness for one another. When they entered the city, [the merchant] brought him in with him, fed him, and gave him to drink. Sometime later this merchant was arrested for selling garments stained with blood.⁶The suspicion was that he had attacked travelers and stolen their garments. That soldier heard, and he came to him. He said to [the merchant]: ‘What are you doing here?’ [The merchant] recounted the incident to him. [The soldier] said to him: ‘When you go out to be tried, say to them that so-and-so knows to speak in my favor.’ When he went out to be tried, he said: ‘So-and-so knows to speak in my favor.’ They said to [the soldier]: ‘What favorable [considerations] do you know about this [individual]?’ He said to them: ‘The brother of someone who was killed owed me [money], but he did not have anything to give. He gave me his⁷The garments of his dead brother. garments, and I gave them to this one to sell them for me.’ They said: ‘A trustworthy one received it from a trustworthy one,’ and he was freed. They read in his regard: “Cast your bread on the surface of the water.”
Rabbi Elazar ben Rabbi Simai interpreted it regarding Abraham our patriarch. The Holy One blessed be He said to him: You said: “I will take a loaf of bread [and you shall sustain your heart]” (Genesis 18:5); by your life, I will repay your descendants in the wilderness, in the settlement, and in the future. In the wilderness, as it is stated: “Behold I will rain bread down to you from the heavens” (Exodus 16:4). In the settlement, as it is stated: “A land of wheat and barley” (Deuteronomy 8:8). And in the future as it is stated: “There will be an abundance of grain in the land” (Psalms 72:16).
You said: “And wash your feet” (Genesis 18:4); by your life, I will repay your descendants in the wilderness, in the settlement, and in the future. In the wilderness, as it is stated: “I will wash you in water…” (Ezekiel 16:9).⁸The verse means that God cleansed them of the impurity of Egypt. In the settlement, as it is stated: “Wash and be purified” (Isaiah 1:16). And in the future as it is stated: “When the Lord will have washed away the excrement of the daughters of Zion” (Isaiah 4:4).
You said: “Please let a little water be taken” (Genesis 18:4); by your life, I will repay your descendants in the wilderness, in the settlement, and in the future. In the wilderness, as it is stated: “Arise, well, [give voice for it]” (Numbers 21:17).⁹Israel recited this expression of praise and gratitude for the miraculous well that provided water for them in the wilderness. In the settlement, as it is stated: “A land of streams of water…” (Deuteronomy 8:7). And in the future as it is stated: “It will be on that day, the mountains will drip nectar and the hills will flow with milk; all the streams of Judah will flow with water…” (Joel 4:18).
You said: “Recline under the tree” (Genesis 18:4); by your life, I will repay your descendants in the wilderness, in the settlement, and in the future. In the wilderness, as it is stated: “He spread a cloud for a screen” (Psalms 105:39). In the settlement, as it is stated: “You shall dwell in booths seven days; every native in Israel shall dwell in booths” (Leviticus 23:42). And in the future as it is stated: “It will be a shelter for shade by day…” (Isaiah 4:6).

(Exodus, Ibid. 21) "And the L–rd went before them by day": We are hereby taught that as one metes it out to others, so is it meted out to him. Abraham accompanied the ministering angels, viz. (Genesis 18:16) "And Abraham went with them to escort them, and the L–rd accompanied his children in the desert for forty years, viz.: "And the L–rd went before them by day with a pillar of cloud." Of our father Abraham it is written (Genesis, Ibid. 5) "And I will take a piece of bread," and the Holy One Blessed be He brought down the manna for forty years, viz. (Exodus 16:4) "Behold, I shall rain down bread for you, etc." Of Abraham it is written (Genesis, Ibid.) "Let there be taken now a little water, etc.", and the Holy One Blessed be He raised for His children a well in the desert, viz. (Numbers 21:17) "Bring up, O well — sing to it." Of Abraham it is written (Genesis, Ibid. 7) "And to the herd Abraham ran," and the Holy One Blessed be He flew in quail for his children, as it is written (Numbers 11:31) "And a wind went forth from the land and flew in quail from the sea." Of Abraham it is written (Genesis, Ibid. 4) "And recline under the tree," and the Holy One Blessed be He spread out for his children seven clouds of glory," as it is written (Psalms 105:39) "He spread out a cloud for shelter and a fire to illumine the night." Of Abraham it is written (Genesis, Ibid. 8) "and he stood over them," and the Holy One Blessed be He defended his children in Egypt, that they not be smitten, viz. (Exodus 12:23) "and the L–rd will skip over the door, etc."

And the two angels came to Sodom … and he said: “Behold now, my lords, turn aside, I pray you, into your servant’s house, and tarry all night, and wash your feet” (Gen. 19:1–2). There is a proverb which says: Associate with a greasy man and you too will become greasy. Because Lot associated with Abraham he learned to welcome travelers. And they said: “Nay” (ibid.): From this episode our sages taught that one may refuse the request of one’s inferior but not of one’s superior. It is written concerning Abraham that he said: And I will fetch a morsel of bread, and stay ye your heart … and they said: “So do as thou hast said” (ibid. 18:5), but in reference to Lot it is written: And he urged them greatly; and they turned into his house … and they ate (ibid. 19:3).¹³The angel initially rejected Lot’s invitation to enter his home, but accepted Abraham’s invitation immediately. See Pesahim 86b. Surely, ministering angels do not partake of food. This was done only in order to teach us that proper behavior requires that no man should deviate from the custom of the land. You learn this lesson from Moses as well. It is written that after he ascended the mountain: And he was there with the Lord forty days and forty nights, and he did neither eat bread nor drink water (Exod. 34:28). If it was customary to eat and drink there, he would have done so. Therefore concerning the angels who came to visit Abraham, to destroy Sodom and to rescue Lot, it is written: He made them a feast and baked them unleavened bread, and they ate (Gen. 19:3).
