מדרש אויף בראשית 14:16

“The adversary extended his hand over all her delights; for she saw the nations entering her Sanctuary, whom You had commanded that they should not enter Your assembly” (Lamentations 1:10).
“The adversary extended his hand.” You find that when the enemies entered the Temple, Amonites and Moavites entered with them. Everyone was running to plunder silver and gold, and the Amonites and Moavites were running to plunder the Torah, in order to remove “An Amonite and Moavite shall not enter the assembly of the Lord” (Deuteronomy 23:4). Rabbi Yehuda ben Rabbi Simon [said] in the name of Rabbi Levi ben Perata: This is analogous to a conflagration that was ignited in a king’s palace. Everyone was running to plunder the silver and the gold while a slave ran to plunder his writ of servitude. So too, when the enemies entered the Temple, Amonites and Moavites entered with them. Everyone was running to plunder silver and gold, and the Amonites and Moavites were running to plunder the Torah, in order to remove “An Amonite and Moavite shall not enter the assembly of the Lord.”
Abraham bestowed four good things upon Lot. That is what is written: “Abram went, as the Lord had spoken to him, and Lot went with him” (Genesis 12:4). And it says: “Lot, too, who was going with Abram [had sheep, cattle and tents]” (Genesis 13:5). And it says: “He returned all the property, [and also his brother Lot and his property he returned]” (Genesis 14:16). And it says: “It was when God destroyed the cities of the plain [God remembered Abraham, and He sent Lot from the midst of the upheaval]” (Genesis 19:29). Correspondingly, they should have repaid them with goodness;¹⁴³Lot’s descendants, the nations of Amon and Moav, should have been kind to Abraham’s descendants. however, they performed acts of wickedness. That is what is written: “He sent messengers to Bilam…now, please go and curse for me…. The elders of Moav and the elders of Midian went…” (Numbers 22:5–7). “He gathered to him the children of Amon and Amalek, [and he went and smote Israel]” (Judges 3:13).¹⁴⁴The verse is stated regarding Eglon, king of Moav. “It was thereafter, the children of Moav, and the children of Amon, and with them some Amonites, came against Yehoshafat” (II Chronicles 20:1). And this: “The adversary extended his hand...”
Correspondingly, their sins are written in four places. “An Amonite and Moavite [shall not enter the assembly of the Lord]…because they did not greet you with bread and with water…” (Deuteronomy 23:4–5). “My people, remember now what Balak king of Moav devised…” (Micah 6:5). “Because they did not greet the children of Israel with bread and with water, and hired Bilam against them, to curse them” (Nehemiah 13:2). “He sent and summoned Bilam son of Beor to curse you” (Joshua 24:9).
Correspondingly, four prophets stood and sealed their sentence, and they were: Isaiah, Jeremiah, Ezekiel, and Zephaniah. Isaiah said: “A prophecy of Moav: For on the night that Ar of Moav is plundered, it is ruined; for on the night that Kir of Moav is plundered, it is ruined” (Isaiah 15:1). Jeremiah said: “Behold, days are coming, the utterance of the Lord, and I will sound to Raba of the children of Amon an alarm of war, and it will become a mound of desolation, and its environs will be burned in fire, and Israel will inherit its inheritors, said the Lord” (Jeremiah 49:2). Ezekiel said: “To the children of the east, against the children of Amon, and I will give it as a heritage, so that the children of Amon will not be remembered among the nations. I will administer punishments to Moav, and they will know that I am the Lord” (Ezekiel 25:10–11). Zephaniah said: “Therefore, as I live, the utterance of the Lord of hosts, God of Israel, Moav will be like Sodom and the children of Amon like Gomorrah, a rustling thornbush, a salt mine, a desolate wasteland forever. The remnant of My people will plunder them and the rest of My nation will inherit them” (Zephaniah 2:9).

[3] Alternative interpretation: "After these events, what is written above the matter? 'And Abraham heard that his brother was taken captive'." (Genesis 14:14). And although his brother was Lot, after all the strife that they had, as it says "And there was strife between the herdsmen of Abram's cattle and the herdsmen of Lot's cattle" (Genesis 13:7), Abram still referred to Lot as his brother, as it says "For we are brothers" (Genesis 13:8). "And he armed his trained servants" (Genesis 14:14). From here we learn that Abram took silver, gold, and jewelry and adorned them, and said to them, "We are going to war to save Lot. Do not focus on wealth. If you are going for the sake of silver and gold, there is plenty before you." As it says, "And he armed his trained servants." And "armed" can only mean adorned with silver and gold, as it says "Her wings are covered with silver, and her pinions with yellow gold" (Psalms 68:14). Alternatively, "armed" means empty-handed, as it is written in the Torah, "Who is the man that is fearful and soft-heated?" (Deuteronomy 20:8), Abraham acted similarly. He said to his troops, "You are going out to war, but anyone who has sins in his hand and is afraid of his deeds should not go out with us." When all those men heard this, anyone who knew in his heart that he had sinned did not go out with Abraham, and they all turned back except for Eliezer who was righteous. Then, God said to Abraham, "He will go with you, and I will give him the strength of 318 men, so it will be as if all of them went out with you." Similarly, Eliezer's strength was equivalent to 318 men. And Abraham pursued [the kings] as far as Dan (Genesis 14:14). Why did he pursue them all the way to Dan? Our sages said that there are two things that are punished, those who plant a tree in the Sabbatical year and those who sell the produce of the Sabbatical year. Similarly, Abraham punished them before and after the prohibition [against such actions] came into effect. And how did he do so before [the prohibition was enacted]? Until now, when Jeroboam, the son of Nebat, would establish an idol in Dan, as it is said, "And he put one in Beth-El and the other he placed in Dan" (1 Kings 12:29). Abraham had already arrived at that place and did not pursue them any further, as it is written, "And he pursued them as far as Dan, and he recovered all the goods" (Genesis 14:15).. What did he see in pursuing them to Dan? Our sages said two things strike those who are before and after, as in the case of the "sabbatical year" where one who plants before it and after it is liable. Similarly, Abraham pursued them before and after, but how did he pursue them until now when Jeroboam son of Nebat set up a sanctuary in Dan, as it says, "And he placed the one in Bethel [and the other he put in Dan]" (1 Kings 12:29)? Abraham had already reached that place and did not pursue them anymore, as it says, "And he pursued them to Dan and he divided himself against them by night" (Genesis 14:15). The Holy One, blessed be He, did this for Abraham, as it says, "And it came to pass that at midnight the Lord smote" (Exodus 12:29), "And he brought back all the goods" (Genesis 14:16), "Then the king of Sodom went out to meet him" (Genesis 14:17). When the king of Sodom saw Abraham coming to pursue him, he was playing with him, as it says, "All those who see me will mock me" (Psalms 22:8). This was the king who went out to pursue sixteen kings and their armies. When he returned safely, he said, "Let them pass in peace" (Isaiah 43:3). "Then the king of Sodom went out to meet him" (Genesis 14:17), and said to him, "Give me the persons" (Genesis 14:21). Abraham immediately swore to him, as it says, "I have lifted my hand" (Genesis 14:22), and lifting one's hand is an oath, as it says, "He raised his right hand and his left hand to heaven [and swore by the living God]" (Daniel 12:7). "If from a thread" (Genesis 14:23), why did the Holy One, blessed be He, promise to tithe me, as it says, "And I will bless those who bless you" (Genesis 12:3)? "And I will curse him who curses you" (Genesis 12:3). I am poorer than you. You should say, "I enriched you." "If from a thread" (Genesis 14:23). The Holy One, blessed be He, said to him, "You said, 'If from a thread.' I will give your children a thread of righteousness that will encompass them, just as the sages have explained." "I give your children the commandment of tzitzit which is made of thread, as it says 'they shall make for themselves fringes' (Numbers 15:38). You said until shoelace, I give your children the commandment of shoe removal, as it says 'he shall remove his shoe' (Deuteronomy 25:9). Additionally, I give your children the merit of the Passover commandment, as it says 'you shall eat it with your loins girded, your sandals on your feet' (Exodus 12:11). If you said from thread, I praise your children with the thread, as it says 'your hair is like a flock of goats' (Song of Songs 4:2). Moreover, in the merit of this, I punish their enemies, as it says 'over Edom I cast my shoe' (Psalms 60:9). If you said until shoelace, I praise your children with their footwear, as it says 'how beautiful are your steps in sandals' (Song of Songs 7:1). You have rejected the reward of flesh and blood, see the reward that is prepared for you, as it says 'your reward is very great' (Genesis 15:1)."

And you see horse and chariot (Deuteronomy 20:1): And it is stated (Exodus 15:19), "For when the horse of Pharaoh." And why did it not state, "horses and riders?" Rather [it is] because in front of the Holy One, blessed be He, they are only considered like one horse. "A people more numerous than you." The Holy One, blessed be He, said, "They are numerous in front of you. But in front of Me, they are only only considered like one man." And from where [do we know this]? As so did the Holy One, blessed be He, say to Gidon (Judges 6:16), "and you shall smite Midian like one man." And from where [do we know] that they are numerous? As it is stated (Isaiah 17:12), "Ah, the roar of many peoples that roar as roars the sea." And for each one of you, a hundred [to] five, but you are victorious, as it is stated (Leviticus 26:8), "And five of you shall give chase to a hundred." Therefore it is written, "a people more numerous than you." "Do not be afraid of them." Your forefathers were not afraid of them and they were victorious. What is written about our father, Avraham? "At night, he and his servants deployed against them and defeated them" (Genesis 14:16). And he was not afraid of them, as I told him (Genesis 15:1), "Fear not, Avram, I am a shield to you; your reward shall be very great." And I made him a shield, as it is stated, "I am a shield to you." And in the same way that I did [this] for him, so [too] will I do it for you. As it is stated (Isaiah 14:24), "As I have designed, so shall it happen; what I have planned, that shall come to pass." What is [the meaning of] "As I have designed?" As I have done for Avraham, so shall I do for you.
