Le Deutéronome 2:28 Midrash : Bamidbar Rabbah, Midrash Tanchuma & Midrash Tanchuma Buber

“Siḥon did not allow Israel to pass within his border, and Siḥon gathered his entire people and came out toward Israel to the wilderness, and he came to Yahatz; and he fought against Israel” (Numbers 21:23).
“Please, let us pass through your land” (Numbers 20:17) – just as he sent to the king of Edom that he would not harm him, so he sent to this one: “You will sell me food for silver […and water for silver]” (Deuteronomy 2:28) – typically, water is given for free, but we will pay its price. “We will go on the king’s way […until we pass your border]” (Numbers 20:17). Elsewhere it is written: “Until I will cross [the Jordan]” (Deuteronomy 2:29). I will tell you a parable, to what is the matter comparable? It is to a watchman who took his wages to guard a vine or a fig tree. One came and said to him: ‘Move from here, as I am harvesting the vineyard.’ He said to him: ‘I am sitting here and guarding only against you, and you are coming to harvest it?’ So, Siḥon took his payment from all the kings of the land of Canaan, and they would pay him taxes, as he would crown them as kings. He and Og were equal to them all, as it is stated: “Siḥon king of the Emorites, Og king of Bashan, and all the kingdoms of Canaan” (Psalms 135:11). Israel said: ‘Let us pass through your land to conquer the kingdom.’ He said to them: ‘I am sitting here only to guard them from you’ – “Siḥon did not allow Israel to pass within his border.”
“Siḥon gathered” – the Holy One blessed be He acted with forethought to deliver him into their hands with no trouble. It is written: “Siḥon king of the Emorites, who resides in Ḥeshbon” (Deuteronomy 1:4). Were Ḥeshbon filled with gnats, no person would be able to conquer it; were Siḥon in a valley, no person could gain control over him; and it goes without saying when he is a mighty warrior and located in a fortified city. “Who resides in Ḥeshbon” – had he been residing in his cities, he and his multitudes, Israel would have exhausted themselves in the attempt to conquer each and every city. Instead, the Holy One blessed be He assembled them [the Emorites] before them to deliver them into their hands with no trouble. Likewise it says: “See, I have begun delivering before you” (Deuteronomy 2:31) – they killed all his mighty warriors who had emerged to meet them, and returned against the women and children without exertion. That is why it is written: “Siḥon gathered.” “Israel took all these cities” (Numbers 21:25).

(Numb. 21:21:) “Then Israel sent messengers.” All the words of Torah are necessary to each other, for what one covers over the other opens up.¹⁴⁶Numb. R. 19:28. It is stated here (in Numb. 21:21), “Then Israel sent messengers,” while in another place [Scripture] ascribes the sending to Moses. [Thus] it is stated (in Deut. 2:26), “Then I sent messengers from the Desert of Kedemoth [unto King Sihon of Heshbon with words of peace].” In another place [it is stated (in Numb. 20:14)], “Moses sent from Kadesh messengers to the king of Edom.” These verses require one another, as Moses is Israel and Israel is Moses. [This comes] to teach you that the head of a generation is surely equivalent to the whole generation. (Numb. 20:17:) “Please let us pass through your land.”¹⁴⁷As Buber suggests in note 370, the citation is probably a misreading for Numb. 20:22: LET ME PASS THROUGH YOUR LAND. This alternate reading better fits the context and also agrees with the parallel in Numb. R. 19:29. As he had sent to inform the king of Edom that he would do no damage, so did he send to this one.¹⁴⁸The bracketed words come from the parallel in Numb. 19:19 and are necessary for the sense of the argument. (Deut. 2:28), “You shall sell me food for money, and water with money….” It is customary for water to be given gratis, but I am giving payment for it. (Numb. 21:22) “We will go by the king's highway [until we have passed through your territory].” But in another place it is written (in Deut. 2:29), “until I have crossed the Jordan.” The matter is comparable to one guarding a vine or fig tree. When someone comes and says, “Let me pass through here, so that I may gather grapes from the vineyard,” he says to him, “It is only because of you that I am sitting on guard, and you would come to gather [the grapes]?” So it was with Sihon. He received wages from all the kings of Canaan; and they would bring taxes up to him, for he would crown them. Moreover he and Og were considered the equivalent of them all, since it is stated (in Ps. 136:19-20), “Sihon, king of the Amorites…; And Og, king of Bashan.” Israel said to [Sihon], “Let us pass through your land¹⁴⁹“Let us pass through your land” is similar but not quite equal to either Numb. 20:17 or Numb. 21:22. to conquer the kings.” He said to them, “I am sitting here to guard them from you.” (Numb. 21:23:) “So Sihon did not allow Israel to cross on his territory; instead Sihon gathered all his people together and went out against Israel.” The Holy One, blessed be He, only did this to deliver him into their hand without trouble. As it is written (in Numb. 21:34 = Deut. 3:2), “to Sihon, king of the Amorites who dwelt in Heshbon (i.e., with calculation).”¹⁵⁰The stress on the Holy One acting with fore-thought was suggested by the words, IN HESHBON, which can also be translated WITH CALCULATION. If Heshbon had been full of mosquitos, no mortal could have conquered it; and if Sihon had been in a valley, no mortal could have overpowered him. And it goes without saying [that it could not be conquered], since he was a warrior and dwelt in a fortified city. [Ergo,] (in Numb. 21:34 = Deut. 3:2), “Sihon, king of the Amorites who dwelt in Heshbon.” If he and his troops¹⁵¹Gk.: ochloi. had dwelt [scattered about] in his towns, Israel would have worn themselves out to prevail against him and conquer each and every town. Instead the Holy One, blessed be He, gathered them together so as to deliver them into their hand without trouble. And so it said (in Deut. 2:31), “See I have begun to give Sihon [and his land] over to you.” They killed all his warriors who had come out against them. Then they returned for the women and infants without exertion. It is therefore written (in Numb. 21:23), “instead Sihon gathered all his people together.”

(Numb. 20:17:) PLEASE LET US PASS THROUGH YOUR LAND. <WE WILL NOT PASS THROUGH FIELD OR VINEYARD, > NOR SHALL WE DRINK WATER FROM A WELL. Should it have said: "Water from cisterns?" <By this use of the singular, A WELL>, Torah has taught you proper conduct, <i.e.,> that when one who goes to a land which is not one's own, [though he has at hand his necessities,] he should not drink from what he has on hand. Rather he should put aside what he has, and buy from the shopkeeper in order to benefit him. So also Moses said to <the king of Edom>: <We have> a well with us,¹⁵²On the tradition of Israel’s portable well for supplying them with water during their desert wanderings, see above, Lev. 7:7; Numb. 1:2; below, Numb. 6:47-50; Tanh., Numb. 1:2; Numb. R. 1:2; TSuk. 3:11; Targum Pseudo-Jonathan, Numb. 21:16-18; Frag. Jerusalem Targum, Numb. 21:17-18; Tanh., Lev. 7:7; Lev. R. 25:5; 27:6; see also Avot 5:6; Mekhilta deRabbi Ishmael, Wayassa‘ 6, on Exod. 16:32; Shab. 35a; Pes. 54a; Targum Pseudo-Jonathan, Numb. 22:28; in addition, see TSot. 11:8 (10); Ta‘an. 9a; BM 86b; Cant. R. 4:14:1; Seder ‘Olam Rabbah, 10; cf. I Corinthians 10:4. and we eat our own manna; <but> do not say that we are a bother to you. You will make a profit for yourselves. So also did Moses say (to king Sihon of Heshbon in Deut. 2:28): YOU SHALL SELL ME FOOD FOR MONEY.
