Midrash su Giudici 11:28

R. Samuel b. Nachmeni, in the name of R. Jonathan, said: Three men made an unreasonable demand (making their actions dependent on chance); two of them were answered desirably (Providence favored their ways), but one was answered according [to his unreasonableness]. They are: Eliezer, the servant of Abraham; Saul, the son of Kish; and Jephthah, of Gilead. Concerning Eliezer it is written (Gen. 24, 13) … and the daughters of the men of this city come out to draw water, etc. Now, such a maiden might have been blind or maimed, nevertheless he was answered desirably when Rebekah came [providentially] to him. Concerning Saul, the son of Kish, it is written (I Sam. 17, 25) And it shall be, that the man who killeth him, the king enrich him with great riches, and will give him his daughter, etc. It might have happened that a slave, or an illegitimate son, might accomplish the feat, nevertheless he was answered desirably; and David came [providentially] to him. Concerning Jephthah it is written (Jud. 11, 31) Then it shall be, that whatsoever cometh forth of the doors of my house … I will offer it up for a burnt-offering. An unclean animal might have come forth [which would not be a proper sacrifice] . He was therefore answered undesirably, for his own daughter came [providentially] to meet him. This is meant by the words of the prophet (Jer. 8, 22) Is there no mere balm in Gilead? Or, is no physician there? And further, it is written (Ib. 19, 5) which I had not commanded nor spoken, and which had not come into my mind; i.e., which I had not commanded refers to the son of Mesha, the King of Moab, as it is said (II Kings, 3, 27) Then he took his eldest son that should have reigned in his stand, and offered him for a burnt-offering upon the wall. And there came great wrath upon Israel; and they departed from him, and returned to their own land; nor spoken, refers to the daughter of Jephthah, the Gilodite; and which had not come into my mind, refers to Isaac, son of Abraham." R. Berachia said: "The congregation of Israel also made an unreasonable demand, but the Holy One, praised be He! answered it in a desirable manner, as it is written (Hos 6, 3) And let us know, eagerly strive to know the Lord; His going forth is sure as the morning; and He shall come unto us as the rain, as the latter rain that watereth the earth. The Holy One, praised be He! said: 'My daughter, thou askest a thing which is sometimes desirous and sometimes superfluous, nevertheless I shall be to thee as a thing which is needed all the time; as it is said (Ib. 14, 6) I will be as the dew unto Israel. Another time did the congregation of Israel make an unreasonable demand, saying: 'Sovereign of the universe! (Songs 8, 6) Set me as a seal upon thy heart, as a seal upon thy arm.' Whereupon the Lord said: 'Thou askest me to do a thing which sometimes can be observed and sometimes cannot; but I will set thee as a seal in such a place that you will always be observed'; as it is said (Is. 49, 16) Behold, upon the palms of my hands have I engraved thee."

“When King [Aḥashverosh] was sitting [keshevet hamelekh].” Rabbi Yitzḥak said: The nations of the world do not sit securely. They objected: Is it not written: “When King [Aḥashverosh] was sitting”? He said to them: Beshevet hamelekh [while the king was sitting] is not written here, rather, keshevet hamelekh [as if the king were sitting] – sitting that is not sitting. However, the sitting of Israel is sitting, as it is stated: “When Israel sat [beshevet] in Ḥeshbon and its environs” (Judges 11:26).

“When a camp goes out against your enemies, you shall beware of everything evil” (Devarim 23:10). There should be no levity among you so that you do not incur any liability. From whom should you learn? From Yiftach. What is written about him? “…and he was the son of a harlot…” (Shoftim 11:1) Rabban Shimon ben Gamliel said that she brought her sister-wife into her house, and our Rabbis say that she was really a harlot; and because there was some levity in him all of the people fell upon him. Therefore it is written “you shall beware of everything evil" and “If there is among you a man who is unclean…” These are Israel who became impure through idolatry, as it says “…scatter them afar like a menstruant; 'Go out,' say to it.” (Yeshayahu 30:22) “…he shall go outside the camp…” (Devarim 23:11) that they were exiled to Bavel. “And it shall be, towards evening…”(Devarim 23:12) the evening of the kingdoms, and the Holy One purifies them as it says “…he shall bathe in water…” (ibid.) and it is written “When the Lord shall have washed away the filth of the daughters of Zion…” (Yeshayahu 4:4) “…and when the sun sets…” (Devraim 23:12) When the King Messiah comes of whom it is written “…and his throne is like the sun before Me.” (Tehillim 89:37) “…he may come within the camp” (Devarim 23:12) These are Israel, entering into the Holy Temple. “And you shall have a designated place outside the camp…” (Devarim 23:13) this is the merit of Avraham. R. Pinchas said- “…so that you can go out there,” to Bavel. “And you shall keep a stake in addition to your weapons…” (Devarim 23:14) Nevuchadnezar demanded that they serve an idol and they said “…let it be known to you, O king, that we will not worship your god…” (Daniel 3:18) “…and you shall return and cover your excrement.” (Devarim 23:14) The covering of idolatry that was in Jerusalem. “For the Lord, your God, goes along in the midst of your camp…” (Devarim 23:15) The Holy One will be revealed to them immediately and saved them from the fire. “Therefore, your camp shall be holy…” (ibid.) Afterwards He will sanctify them as it says “And they shall call them the holy people, those redeemed by the Lord…” (Yeshayahu 62:12)
