Midrash su Giudici 11:1

“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)

“The young woman who will please the king will reign in place of Vashti. The proposal pleased the king and he did so” (Esther 2:4).
“The young woman who will please the king” – who is fitting for this thing? ¹⁵Fit to raise the woman who would be chosen as queen. Mordekhai – “there was a Jewish man in the Shushan citadel, and his name was Mordekhai” (Esther 2:5).¹⁶This is the immediately following verse. This and the subsequent passages are all cases where the midrash addresses the juxtaposition of two verses. It asks about the first verse: who is fitting for this thing? It then finds the answer in the next verse.
Similarly, “God saw the children of Israel and God knew” (Exodus 2:25). Who is fitting for this matter? Moses – “And Moses was herding” (Exodus 3:1).
Similarly, “Samuel said to the men of Israel: Go, each man to his city” (I Samuel 8:22). Who is fitting for this thing [to be appointed king]? Saul, as it is stated: “There was a man of Benjamin, and his name was Kish…[and he had a son and his name was Saul…]” (I Samuel 9:1–2).
Similarly, “Saul and all Israel heard these words of the Philistine, and they were dismayed and were greatly afraid.” (I Samuel 17:11). Who is fitting for this thing [fighting Goliath]? David – “David was the son of that Efrati [from Bethlehem]” (I Samuel 17:12).
Rabbi Yehoshua bar Aviram said two things. It is written: “He [Yavin king of Canaan] oppressed the children of Israel strongly [beḥozka] for twenty years” (Judges 4:3). What is beḥozka? Rabbi Yitzḥak said: With cursing and blaspheming. That is what is written: “Your words have been harsh against Me” (Malachi 3:13). Who is fitting for this thing? Deborah, as it is written: “Deborah was a prophetess, wife of Lapidot” (Judges 4:4).
Rabbi Yehoshua bar Aviram said another: “The people, the princes of Gilad, said one to another: Who is the man who will begin to wage war against the children of Amon? He will be the head of all the inhabitants of Gilad” (Judges 10:18). Who is fitting for this thing? Yiftaḥ – “Yiftaḥ the Giladite was a mighty warrior” (Judges 11:1).
