Kinos 25-27: Crusades, Yirmiyahu & The Avos, The Mysterious Women
25. Mi Yitein Eini - Another Kinah over the fallen communities of the first crusade by Rav Klonimus specifically over the communities of Speyer, Worms, and Mainz. They fell in the months of Iyar and Sivan including on Shavuos over which Rav Klonimus laments that on the day we are supposed to receive the Torah it was taken instead.
26. Az Bahaloch Yirmiyahu Al Kivrei Avos - Yirmiyahu awakens the Avos, Imahos, and Moshe and pleads with them to beseech Hashem on behalf of Klal Yisroel their children to avoid the Churban. Hashem rejects each plea but promises them that He will eventually fulfill their request and that the day will come when they will be restored to their former glory.
27. Az Bimlos Sefek Yafa KaTirtza - When the Churban finally happens after years of Chait and no tshuva, Yirmiyahu leaves the Bais HaMikdash and sees a most beautiful woman dressed in such dirty clothing that he is not sure what to make of her. Is she a person or scary Malach? He finally forces her to reveal her identity and she is Knesses Yisroel which possess unparalleled raw beauty but has covered itself in the filth of sin. She urges Yirmiyahu to intercede and stop the impending doom that is about to strike Klal Yisroel.
