pasuk with all the letters: Zeh hadavar asher tziva Hashem.. in parshas hamon.
For out of the box thinkers: where in Mikra do we have the same
word 31 times in a row. (two examples)
Esav says to Yaakow “hal’iteni na min haadom haadom hazeh” The verb lamed ayin tes, according to Ibn Ezra, is an ain lo chaver bemikra. (the middle degree of rarity) Where does this verb show up in the Halacha? I have asked this ? to gedolim ve’shalemim, and never got a reply without extensive coaching.
A riddle apparently without an answer: In Shoftim tes, Avimelech ben Yerubeshes is laying siege to the town of Tevetz. The people take refuge in a tower, Avimelech approches the door to burn it, and a woman, nameless except for the term ONE WOMAN ( isha achas) aims a millstone at his head and scores a hit. Many years later ( I did not work out the time line) when Yoav is setting up Uriya Hachiti on the front line, Yoav sends a messenger to David Hamelech, prepared for the expected argument “why did you send them to the wall… Who killed ABY, it was A WOMAN who cast a millstone on him.. This woman entered military history and Strategy 101 for all time. The attachment “achas” or “ehad” is generally indicates a known or unique individual, and the meforshim generally list the identity. Ex. veisha achas mineshe bene haniviim, she is identified as Mrs. Ovadiah. The rock thrower, however famous, remains nameless, at least to my thorough searches.
