Temurah & Notarikon
Applies the letter exchanges Atbash, Albam, Atbah and Avgad to Hebrew text with gematria values, reads each letter through Aiq Bekar’s nine chambers, and finds notarikon: a phrase’s initials, and the runs of words in the Tanakh a word’s letters begin, against chance. Atbash appears in Jeremiah 25:26 (Sheshach for Babel); the Talmud lists the Atbash and Albam pairs (Shabbat 104a) and reads אנכי as notarikon (105a).
