LEB-KAMAI. In Jeremiah 51:1 is a phrase ‘in the midst of them which rise up against me’ (Heb. leb-qamai ). This is generally recognized as being an example of the Kabbalistic rule of hermeneutics whereby a cipher word was obtained by taking the letters of the alphabet in the reverse order, the last for the first, the last but one for the second, and so on. By this process (known as Atbash), leb-qamai gives us Kasdim (the Chaldæans).
