Mandaic (Aramaic Hebrew)

Mandaic (Aramaic Hebrew) Alphabet
Mandaic (Aramiac has 24 letters. There are 24 hours in a day:  
The alphabet consists of 24 letters: the 22 letters of the Aramaic alphabet with two additional letters at the end. As the number 24 is auspicious for Mandaeans (it is the number of hours from sunset to sunset), the additional letters are somewhat artificial. The 23rd letter is adu, the relative particle (cf. Arabic tāʾ marbūṭa, Coptic letter "ti", and English ampersand). And the 24th is the first letter, a, repeated. Thus, Mandaeans say that the abagada has perfected the alpha and omega. http://en.wikipedia.org/wiki/Mandaic_alphabet
The Mandaic alphabet is also a creation story starting with Highest, leading to First Cry and then Penitence (q.v. under See Also).
