[B-4]  Numerical Values of Hebrew & Greek Letters
 

The Hebrew alphabet consists of 22 (2x11) letters with 5 "finals" added to make up three series of 9; 27 in all:
 
א Aleph =   1          י Yod =     10            ק Koph =          100
ב Beth =    2          כ Kaph =    20            ר Resh =          200
ג Gimel =   3          ל Lamed =   30            ש Shin =          300
ד Daleth =  4          מ Mem =     40            ת Tau =           400
ה He =      5          נ Nun =     50            ך Koph {final} =  500
ו Vau =     6          ס Samech =  60            ם Mem {final}=    600
ז Zayin =   7          ע Ayin =    70            ן Nun {final} =   700
ח Cheth =   8          פ Pe =      80            ף Pe {final}=     800
ט Teth =    9          צ Tsaddi =  90            ץ Tsaddi{final} = 900
 

The Greek letters were 24 so the required number -- 27 was made up by using the final " ς" call Stigma for 6, and adding two arbitrary symbols called Koppa с for 90, and Sampsi э for 900. {Note: the Koppa and Sampsi are not exactly replicated here due to the lack of a font that contains them.}

α Alpha =   1        ι Iota =    10        ρ Rho =      100
β Beta =    2        κ Kappa =   20        σ Sigma =    200
γ Gamma =   3        λ Lambda =  30        τ Tau =      300
δ Delta =   4        μ Mu =      40        υ Upsilon = 400
ε Epsilon = 5        ν Nu =      50        φ Phi =     500
ς Stigma =  6        ξ Xi =      60        χ Chi =      600
ζ Zeta =    7        ο Omicron = 70        ψ Psi =      700
η Eta =     8        π Pi =      80        ω Omega =    800
θ Theta =   9        с Koppa =   90        э Sampsi =   900

"The letter ς (called Stigma) is used for the number 6. Why this letter and number should be thus associated we cannot tell, except that both are intimately connected with the ancient Egyptian "mysteries." The three letters S S S (ΣΣΣ in Greek ) were the symbol of Isis, which is thus connected with 666. Indeed the expression of this number,χξς , consists of the initial and final letters of the word χρίστος(Cristos ), Christ, viz,χ and ς , with the symbol of the serpent between them, χ -ξ - ς ." (Numbers in Scripture page 49.)
