Donna,
2+2=4 , it doesn't equal 3 or 5. If the Bible says the number of the beast is 666, it "ain't" 660. The Bible doesn't say in Rev. 13:18 chi xi or 660. It says χξϚ = chi xi stigma or 666.
The Greek Ordinal-6 Gematria (that is alpha = 6, beta = 12, --->**omega = 156) of ΧουσεÎν or Hussein is 666.
ΜπαÏάκ Ομπάμα or Greek for Barack Obama is 738. 738 = 666+66+6.
**Note - The 6th (stigma or digamma) and the 19th (koppa) letters of the Greek alphabet are no longer used but do count as these Greek numerical values.
stigma = Ordinal-1 (6), Standard (6) or Ordinal-6 (36)
koppa = Ordinal-1 (19), Standard (90) or Ordinal-6 (114)
This is my 'understanding' anyway.
In Christ,

P.S. The Ordinal-1 English value of BARACK is 36 which is the 8th Triangular Number, is the triangular root of 666 .
