This is very impressive!  *proudly bestows the sci.math Biblical
Scholarship Award upon Victor Miller*  :-)

I've heard that letters of the Hebrew alphabet all have numerical
equivalents, which were used in ancient scriptures as the basis of a number
system.  I would be interested in knowing more about this, since it must
surely qualify as a very early example of a number system.  Doesn't some
ambiguity occasionally arise as to whether a given string of characters
should be interpreted as a word or as a numerical quantity?

Didn't classical Greek also assign numerical values to the letters of the
alphabet and employ a similar number system?  (For example, there is a New
Testament passage that speaks of "the *number* of his name" in reference to
the anti-Christ.)

Thanks,
