Footnote 4 – Why 2K?
The Greek system is very similar to the Hebrew. The Greek alphabet has 26 letters. But in determining the numerical value of the letters, the symbol stigma, which is not a letter, was (for unknown reasons) inserted in the sixth position. In the Greek alphabet the first nine letters (including stigma) equal one through nine. The next nine rise by 10s, and the last nine rise by 100s.
