The older system of number-letter equivalents omits the number 9. It was omitted because it was held to be of special significance; in the Cabalistic tradition it was considered to be the numerical equivalent of the name of God.

1 2 3 4 5 6 7 8

The more modern system of equivalents uses all the primary numbers, including the number 9.
