616 or 666?

Just a mini-post today. A small reminder of something most of you probably know.

We all are familiar with this verse from Revelation:

This calls for wisdom. If anyone has insight, let him calculate the number of the beast, for it is man's number. His number is 666. (Rev. 13:18)

The problem is, some very early manuscripts contain not 666 but 616! Think of all the Herculean efforts that have gone to waste in symbology and numerology.
