Looking at the wording in Rev. ch. 13, it seems to me that 666 is not necessarily the number of the Antichrist whom Christ shall destroy; but it IS definitely the number of "a man" who is understood to have a connection with the Earth-Beast entity which causes people to take the Mark unto people.Btw, the name of WHO's director-general written like Hebrew names, i.e. with only consonants and semivowels (y, w/u) = gbrysus = 666 in English gematria
* "to take the Mark."
