In the Bible, "666" is a reference to 1 Kings 10:14 where King Solomon was given 666 talents of gold. "666" is a reference to wealth. In the King James Bible, the Mark of the Beast is said to be placed IN the forehead or right hand (like a microchip), but in later versions it was changed to "on" (like a tattoo). Funny thing is, not only can RFID technology be used to make cashless payments, but it can either be implanted in the skin or made into a peelable "tattoo" (see Bill Gates who's pushing for "smart tattoos" to replace traditional IoT). The antichrist, if he were alive today, could either be Donald Trump, Elon Musk or Jared Kushner.
There's a website called gematrix.org. it lets you search any keyword and see its resonance in Hebrew Gematria, English Gematria and Simple Gematria. Gematria is more symbolic, but its relevant because Hebrew, like Runic scripts, is not only a language, but a numerical system (see Pentadic numerals and Cicada 3301 for more info on Runes).
Does anyone in here understand Gematria?
