“Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number is Six hundred threescore and six.”
King James Version (KJV)
Re 13:18 THE NUMBER OF THE BEAST. Let him that hath understanding count the number of the beast. Re 13:17 speaks of "the name of the beast". It has, then, a name. It also speaks of the number of its name. Its name, then, is some number. We wish to discover its name, and if we can count the number, we will find its name. "The number of the beast", that is, the "number of its name" (Re 13:17) is the number of a man, and that number is "six hundred and sixty-six".
