Here is a call for wisdom: Let him who has understanding calculate the number of the beast. It is the number of a man. His number is six hundred and sixty-six.
Then the angel said to me, “Why do you marvel? I will tell you the mystery of the woman and of the beast that carries her, which has the seven heads and the ten horns.
Then he carried me away in the Spirit into the wilderness. I saw a woman sitting on a scarlet beast which was full of blasphemous names, having seven heads and ten horns.
I stood on the sand of the sea. And I saw a beast rising out of the sea, having seven heads and ten horns, with ten crowns on his horns, and blasphemous names on his heads.
Whoever is wise, let him understand these things; whoever prudent, let him know them. For the ways of the Lord are right, and the just will walk in them; but the transgressors stumble in them.
