Revelation 17:7-13

and the angel said: Why are you so amazed? I will explain the mystery about this woman and about the beast she is sitting on, with its seven heads and ten horns. The beast you saw is one that used to be and no longer is. It will come back from the deep pit, but only to be destroyed. Everyone on earth whose names were not written in the book of life before the time of creation will be amazed. They will see this beast that used to be and no longer is, but will be once more. Anyone with wisdom can figure this out. The seven heads that the woman is sitting on stand for seven hills. These heads are also seven kings. Five of the kings are dead. One is ruling now, and the other one has not yet come. But when he does, he will rule for only a little while. You also saw a beast that used to be and no longer is. That beast is one of the seven kings who will return as the eighth king, but only to be destroyed. The ten horns you saw are ten more kings, who have not yet come into power, and they will rule with the beast for only a short time. They all think alike and will give their power and authority to the beast.
