Revelation 17:6-8

Amplified Bible

⁶ I saw that the woman was drunk with the blood of the saints (God’s people), and with the blood of the witnesses of Jesus [who were martyred]. When I saw her, I wondered in amazement. ⁷ But the angel said to me, “Why do you wonder? I will explain to you the mystery of the woman and of the beast that carries her, which has the seven heads and ten horns.

⁸ “The beast that you saw was [once], but [now] is not, and he is about to come up out of the abyss (the bottomless pit, the dwelling place of demons) and go to destruction (perdition). And the inhabitants of the earth, whose names have not been written in the Book of Life from the foundation of the world, will be astonished when they see the beast, because he was and is not and is yet to come [to earth].^(A)
