Revelation 17:11 - An Understandable Version (2005 edition)
11 And the beast that once existed, but now does not, is actually the eighth one [i.e., head/hill/king. See verse 9], and yet he belongs to the seven; and he will go to his destruction.
11 And as for the beast that [once] was, but now is no more, he [himself] is an eighth ruler (king, head), but he is of the seven and belongs to them, and he goes to perdition.
The beast you saw once existed, but now does not, and [yet] is about to come up out of the pit and go to [his] destruction. And those people living on the earth, whose names have not been recorded in the book of life from the creation of the world, will be amazed when they see the beast, because he had once existed, but now does not, and yet will come [again].
If anyone goes [or “leads others”] into captivity, he will go into captivity [himself]; if anyone is killed [or “kills others”] with the sword, he will be killed with the sword [himself]. Here is [where] God’s holy people [need] perseverance and faith.
And he exercises all the authority of the first beast [See verse 1] in his presence [or, “on his behalf”]. And he forces the earth and those who lived on it to worship the first beast, whose [apparently] fatal wound had healed.
