For what it's worth, Revelation 20:1-3 ASV says this:
quote: 1 And I saw an angel coming down out of heaven, having the key of the abyss and a great chain in his hand.
2 And he laid hold on the dragon, the old serpent, which is the Devil and Satan, and bound him for a thousand years,
3 and cast him into the abyss, and shut it, and sealed it over him, that he should deceive the nations no more, until the thousand years should be finished: after this he must be loosed for a little time.
I'm not making any determination on this. When I read that chapter black holes come to mind.
Where is a bottomless pit mentioned in your quote?
Anyone so limited that they can only spell a word one way is severely handicapped!
