'Bottomless Pit' in the Bible

And the demons begged Jesus not to order them away into the bottomless pit.

Then the fifth angel blew; and I saw a Star that had fallen upon the earth from the heavens, and to him was given the key of the bottomless pit.

He opened the bottomless pit, and from the pit rose a smoke like the smoke of a great furnace. The sun and the air grew dark because of the smoke from the pit.

They have as their king the Angel of the bottomless pit, whose name, in Hebrew, is 'Abaddon,' while, in Greek, his name is 'Apollyon' (the Destroyer).

As soon as they have completed their testimony, 'the wild Beast that ascends from the bottomless pit will make war upon them and conquer' and kill them.

The Beast that you saw was, but is not, and is about to rise out of the bottomless pit, and is on its way to destruction. Those who are living on earth will be amazed--those whose names have not been written in the Book of Life from the foundation of the world--when they see that the Beast was, but is not, and yet will come.'

Then I saw an angel coming down from Heaven, with the key of the bottomless pit and a great chain in his hand.

He flung him into the bottomless pit and locked it, and set his seal upon it; that he should not deceive the nations any more, until the thousand years were ended. After that he must be let loose for a while.
