5 Bible Verses about Bottomless Pit

They had over them as king the angel of the abyss; in Hebrew he is called Abaddon, in Greek, Apollyon.

Then, when they have finished testifying, the wild beast that is coming up out of the abyss will make war on them and conquer them and kill them,

The wild beast that you saw, once was but now is no more; he is going to come up out of the abyss, but he is going to be destroyed. The inhabitants of the earth, whose names from the foundation of the world have not been written in the book of life, will be astonished when they see that the wild beast once was but now is no more, and yet is to come.

Then I saw an angel coming down from heaven with the key of the abyss and a great chain in his hand. He seized the dragon, the ancient serpent, who is the devil and Satan, and bound him for a thousand years. Then he hurled him into the abyss, closed it, and sealed it over him, to keep him from leading the nations astray anymore, until the thousand years are at an end; after that he must be let loose a little while.

When the thousand years have ended, Satan will be let loose from his prison.
