'Abyss' in the Bible

And they began imploring him that he would not order them to depart into the abyss.

or "Who will descend into the abyss?" (that is, to bring Christ up from the dead).

And the fifth angel blew the trumpet, and I saw a star that had fallen from heaven to the earth, and the key of the shaft of the abyss was given to him.

And he opened the shaft of the abyss, and smoke went up from the shaft like smoke from a great furnace, and the sun and the air were darkened by the smoke from the shaft.

They have [as] king over them the angel of the abyss, {whose name} in Hebrew [is] Abaddon, and in Greek he has the name Apollyon.

And when they have completed their testimony, the beast that comes up from the abyss will make war with them and will conquer them and will kill them.

The beast that you saw was, and is not, and is going to come up from the abyss, and he is going to destruction. And those who live on the earth, whose names are not written in the book of life from the foundation of the world, will be astonished [when they] see the beast that was, and is not, and will be present.

And I saw an angel descending from heaven, holding the key of the abyss and a great chain in his hand.

and threw him into the abyss, and shut [it] and sealed [it] above him, in order that he could not deceive the nations again until the thousand years are completed. After these [things] it is necessary [for] him to be released [for] a short time.
