abyss

Definition:

The term "abyss" refers to a very large, deep hole or chasm that has no bottom.

In the Bible, "the abyss" is a place of punishment.
For example, when Jesus commanded evil spirits to come out of a man, they begged him not to send them to the abyss.
The word "abyss" could also be translated as "bottomless pit" or "deep chasm."
This term should be translated differently from "hades," "sheol," or "hell."
