THIS MIGHT SURPRISE YOU
The answer
Angels who sinned. "God did not spare the angels when they sinned but cast them into hell and committed them to chains of deepest darkness to be kept until the judgment" (2 Peter 2:4). The Greek word under "hell" in that verse is tartarus.
Why it’s interesting
It is the only place in the New Testament where tartarus appears. Jude has angels kept "in eternal chains in deepest darkness for the judgment of the great day," without the word (Jude 1:6).
