In a later extended sense in intertestamental Jewish literature, the abyss was the underworld, either the abode of the dead (sheol) or eventually the realm of the rebellious spirits (Hell). In the latter sense, specifically, the abyss was often seen as a prison for demons. This usage was picked up in the New Testament.[1][4] Jesus send the Gadarene swine into the abyss (Luke 8:31) and the antichrist will rise out of the abyss (Revelation 11:7).
