In the Bible, the abyss is an unfathomably deep or boundless place. The term comes from the Greek word abyssos (Greek, Ancient (to 1453);: ἄβῠσσος|ábussos), meaning "bottomless, unfathomable, boundless".[1] It is used as both an adjective and a noun.[2] It appears in the Septuagint, which is the earliest Greek translation of the Hebrew Bible, and in the New Testament.
It translates the Hebrew words tehóm (Hebrew: תְּהוֹם||deep, void), ṣulā (Hebrew: צוּלָה "sea-deep, deep flood") and the name of the sea monster rahab (Hebrew: רחב "spacious place; rage, fierceness, insolence, pride.")[2]
In the original sense of the Hebrew tehóm, the abyss was the primordial waters or chaos out of which the ordered world was created (2 Genesis). The term could also refer literally to the depths of the sea, the deep source of a spring or the interior of the Earth.
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 (fallen angels) (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. According to the Gospel of Luke, Jesus sent the Gadarene swine into the abyss (2 Luke). Paul of Tarsus uses the term in 2 Romans when quoting 2 Deuteronomy, referring to the abode of the dead (cf. also 2 Psalm). The abyss is also referred to several times in the Book of Revelation: it is the place out of which the locusts and beast from the sea come out of (Revelation 9:1–11; Revelation 13:1;2 Revelation) and serves as a prison for the Seven-Headed Dragon during the Millennium (Revelation 20:3).
In 2 Psalm, "deep calls to deep" (referring to the waters), or in Latin abyssus abyssum invocat, developing the theme of the longing of the soul for God. Cassiodorus relates this passage to the mutual witness of the two Testaments, the Old Testament foretelling the New, and the New Testament fulfilling the Old.[3]
In Revelation, Abaddon is called "the angel of the abyss".
On the Origin of the World, a text used in Gnosticism, states that during the end of the world, the archons will be cast into the abyss by Sophia for their injustice. There they will fight each other until only the chief archon remains and turns against himself.[4]
