In the Bible, the abyss is an unfathomably deep or boundless space. The term comes from the Greek ἄβυσσος, meaning bottomless, unfathomable, boundless.[1] It is used as both an adjective and a substantive.[2] It appears in the Septuagint, the earliest Greek translation of the Hebrew Bible, and in the New Testament. It translates the Hebrew words tehom (deep), tsulah (sea-deep, deep flood) and rachabh (spacious place).[2]
