ἄβυσσος. In [Rom 10:7] ’the deep’ probably refers to the deep sea, for in [Deu 30:13] (from whence the quotation is made) it is "Who shall go over the sea for us?" and the sea is called ’the deep’ elsewhere, as [Isa 51:10]; [Isa 63:13], etc. In [Luk 8:31] ’the deep’ refers to the abyss where evil spirits are confined. It is probably the place where the fallen angels are reserved in chains of darkness, [2Pe 2:4], where the reference is to tartarus, not gehenna. See BOTTOMLESS PIT.
