8277. 'Have been drowned in the Sea Suph' means that they have shut themselves up in falsities arising from evil. This is clear from the meaning of 'being drowned', here by the waters of the Sea Suph, as shutting themselves up in falsities arising from evil. For falsities are meant by 'the waters' of that sea, 8137, 8138, and being shut up in by 'being drowned', since those in the hells are shut in and surrounded by falsities in the way that those being drowned are by water. Regarding their plunging themselves into those falsities, or shutting themselves up in them, see 7926, 8227, 8228.
