Arcana Coelestia #8277
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.

8228. 'And Jehovah overturned the Egyptians into the middle of the sea' means that in so doing they cast themselves into the hell where the falsities arising from evil existed. This is clear from the meaning of 'overturning them into the sea' as casting them into falsities arising from evil; for these falsities are meant by the waters of that sea, 6346, 7307, 8137, 8138. For more about the bad things which in the literal sense of the Word are attributed to Jehovah or the Lord - that the origin of them lies with the people themselves who are ruled by evil, and not at all with the Lord, and that this is how one should understand the Word in its internal sense - see 2447, 6071, 6991, 6997, 7533, 7632, 7643, 7679, 7710, 7877, 7926, 8227.
