8299. 'In the mighty waters' means surrounded by a vast quantity of falsities. This is clear from the meaning of 'waters' as falsities arising from evil, dealt with just above in 8297, so that 'the mighty waters' are falsities in a vast quantity. The fact that they were surrounded or hemmed in by them, see 8210, 8232.

8297. 'The sea covered them over' means that all the falsity they possessed hemmed them in. This is clear from the meaning of 'covering over' as hemming in; and from the meaning of 'the sea', here the waters of the Sea Suph, as falsities arising from evils, which sea also means hell, dealt with in 8099, 8137, 8138, 8148. As regards their being hemmed in there by falsities arising from evil, [see] 8210, 8232.
