8334. 'And Jehovah brought the waters of the sea back over them' means that the falsities arising from evils which they aimed at the good recoiled on themselves, at the Lord's presence among those governed by good. This is clear from the meaning of 'Jehovah brought the waters of the sea back over them' as the fact that the falsities of evil which they aimed at the good recoiled on themselves.
Falsities arising from evils are gathered into one and poured into those ruled by evil, who are then surrounded by them, see 8146.
The falsities arising from evil which they aim at others recoil on themselves, in accordance with the law of order, 8214, 8223, 8226.
Being surrounded by the falsities of evil is being cast into hell, 8210, 8232.
This happens as a result simply of the Lord's presence among the good, by which He protects them and endows them with heaven and the joy of heaven, 8137 (end), 8265.
