Arcana Coelestia # 8138
8138. 'In Pharaoh and in all his army' means the submersion into hell of those steeped in falsities arising from evil, and their encompassment there by falsities as if by waters. This is clear from what has been mentioned immediately above in 8137, that 'Pharaoh' means those who were cast into hell, as also does 'his army', 'Pharaoh' being those steeped in falsities arising from evil, and 'his army' the falsities themselves. 'Armies' are truths springing from good, see 3448, 7236, 7988, and therefore in the contrary sense they are falsities arising from evil, 3448. The expression 'encompassment by falsities as if by waters' is used because falsities that arise from evil - the kind of falsities that exist with those belonging to the Church who have championed separated faith and have led a life of evil - are seen there as waters, 8137. This also is why deluges of water mean situations in which truth is laid waste while the water present in them means falsities, 705, 739, 756, 6346, 6853.
Arcana Coelestia # 6346
6346. 'Light as water' means that faith alone does not possess such qualities, neither glory nor powerfulness. This is clear from the meaning of 'being light as water' as having no weight or worth. The fact that faith alone is meant, that is, faith separated from charity, is evident from the things mentioned in what follows that involve Reuben, and that involve Simeon and Levi. Those men - Reuben, Simeon, and Levi - are used here also to refer to faith alone or faith separated from charity.
