'Waters' particularly signify the spiritual parts of a person, or the intellectual aspects of faith, and also their opposites.

'The waters above the firmament,' as in Genesis 1:7, signify the knowledges in the internal self, and 'the waters beneath the firmament' signify the knowledges of the external self.

'Waters,' as in Ezekiel 47:9, refer to the New Jerusalem, and they signify spiritual things from a celestial origin.

'Many waters,' as in Revelation 17:1, signify truths of the Word adulterated. 'Waters' or 'rivers' signify spiritual, rational, or scientific things pertaining to truth.

'Waters … that go softly,' as in Isaiah 8:6-7, signify spiritual things, and 'waters … strong and many,' signify falsities.

'Waters,' as in Psalms 104:3, signify divine truths.

'Waters' signify truths in the natural self, and in the opposite sense, falsities.

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.
