'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.

8049. 'Remember this day on which you came out of Egypt, out of the house of slaves' means that especially should they call to mind that state which was theirs when they were delivered from spiritual captivity by the Lord. This is clear from the meaning of 'remember' as that they should call to mind; from the meaning of 'day' as state, dealt with in 23, 487, 488, 493, 893, 2788, 3462, 3785, 4850, 5672, 5962, 7680; from the meaning of 'coming out' as being delivered, for the exodus of the children of Israel means the deliverance by the Lord of those belonging to the spiritual Church, regarding which deliverance see 6854, 6914, 7091 (end), 7828, 7932, 8018; and from the meaning of 'Egypt' and 'the house of slaves' as spiritual captivity. For 'Pharaoh' and 'the Egyptians' mean those in the next life who molested spiritual people by means of falsities, 7097, 7107, 7110, 7126, 7142, 7220, 7228, 7317, and therefore 'the land of Egypt' means molestation, 7278. Molestation by means of falsities is nothing else than spiritual captivity, for when people suffer molestation they are held captive so to speak in falsities from which they constantly strive to be delivered. This also explains why they are called in the Word 'the bound in the pit', 6854. That spiritual captivity is what is also meant by 'the house of slaves (or servants)'. 'Slavery' (or service) means being under attack from falsities, which is molestation, see 7120, 7129.
