Pot
Pots" and other large vessels in the Bible represent facts and factual ideas, which serve as containers for truth the same way pots serve as containers for water or wine. Pots fill their function because they are hard, strong and impervious; facts are also absolute and unchanging, filling their function the same way. And pots must be filled to serve any use, just as facts must be filled with truth to serve any purpose. To some extent this meaning also applies to cups, bowls and other smaller vessels, though it is a little more immediate. Generally you don't fill a cup so you can store a liquid; you fill it to drink it. Smaller vessels then often take more of their meaning from the substance they contain, and in many cases ("cup" and "wine" especially) actually mean the same thing.
Arcana Coelestia # 5336
5336. 'When he stood before Pharaoh king of Egypt' means the presence of the celestial of the spiritual in the natural. This is clear from the meaning of 'standing before someone' as the presence, and from the representation of 'Pharaoh king of Egypt' as a new state in the natural or a new natural man, dealt with in 5079, 5080, and so the natural which now had the celestial of the spiritual within it and which the celestial of the spiritual now made its own - which is also the meaning of the words that immediately follow, 'And Joseph came out from before Pharaoh'.
