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.

5320. 'And placed a chain of gold onto his neck' means an outward sign denoting the joining of interior things to exterior ones, good being that which effects that joining together. This is clear from the meaning of 'the neck' as a flowing in, also the communication of higher things with lower ones, or what amounts to the same, interior things with exterior ones, dealt with in 3542; and therefore 'a chain', because it goes around the neck, is a sign denoting the joining together of those things. 'A chain of gold' means a joining together by means of good; that is, good is the means which effects it, because 'gold' means good, 113, 1551, 1552. A sign denoting the joining of interior truth to exterior truth is meant by 'a chain onto the neck' in Ezekiel,

I adorned you with ornaments and put bracelets onto your hands and a chain onto your neck. Ezekiel 16:11.
