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 # 683
683. As regards the use twice of the verb 'did' comprehending both good and truth, it should be recognized that in the Word, especially the Prophets, one matter may be described in two ways, as in Isaiah,
He has passed on in peace, a way He has not gone with His feet. Who has performed and done this? Isaiah 42:3, 4.
Here the first statement has regard to good, the second to truth, that is to say, the first regards things of the will, the second those of the understanding. Thus 'passing on in peace' embodies things of the will, 'a way he did not go with His feet' those of the understanding. The same applies to 'performing' and 'doing'. In the Word things that belong to the will and to the understanding, that is, to love and faith - or what amounts to the same, celestial things and spiritual things - are joined together in such a way that each individual part images a marriage, and answers to the heavenly marriage. The same applies here with the repetition of the same verb.
