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.
Colossians 2:1-3
1
For I desire to have you know how greatly I struggle for you, and for those at Laodicea, and for as many as have not seen my face in the flesh;
2
that their hearts may be comforted, they being knit together in love, and gaining all riches of the full assurance of understanding, that they may know the mystery of God, both of the Father and of Christ,
3
in whom are all the treasures of wisdom and knowledge hidden.
