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.
Matthew 12:24-28
24
But when the Pharisees heard it, they said, "This man does not cast out demons, except by Beelzebul, the prince of the demons."
25
Knowing their thoughts, Jesus said to them, "Every kingdom divided against itself is brought to desolation, and every city or house divided against itself will not stand.
26
If Satan casts out Satan, he is divided against himself. How then will his kingdom stand?
27
If I by Beelzebul cast out demons, by whom do your children cast them out? Therefore they will be your judges.
28
But if I by the Spirit of God cast out demons, then the Kingdom of God has come upon you.
