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.
John 6:51-58
51
I am the living bread which came down out of heaven. If anyone eats of this bread, he will live forever. Yes, the bread which I will give for the life of the world is my flesh."
52
The Jews therefore contended with one another, saying, "How can this man give us his flesh to eat?"
53
Jesus therefore said to them, "Most certainly I tell you, unless you eat the flesh of the Son of Man and drink his blood, you don't have life in yourselves.
54
He who eats my flesh and drinks my blood has eternal life, and I will raise him up at the last day.
55
For my flesh is food indeed, and my blood is drink indeed.
56
He who eats my flesh and drinks my blood lives in me, and I in him.
57
As the living Father sent me, and I live because of the Father; so he who feeds on me, he will also live because of me.
58
This is the bread which came down out of heaven--not as our fathers ate the manna, and died. He who eats this bread will live forever."
