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.
Numbers 18:8-20
8
Yahweh spoke to Aaron, "I, behold, I have given you the command of my wave offerings, even all the holy things of the children of Israel; to you have I given them by reason of the anointing, and to your sons, as a portion forever.
9
This shall be yours of the most holy things, [reserved] from the fire: every offering of theirs, even every meal offering of theirs, and every sin offering of theirs, and every trespass offering of theirs, which they shall render to me, shall be most holy for you and for your sons.
10
You shall eat of it like the most holy things. Every male shall eat of it. It shall be holy to you.
11
"This is yours, too: the wave offering of their gift, even all the wave offerings of the children of Israel. I have given them to you, and to your sons and to your daughters with you, as a portion forever. Everyone who is clean in your house shall eat of it.
12
"All the best of the oil, and all the best of the vintage, and of the grain, the first fruits of them which they give to Yahweh, to you have I given them.
13
The first-ripe fruits of all that is in their land, which they bring to Yahweh, shall be yours; everyone who is clean in your house shall eat of it.
14
"Everything devoted in Israel shall be yours.
15
Everything that opens the womb, of all flesh which they offer to Yahweh, both of man and animal shall be yours: nevertheless you shall surely redeem the firstborn of man, and you shall redeem the firstborn of unclean animals.
16
You shall redeem those who are to be redeemed of them from a month old, according to your estimation, for five shekels of money, after the shekel of the sanctuary (the same is twenty gerahs).
17
"But you shall not redeem the firstborn of a cow, or the firstborn of a sheep, or the firstborn of a goat. They are holy. You shall sprinkle their blood on the altar, and shall burn their fat for an offering made by fire, for a pleasant aroma to Yahweh.
18
Their flesh shall be yours, as the wave offering breast and as the right thigh, it shall be yours.
19
All the wave offerings of the holy things, which the children of Israel offer to Yahweh, have I given you, and your sons and your daughters with you, as a portion forever: it is a covenant of salt forever before Yahweh to you and to your seed with you."
20
Yahweh said to Aaron, "You shall have no inheritance in their land, neither shall you have any portion among them. I am your portion and your inheritance among the children of Israel.
