Mat 13:45 Again, the kingdom of heaven is like a merchant man, seeking goodly pearls:
Mat 13:46 Who, when he had found one pearl of great price, went and sold all that he had, and bought it.

Here, the pearl is a symbol of the intellectual realm. As in "pearls of wisdom" or "pearls before swine," it is Christs symbol for powerful intellectual ideas. The lesson here is a little different from the last because the sense of selling here is more negative.

Symbol translated version: And the power of spirit is like a traveler seeking beautiful pearls of wisdom, who, when he found one pearl of great value, left and sold out everything he had and did business for it.

"Goodly" is from kalos, which means "beautiful."

"Merchant man" is from emporos, which means "a traveler," "a merchant," and "a dealer."

"Great price" is from polutimos, which means "much revered" and "highly priced."

Interestingly, the word for "sold" is different than the last verse (pôleô , which means "to exchange" or "barter"). Here it is pipraskô, which also means "to sell." "to trade," or "to export," but which is specifically used to mean selling into slavery, to sell for a bribe, and is a metaphor for being betrayed or ruined.
