How much is the pearl worth?

  Woe is me, my mother, that you ever bore me, a man of strife and contention to the whole land! I have not lent, nor have I borrowed, yet all of them curse me.

Your words were found, and I ate them,
and your words became to me a joy
and the delight of my heart;
for I am called by your name,
O LORD, God of hosts.
I did not sit in the company of merrymakers,
nor did I rejoice;
under the weight of your hand I sat alone,
for you had filled me with indignation.
Why is my pain unceasing,
my wound incurable,
refusing to be healed?
Truly, you are to me like a deceitful brook,
like waters that fail.
 
   Therefore thus says the LORD:
If you turn back, I will take you back,
and you shall stand before me.
If you utter what is precious, and not what is worthless,
you shall serve as my mouth.
It is they who will turn to you,
not you who will turn to them.
And I will make you to this people
a fortified wall of bronze;
they will fight against you,
but they shall not prevail over you,
for I am with you
to save you and deliver you, says the LORD.
I will deliver you out of the hand of the wicked,
and redeem you from the grasp of the ruthless.
 
Matthew 13:44-46

  “The kingdom of heaven is like treasure hidden in a field, which someone found and hid; then in his joy he goes and sells all that he has and buys that field.

  “Again, the kingdom of heaven is like a merchant in search of fine pearls; on finding one pearl of great value, he went and sold all that he had and bought it.
