André Cronje - God Money And The Blessed Poor стр 4.

For the kingdom of heaven is like a treasure hidden in a certain piece of land. And when someone stumbles upon it, he hides it, and for the joy thereof, he goes and sells all that he has, just to acquire that property and the treasure thereof. Again, the kingdom of heaven is like a pearl collector who found a pearl of high value and decided it's worth selling everything else just to get that one.
