The Treasure and the Pearl

In one of his parables found in the Bible, Jesus described the kingdom of heaven.

The kingdom of heaven is like treasure hidden in a field, which a man found and covered up; then in his joy he goes and sells all that he has and busy that field. Again, the kingdom of heaven is like a merchant in search of fine pearls, who, on finding one pearl of great value, went and sold all that he had and bought it. (Matthew 13:44-46)
