In Matthew 13: 45,46 Jesus said:
Again, the kingdom of heaven is like a merchant looking for fine pearls.When he found one of great value, he went away and sold everything he had and bought it.
In part 1 we saw that the kingdom of heaven was like a man (Jesus) finding a treasure (the Jews) in a field (the world). In this next parable the kingdom is likened to a merchant looking for fine peals.
Pearls were not known or valued by Jews at that time (they’re only mentioned once in the Old Testament) so Jesus’ audience was probably frowning at one another at that point though they understood that the Greek word here, margarites, meant pearl or proverb (word of great value).
