Why does Hester name her child Pearl? Of what might the name be symbolic?

I
believe that early in the novel it is explained thatnamed her daughteras anto ain the New
Testament, which I quote here from Matthew 13:45-46 in the King James Bible:

45 Again, the kingdom of heaven is like unto a merchant
man, seeking goodly pearls:

46 Who, when he had found one pearl of great
price, went and sold all that he had, and bought it.

Hester has had to give up a great deal for the sake of her little girl, but she
considers it worth the sacrifice because her daughter is so precious to her. The little girl
does indeed seem like a pearl because she is beautiful and angelic. It is ironic that such a
lovely child should be regarded as a source of shame and disgrace. She compensates with Hester
for the ostracism and humiliation she has to endure, which is symbolized by the scarlet letter
she is forced to wear.
