'Pearls' in the Bible

Ye may not give that which is holy to the dogs, nor cast your pearls before the swine, that they may not trample them among their feet, and having turned -- may rend you.

'Again, the reign of the heavens is like to a man, a merchant, seeking goodly pearls,

in like manner also the women, in becoming apparel, with modesty and sobriety to adorn themselves, not in braided hair, or gold, or pearls, or garments of great price,

and the woman was arrayed with purple and scarlet-colour, and gilded with gold, and precious stone, and pearls, having a golden cup in her hand full of abominations and uncleanness of her whoredom,

and saying, Woe, woe, the great city, that was arrayed with fine linen, and purple, and scarlet, and gilded in gold, and precious stone, and pearls -- because in one hour so much riches were made waste!

And the twelve gates are twelve pearls, each several one of the gates was of one pearl; and the broad-place of the city is pure gold -- as transparent glass.
