'Pearls' in the Bible

“For wisdom is better than rubies;And all desirable things cannot compare with her.

There is gold, and an abundance of pearls,But the lips of knowledge are a vessel of preciousness [the most precious of all].

An excellent woman [one who is spiritual, capable, intelligent, and virtuous], who is he who can find her?Her value is more precious than jewels and her worth is far above rubies or pearls.
