Wisdom, better than Gold, Silver and Rubies

Proverbs 8:10-11

And knowledge rather than choice gold;
11 For wisdom is better than rubies,
And all the things one may desire cannot be compared with her.

And my revenue than choice silver.

And to get understanding is to be chosen rather than silver.

15 There is gold and a multitude of rubies,
But the lips of knowledge are a precious jewel.
