Wisdom is worth more than precious gems. Ask God and He will give you liberal amounts of it. (James 1:5)

Proverbs 8:

Listen as Wisdom calls out!
    Hear as understanding raises her voice!
² On the hilltop along the road,
    she takes her stand at the crossroads.
³ By the gates at the entrance to the town,
    on the road leading in, she cries aloud,
⁴ “I call to you, to all of you!
    I raise my voice to all people.
⁵ You simple people, use good judgment.
    You foolish people, show some understanding.
⁶ Listen to me! For I have important things to tell you.
    Everything I say is right,
⁷ for I speak the truth
    and detest every kind of deception.
⁸ My advice is wholesome.
    There is nothing devious or crooked in it.
⁹ My words are plain to anyone with understanding,
    clear to those with knowledge.
¹⁰ Choose my instruction rather than silver,
    and knowledge rather than pure gold.
¹¹ For wisdom is far more valuable than rubies.
    Nothing you desire can compare with it.
