What is Wisdom?

My son, if you receive my words
and treasure up my commandments with you,
2 making your ear attentive to wisdom
and inclining your heart to understanding;
3 yes, if you call out for insight
and raise your voice for understanding,
4 if you seek it like silver
and search for it as for hidden treasures,
5 then you will understand the fear of the Lord
and find the knowledge of God.
6 For the Lord gives wisdom;
from his mouth come knowledge and understanding;

Proverbs 2:1-6 ESV
