Pro 2:1 My son, if thou wilt receive my words, and hide my commandments with thee;
Pro 2:2 So that thou incline thine ear unto wisdom, and apply thine heart to understanding;
Pro 2:3 Yea, if thou criest after knowledge, and liftest up thy voice for understanding;
Pro 2:4 If thou seekest her as silver, and searchest for her as for hid treasures;
Pro 2:5 Then shalt thou understand the fear of the LORD, and find the knowledge of God.
I just noticed today that the word "hide" in the first verse is also the same word used in Psalm 119, which I referenced here in my post about post-it notes from God. Other translations also use "treasure" and "store up" in the same place. So we have to receive the words and hold them, not just read them and hope for the best. The things we store are things we've paid attention to at some point, and if we treasure them we continue to do so.
It is an active process of the will, not a passive accident, which we can see in the following verses. We're to incline our ear to wisdom and our heart to understanding, to cry after knowledge and lift our voice for understanding, and seek wisdom as we'd seek for silver and hidden treasure. Think of how fast we would move to find hidden treasure if we knew it was right there for us to find!
And wisdom is there to find. In the first chapter we find wisdom as a woman, crying out in the streets and all over the city. James 1:5 tells us to acquire wisdom, all we need to do is ask God, in faith, and it will be given. It is right there for us to find and pay attention to!
