Wise?

Ok, so I am reading through Proverbs and I had this thought. Please don't expect anything profound here. . .
"In the house of the wise are stores of choice food and oil, but a foolish man devours all he has. " Proverbs 21: 20.
I was thinking (and I realize that I am straying from the original intent) that wise people gather knowledge, test it against the Word, and that which is not destroyed, is stored away to be put in practice. They are wise not just because they have the knowledge, but because they test it and will put it into action. On the contrary, a fool is someone who gathers knowledge from everywhere and anywhere. He doesn't test it to be sure that it is choice food, but instead takes in everything that he can, simply because it is there in front of him. When we eat, we are sending nourishment deep into our being. The same goes with knowledge - what we let in goes deep within us and shapes us. Are we going to eat of truth or the world's lies???? Prime Rib or bologna?
