If you are reading the KJV you will notice that this verse talks about “wisdom” (7922) while the NASB uses “insight”. I point this out because this is not the most common Hebrew word for “wisdom” in Proverbs but it is what might be called a “nuance word”, it gives us some understanding of what wisdom is.
Here the definition involves insight and prudence. It almost seems to be emphasizing the practical aspect of wisdom. It is something that can be applied and used. The words from this wisdom actually mean something and help. Often when I read fantasy or any genre that deals with the world of magic and the occult, wisdom is vague and mysterious. It is held in awe but does nothing but confuse. This points out the rubber meets the road aspect of real wisdom.
So? What the Bible teaches us is useful for what we do in our everyday lives.
(2 Timothy 3:16 KJV) All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:It isn’t a tool for impressing people. It is a tool for guidance. And again I remind you that the tool is useless to you if it isn’t in your tool chest.
