Let's read the first four verses. These verses are just the introduction to the book of Proverbs, and they tell us the purpose of this book. Proverbs 1: 2 - 4 (CEV) says, "Proverbs will teach you wisdom and self-control and how to understand sayings with deep meanings. You will learn what is right and honest and fair. From these, an ordinary person can learn to be smart, and young people can gain knowledge and good sense."
So are you a person? Of course you are. Do you want to know godly wisdom and learn how to discern situations in life? I hope so, or else you wouldn't be doing this study. Are you simple or ordinary? Hey, we all are simple in certain areas of our lives. We're not all that deep! So we fit the description of someone striving for wisdom.
Verses 5 and 6 also talk about what a wise person would do. "If you are already wise, you will become even wiser. And if you are smart, you will learn to understand Proverbs and sayings, as well as words of wisdom and all kinds of riddles" (Proverbs 1:5 - 6 CEV).
I also like verse 5 in the Amplified Bible, Classic Edition, which says, "The wise also will hear and increase in learning, and the person of understanding will acquire skill and attain to sound counsel (so that he may be able to steer his course rightly)."
