What does Proverbs 1:9 mean?

Verse 9 likens our parents to a garland or a pendant. This custom of adorning oneself with jewelry has not changed much in thousands of years. Jewelry is a status symbol and serves as an item of beautification. Solomon gives a clear picture that parents (more specifically the instructions of parents) are not to be despised. Instead, they should be seen as treasures.

The wise instructions of a parent, like fine jewelry, are often obtained at great cost. They have history, value, and can even be passed along to future generations. Further, those who actively use the wisdom of their parents will see it reflected in their lives. Other people will notice the wise choices, wise behavior, and wise words, just as someone will notice the fine jewelry a person puts on. In terms of wisdom, this is far better than jewelry, since wisdom can be spread to others who see it and learn from it.
