My son, let them not depart from your eyes—keep sound wisdom and discretion; So they will be life to your soul and grace to your neck. Proverbs 3:21, 22
Let them not: expressing a prohibition
Depart: be perverse, contrary
From your eyes: sight, figurative of mental and spiritual faculties
Keep: watch, guard, preserve, to protect, maintain, obey
Sound wisdom: efficient wisdom, abiding success
Discretion: power of devising, intent, purpose
So they will be: become, result
Life: as welfare and happiness, consisting of earthly felicity (state of being happy) combined with spiritual blessedness
To your soul: living being
Grace: favor, elegance
Neck: ornament around the neck
Looks good on you!
Not only do wisdom and discretion allow you to enjoy life knowing that you are doing what God wants, but they look good on you! The result of keeping wisdom and knowledge in your "awareness zone", will allow you to filter your thoughts and actions through God's wisdom. And as you keep the perversion of truth away, you're appearance will be that of happiness and grace.
Looks good on you! We've seen people that seem to glow from within—they look beautiful and radiant. That is what wisdom provides—that growing grace.
Looks good on you! It all begins with the heart. A heart that is permeated with a deep sense of reverence for God is where the wisdom flows forth. When the heart is full of respect for God, then there is a strong desire to preserve wisdom and live in obedience to that wisdom.
