3:21-22Meaning
Keep wisdom in sight; it sustains and adorns The speaker addresses “my son” and calls for wisdom and discretion not to “depart from your eyes,” meaning they should remain continually attended to. The stated result is twofold: they become “life” for the inner person (“your soul”), and they become “grace” for your “neck,” suggesting an outward mark of favor or honor, like something worn and seen.
