Every proverb can be expanded on indefinitely.  The very sentence that says that if any think they know something, they don't know it as they ought to.  Thus, to read a proverb and think one knows or understands it, means they have deceitful pride.  One should not read a proverb and think such a thing or they bring about a cage upon themselves.  Pride and arrogance are traps.

Proverbs 10:3.  A puzzle piece with parts to itself.  And parts to those parts.  Not to be added to nor taken away from.

Slacker.  [looked up scriptures pertaining to this word]  If one breaks one wise saying, they break each other one.  In this, they also become a fool, in addition to a slacker, a lawbreaker, and many other things.  When the different types of individuals were listed, or different wrongful attitudes, or even the righteous attitudes, they pertain to whole groups, and as such, there really will not be sitting on a mid-point.  One is either on a positive narrow path to Father, or on the wide path to destruction.

How does one read scripture, a wise saying, apply it to oneself, but not receive the pain of such a possible rebuke?  Desiring mercy and not sacrifice.

Proverbs 11:1  The accurate weight begins in Father, and can come into one's heart, and then expressed outwardly.

James 4:10  how does Father exalt those who humble themselves before Her?  It is to invest in Father's Spirit and Her Will by humbling oneself before Her.  Buying gold refined by fire.  One should not feel guilty or shame in following Father's Spirit, even when She directs oneself in activities that may be extracurricular.
