A clear sign of wisdom is turning away from sin; before considering its effects, note that the text provides clues to what the author means by sin: injustice (3a.8), cruelty and arrogance (3b), contempt for correction (6), and boasting (7). These evils must be avoided because they are highly destructive; they are like a double-edged sword, harming not only those who succumb to them but also their fellow people. The passage concludes with the key advice: follow the Law that guides your thoughts and respect the Lord as the path to true wisdom.
