Warning against adultery.
v.20-22 The son is called upon to follow the commands of his parents in what follows. Bind them on your heart continually. This will bring benefits all the time (v.22).
v.23-24 The parents command will illuminate the path the son is to follow — stay away from the evil woman/adulteress.
v.25-28 Don’t fall for her eyelashes (beauty). There is no escaping the consequences and it may cost your life.
v.29-35 Adultery will not go unpunished — he who does it destroys himself. There will be no pity on him.
With punishment and shame so certain, one must be a fool to commit adultery. Follow the advice of the parents in this passage and keep far away from her. Guard your mind because that is where infidelity starts.
