Proverbs 21:28

God punishes people who lie. Lies are evil (Deuteronomy 5:20; Mark 10:19). But a good listener will say helpful things. Such a person learns from what he hears. So his words will not suggest a wicked scheme.

The second line might mean, ‘The words of a man who does not lie will always be true.’ Or, ‘The man who listens to lies will also die.’ Or, ‘The man who hears a lie will tell everyone.’ Or, ‘People do not forget an honest man.’

Perhaps the second line means many different things. Perhaps Solomon intended this. Each of these possible meanings teaches a true lesson.
