One thing we must learn when moving from childhood to adulthood is when not to speak. While there are countless times when it is appropriate to speak up, speak out, and speak loud when doing so, we must come to understand the finesse that is called for in human interaction. There is an old military saying-- "loose lips sink ships". It's a good one not just for covert military operations, but life itself. When we have something good and constructive to share with others, let the lips be free. When our hearts want to share hurtful and destructive things, we need to tighten up. How many of the relational problems you've encountered over your life have dealt with ways of speaking (or not speaking) to the people who are important to you? We don't always behave godly. That's why this Psalm pertains to all of us. Know when to speak and what to say when you do. Know when to be silent. That will help you escape the relational destruction of life.
