Proverbs 15

If I counted right there are 12 reference to speech in this collection. These proverbs exalt words that are compassionate, honorable, righteous, and loving. They also condemn those who speak from folly or evil. If I grasp the meaning of verse 26 God loves to hear us speak words of grace. Words that convey what people need rather than what they deserve. That goes against our sense of "fairness" but that type of speech God considers "pure". So I'm wondering if God would rather hear us speak gracious than condemning words to anyone who has offened us? Maybe even for those who have offended him.
It took me almost 5 minutes to read this chapter.
