James 3:5–6 uses fire as the governing image for the tongue: "how great a matter a little fire kindleth." The tongue that carries and distributes damaging information about someone is a fire — its direction and final extent are not controlled by the one who lit it. Proverbs 26:20 offers the practical principle: gossip requires a listener. "Where no wood is, there the fire goeth out." The person who refuses to receive gossip is not simply being polite; they are removing the fuel.
Ephesians 4:29 defines healthy speech positively: it should "minister grace unto the hearers." This is the standard against which all other speech is measured. The question is not only "is this true?" but "does this build up the person who hears it?" Information about someone's failure, even if accurate, can be shared in ways that minister no grace to anyone in the conversation.
