What more to say? The title summarizes it.
“Guard your mouth.” It’s from the Bible but I’ve heard it from one of my colleagues. Less talk, less mistake.
Set a guard over my mouth, LORD; keep watch over the door of my lips.
Evildoers are trapped by their sinful talk, and so the innocent escape trouble.
Those who guard their lips preserve their lives, but those who speak rashly will come to ruin.
The tongue has the power of life and death, and those who love it will eat its fruit.
