Lips and Tongue
He who guards his lips guards his life (The Bible).
Some of us are old enough to remember a slogan of WW II: “Loose lips sink ships,” an idiom meaning “beware of unguarded talk.” That may not be of much concern today, but the warning to watch your tongue is always appropriate. Your words may not create a war danger, but they can certainly hurt people, even to the destroying of a person’s reputation and character.
Those who control their tongue will have a long life; opening your mouth can ruin everything. (Proverbs 13:3)
