keeps one's mouth shut
Doesn't say anything
To keep one's mouth shut is to stay silent, especially about something sensitive or secret.
The phrase implies deliberate restraint—not speaking when speaking might cause trouble: Just keep your mouth shut about what you saw.
It can also be a blunt command to stop talking: Keep your mouth shut and let me handle this.
