“Tongue is a beast, if it is let loose, it devours.”

“The human tongue is a beast that few can master.”

“Let thy mind rule thy tongue!”

“… But the human tongue is a beast that few can master. It strains constantly to break out of its cage, and if it is not tamed, it will tun wild and cause you grief.”

“Mulch's tongue lolled out, resting on the centaur's neck. "Mmm," he mumbled around his tongue. "Horse. Tasty"

"Let's go," said Foaly nervously. "Let's go right now.”

“Let a fool hold his tongue and he will pass for a sage.”
Taciturnitas stulto homini pro sapientia est.

“For God's sake hold your tongue, and let me love.”

“If we can only speak to slander our betters, let us hold our tongues.”

“If, drunk with sight of power, we loose
Wild tongues that have not Thee in awe,
Such boastings as the Gentiles use,
Or lesser breeds without the Law —
Lord God of Hosts, be with us yet,
Lest we forget—lest we forget!”

“From all who dwell below the skies
Let the Creator's praise arise;
Let the Redeemer's name be sung
Through every land, by every tongue.”
