"The boneless tongue, so small and weak,
Can crush and kill", declared the Greek.
The Persian proverbs, wisely saith
"A lengthy tongue, an earthly death."
Sometimes it takes this form instead:
"Don't let your tongue cut off your head."
While Arab sages this impart:
"The tongue's great storehouse is the heart."
From Hebrew wit, the maxim's sprang:
"Though feet should slip, don't let the tongue."
A verse from scripture, crown the whole:
"Who keep the tongue, doth keep his soul."

"He who guards his mouth and his tongue keeps himself from the Calamity." Proverbs 21:23 NIV
