Power of the Tongue

The tongue has no bones, but is strong enough to break a heart.
So be careful with your words.

The tongue has the power of life and death, and those who love it will eat its fruits.
Proverbs 18:21

The tongue is a small thing, but what enormous damage it can do.
James 3:5

Whoever keep his mouth and his tongue keeps himself out of trouble.
Proverbs 21:23
