Boomerang

Proverbs 18:21 Death and life are in the power of the tongue: and they that love it shall eat the fruit thereof.

Power-possession of control, authority, or influence over others

What are you using your words for?

Death and life, good or bad, tear down or build up. There is so much potential in your tongue.

"You get what you pay for"…meaning you will get rewarded for your speech, either with good or bad depending on what you say.

It is like a boomerang, your words will come back to you.
