THE POWER OF THE TONGUE - SPEAK TO WARN THEM

Proverbs 18:21   -  Death and Life are in the Power of the Tongue: and they that love it shall eat the fruit thereof.

Ezekiel 33:8  -  When I say unto the wicked, O wicked man, thou shalt surely Die; if thou dost not Speak to Warn the wicked from his way, that wicked man shall die in his iniquity; but 

HIS BLOOD will I require at thine HAND.
