What are the consequences for evil speech? The Zohar speaks of those who speak with a vicious tongue attacking others. Their behavior will revert back on themselves. A form of leprosy will attest to their cruelty. In the past their homes would reveal their sinister activities and have to be destroyed and out of this would emerge combating spirits from above and below and once they destroy each other, then a purifying process can be applied to clear the defilement.
