Matthew 15:11, 17-19

It’s not what goes into your mouth that defiles you; you are defiled by the words that come out of your mouth.”

“Anything you eat passes through the stomach and then goes into the sewer. But the words you speak come from the heart—that’s what defiles you. For from the heart come evil thoughts, murder, adultery, all sexual immorality, theft, lying, and slander.
