16Jesus said, “Even after all that I’ve taught you, you still remain clueless? 17Is it hard to understand that whatever you eat enters the stomach only to pass out into the sewer? 18But what comes out of your mouth reveals the core of your heart. Words can pollute, not food. 19You will find living within an impure heart evil ideas, murderous thoughts, adultery, sexual immorality, theft, lies, and slander.e 20That’s what pollutes a person.
